t seems recently that every conversation I have ends up turning towards the topic of data and the problems independent garages can have accessing it. Ok, when I say every conversation I mean every work-related conversation. Outside of work I have plenty of non-data related conversations about food, rock music and books, but nothing else. But once car repair is involved, data, diagrams, information become the hot topic.

The timing is somewhat propitious: things seem to be going well on the motor vehicle block exemption front, with legislators finally listening to the needs of the aftermarket for fair access to data. But what has struck me lately is not the wider arguments surrounding data, but literally what it means for garages themselves. Ben Johnson, our Finland-based diagnostics expert, writes this month about the benefits of keeping your own data file – manually compiling a database of examples to compare future vehicles to; he also mentions scouring the web in search of the right diagrams.

Knowing how something is meant to perform is crucial to understanding when and how something is malfunctioning – usually necessary steps to take on the way to discovering why it is malfunctioning. It can pay dividends to assess what data you might need in the future and to gather as much as you can when you get the chance. In an ideal world everything you need would be neatly packaged for you in one place. That would certainly make this magazine obsolete and might even make your own job obsolete. The truth is that cars are chaotic, faults are endless and causes are often multiple. There never will be a “click here to resolve the issue” button, but fairer and easier access to vehicle data will at least allow you to provide the service your customers expect.

Let it snow, please let it snow!

By the time you read this we will be fully ensconced in the season formerly known as Christmas, now known the world over as Mariah Carey Season. It takes some effort to will myself into x-mas mode, seeing as we haven’t yet had Halloween or Guy Fawkes night (remember him?). However, it has been made a little easier by the supermarkets who have elected to leapfrog the spookier holidays and have been proudly stocking mince pies since, and I can’t quite believe this as I write it and had to double check, the start of September.

September, if you remember, was this year the beginning of summer, not the end of it. Perhaps UK supermarkets are getting us prepared for a globally-warmed future in which christmas dinner is barbecued turkey skewers on the beach – don’t go for a dip though, by that point Thames Water will have dispensed with the niceties and every sewer in London will just pour directly into the river. But hey, we’ll still have Mariah!

EV qualified workforce grows... slowly

FOR THE DIARY

Latest IMI analysis reveals that 20 per cent of the UK aftermarket population is now qualified to work, to some level, on electric vehicles.

In Quarter 2 2023 2,900 technicians achieved EV certification, bringing the total number of qualified EV technicians in the UK to an impressive 45,300.

However, the rate of EV qualifications appears to be slowing, with a 36 per cent decline in certifications year-on-year. And compared to the previous six-months there’s a 26 per cent drop in certifications. Early analysis by the IMI of quarter three data suggests that this trend is persisting with a 7 per cent decrease compared to the same period in 2022.

by Hilton, Milton Keynes on Thursday 7th of December. The conference features a line-up of leading industry voices, and in the evening, delegates will be invited to the awards dinner, with Tom Allen, opening a show that recognises outstanding achievements across the automotive aftermarket.

The IMI predicts that by 2030 the sector will need 107,000 EV trained technicians, increasing to 126,000 by 2032, increasing to 185,000 by 2035. This analysis comes as Rishi Sunak pushes back ban on new petrol and diesel cars back 5 years to 2035.

Net zero outlined A week after Prime Minster Rishi Sunak announced the ban on the sale of new ICE vehicles has been shifted back 5 years to 2035, the government published a ZEV mandate.

This confirmed that 80 per cent of new cars sold by 2030, and 70 per cent of vans, will be required to be zero-emission by 2030. The mandate also means that 22 per cent of new cars sold in 2024 are to be zero emission, Chief Executive of the SMMT Mike Hawes commented that “with less than 100 days to go, manufacturers finally have clarity on what they are required to sell next year and up to 2030.” Also stating that the mandate will “challenge” the industry.

QUOTES “ Garage Hive’s The Blend 2023 saw some 330 attendees at this year's event. The event brought together workshops and business owners from the UK aftermarket, delivering advice on best business practices, with a wealth of industry expert speakers providing relevant and current topics. This included Matt Cleevely from Cleevely EV garage and Jennifer Webb from HR vitals.

It is a relief to at last see the Conservative Party recognising that motorists have been treated pretty poorly over the last decade...However, there is absolutely no mention of supporting the workforce that is fundamental to motorists – and businesses - being able to stay on the roads.”

Steve Nash, CEO of the IMI criticises the Government’s ‘plan for drivers’ which aims to protect drivers from “over-zealous” traffic enforcement.

ULEZ camera facing the wrong way?

Transport for London has apologised after 927 drivers in Harrow were incorrectly charged when a ULEZ camera was pointing in the wrong direction.

This forced TfL to switch off the camera, before reinstating it in the correct direction, and issuing refunds totalling £11,200.

The deputy leader of Harrow Council, Marilyn Ashton, has called this “unacceptable, incompetent and disgraceful” especially considering how long it took TfL to respond to the complaints she received, and the fact that the camera wasn’t actually in London at all.

New MOT measures At the IGA member event in Runcorn, the Driver and Vehicle Standards Agency (DVSA) announced new annual training measures for MOT testers who fail to complete their annual training within the annual training year.

Currently, MOT testers failing to complete the year’s annual training are required to do a demonstration test with the DVSA and complete the current year’s

annual training.

As of January 2024, MOT testers who fail to complete the year’s annual training who later want to be reinstated as an MOT tester, will be required to complete a DBS check, a DVSA demonstration and the current year’s annual training. The DBS check must be uploaded to the MOT admin hub and be available at the time of the DVSA demonstration.

Get the most profit on bulbs this winter To prepare garages for winter, Ring Automotive has taken a look at what opportunities are regularly missed by workshops and offers suggestions on how to get the most profit with bulb sales.

One of these tips is replacing bulbs in pairs when replacing a blow bulb in a paired lighting system. If one headlamp or brake light goes, replacing the bulb in the other at the same time produces an even light output to aid driver’s vision. Plus, it provides a higher level of customer service. Headlamps

work at the same time, therefore it is logical to presume that if one headlamp bulb goes, the other bulb in the other unit will also fail shortly. A motorist would be frustrated to have to replace another bulb soon after having a car in the workshop, so it’s always worth replacing bulbs in pairs for these reasons.

This extra professional advice, delivered with confidence can lead to extra sales, but also opens the door to sell upgrade bulbs, which come as pairs.

THE

PMM PODCAST

This month we bring you a snippet of the chat between PMM editor and host of the PMM Podcast, Kieran Nee and CEO of the IGA, Stuart James. Here, the two discuss the SERMI scheme and why Stuart feels it’s important for the UK independent aftermarket looking to access security and repair-related vehicle data.

Are vehicle manufacturers trying to in some way restrict independent garages from accessing to security-related RMI? Morning Stuart. Could you explain why you feel the SERMI scheme is necessary for independent workshops?

For many years, garages worked on all makes, models, years, all types of cars.

However, to access certain levels of information to repair those cars effectively for their customers has become a challenge over the years.

Each vehicle manufacturer has a different way of accessing their information, a different way of regulating the security of that information and ensuring that vehicle theft doesn’t increase in the UK. In many

cases the approaches used have been correct. However, it’s very frustrating and very difficult for garages to log in to a different vehicle manufacturer every time they want to get access to fix that car.

What this system brings is one login through a conduit called a trust centre that takes them to every manufacturer. So it's one route into all manufacturers. It's a revelation in the ability of independents to repair cars.”

Over 70 per cent of all service and maintenance work is carried out within the independent sector, I don't know if you're aware of that. If all drivers went to franchise dealerships, their lead times would be significantly larger than they are now. We are working very closely with the vehicle manufacturers on this, which in itself is quite unusual. We are

representing the independent garage sector and the vehicle manufacturers have been really quite agreeable all the way through this.

I think we can all see that this is the future and it will be good for the UK and for the consumer, the rigorous checks that a technician has to go through and prove their integrity can only be a good thing for our industry.”

“Over 70 per cent of all service and maintenance work is carried out within the independent sector.”

So which common jobs will be affected by the SERMI scheme?

Routine servicing won’t be affected. However when you change a component, you may have to program that component in. When you replace keys or when you need to access an electronic control unit that has

10 DECEMBER 2023 PMM

security level components within it, you won’t be able to get in unless you have SERMI access. Also for newer systems like ADAS systems, sometimes you have to go through the security gateway.”

joint from the gearbox flange, disconnect the N/S/F bottom ball joint (Fig.3) and ease the strut assembly out. This can be held out of the way by placing a block between the strut and the inner wing (Fig.4), which saves having to remove the driveshaft from the hub.

Remove the lower gearbox pendulum mount and then the O/S driveshaft heat shield, unbolt the O/S inner CV joint and secure the driveshaft away from the gearbox and remove the O/S drive flange from the gearbox by unscrewing the centre allen bolt.

Support the engine using a suitable engine support, remove the lower bellhousing bolts, but leave an easily accessible bolt to support the gearbox. Remove the upper gearbox mounting and lower the engine and gearbox slightly to aid gearbox removal. Support the gearbox using a transmission jack, remove the final bellhousing bolt and then carefully ease the gearbox away from the engine.

Once the input shaft is clear of the clutch assembly, lower the transmission jack and remove the gearbox from the vehicle.

Gearbox installation

With the gearbox disconnected, remove the six clutch pressure plate bolts and the clutch assembly. At this point the clutch fault in this repair was evident, as the clutch plate lining had reached the end of its service life as it had worn down to the metal retaining rivets. As this vehicle is fitted with a solid flywheel, remove the clutch dust using clutch and brake dust cleaner, remove the glaze from the flywheel surface using an emory cloth and clean again

with a clutch and brake dust cleaner.

Focusing on the gearbox, remove the release bearing and fork assembly, then check the guide tube and pivot points for wear. In this instance, we replaced the guide tube, pivot point and release arm, as wear was evident (Fig.5). Clean the bellhousing area removing the old clutch dust using a clutch and brake dust cleaner, then apply a light smear of high melting point grease to the splines on the input shaft and mount the new clutch plate onto the shaft, which will confirm the clutch plate is correct, as well as evenly distributing the grease. Remove the clutch plate and wipe away any excess grease, then, using a clutch alignment tool,

mount the new clutch onto the flywheel ensuring the clutch plate is faced correctly, indicated by “gearbox side” (Fig.6). Insert and tighten the six clutch bolts in an even and sequential process and then torque to the manufacturer’s specification.

Before gearbox installation, ensure the engine to gearbox alignment dowels are positioned correctly and that all items that could foul the gearbox are out of the way.

With the gearbox positioned on the transmission jack, bring the gearbox close to the engine. Spend a little time aligning the gearbox to the engine and then ease the gearbox input shaft into the clutch plate, push the gearbox onto the alignment dowels and secure in position with a couple of easily accessible bellhousing bolts. Bring the engine and gearbox into position and fit the gearbox mounting and tighten in position.

Installation is in reverse order of removal, torque required bolts to the manufacturer’s specification and these values are available on Schaeffler’s REPXPERT workshop portal.

After the battery lead has been reconnected, reset all electrical consumers and carry out a full road test to ensure that the repair has been successfully completed.

his month, I want to emphasise the significance of building your personal library of information and underscore why it holds such a vital role in our work. Let’s delve into the world of BMW, a company that continually provides us with an abundance of diagnostic challenges, keeping us on our toes. While this constant stream of issues keeps us engaged, what's less than ideal is BMW’s tendency to withhold crucial data – practically none at all. Even in the realm of technical training, based on my experiences working with both BMW dealerships and specialists, there’s a conspicuous lack of information regarding what things should look like when they go awry.

Dreaded MIL illuminated

Finding the problem This week brought another typical job into my garage, an F15 X5 Hybrid. But unlike the usual suspects – BDC failures and gearbox meltdowns – this one presented a good old timing chain problem. Timing chain issues are no stranger to us, as they are a common occurrence in many workshops. However, what set this one apart was my decision to employ a scope to analyse it, capturing the waveform for my personal library.

Admittedly, my library is a bit scattered and disorganised, with data strewn all over the shop, but one thing is certain – I have an abundance of invaluable data and this is the point that I am making – all of us should maintain such a collection because, as you'll discover as you continue reading, knowledge not only saves a significant amount of time but can also pave the way for those coveted monthly bonuses we all strive for.

The engine sounded surprisingly smooth, but the ominous glow of the MIL (malfunction indicator light) in the corner

was a silent testament that all was not right (Fig.1). The customer had thoughtfully provided us with the fault codes, most likely retrieved from a dodgy looking USB dongle that I had noticed plugged into the diagnostic socket during my attempt to connect the new Thinklink – the wireless diagnostic link from the Thinktool we recently acquired.

With the Thinktool at the helm, it swiftly retrieved the fault codes from the DME. Among them, the exhaust camshaft synchronisation with the crankshaft fault code appeared, immediately sparking my suspicion of a stretched timing chain. Yet, a dilemma arose. While I’ve scoped chains for potential stretching over many years, BMW makes it more complex due to the unique nature of each engine. Take the S series V8, for example – not a walk in the park to interpret, I assure you. The X5 I was dealing with featured the N20 engine with twin Vanos and a centrallymounted Valvetronic servo motor, easier to interpret the valve timing than a V8 however my problem was clear – I had no reference scope pattern to compare it to. A quick online search led me to an invaluable resource in Kyiv, Ukraine – Rotkee. Although they

130F20. A sign that the timing may be off.

��� primarily deal in car diagnostic tools, their waveform repository proved to be a treasure trove. This is where I found a reference image of an N20 engine with a pristine timing chain – one free of defects such as stretching or vanos sprocket anomalies. It’s moments like these that highlight the paramount importance of having a well-organised reference library, wouldn't you agree?

The fault code 130F20 immediately caught my attention (Fig.2), as I’ve encountered this issue countless times in N20 powerplants, and it has consistently pointed to a stretched timing chain. However, in the spirit of thoroughness, I saw an opportunity to put the Thinktool scope through its paces and create a record for my personal library.

The code 120308 could be as a result of the exhaust camshaft timing fault. I may be able to confirm that link in a future follow up article. This article primarily will focus on the timing issue initially.

���

The magenta trace shows the exhaust camshaft in relation to TDC at the crankshaft (yellow trace).

Connecting the Thinkscope is a breeze – simply attach the USB to the Thinktool and insert it into the scope box, connect your BNC cables, and you’re ready to go.

Backpinning wasn’t an option due to the DME’s small connectors (NANO MQS) and delicate wiring, so I opted to expose a small section of outer sheathing and attach crocodile clip probes for a secure and reliable connection. After configuring channel one for the crankshaft signal and channels 2 and 3 for both camshafts, all that remained was to press “auto”, and the Thinkscope handled the waveform – a substantial timesaver compared to the antiquated AVL Di-Test, now relegated to the scrap heap.

The scope revealed a vivid image (Fig.3), making it evident that the exhaust camshaft was out of alignment with respect to TDC (indicated by the yellow trace) on the crankshaft. However, here’s the catch: in

Both camshafts are in a similar position to the case study intake camshaft which was correct. Both camshafts are synchronised to the crankshaft correctly. Image courtesy of Rotkee/VWAUDI.

certain BMW engines, the valve overlap you see in the magenta and blue traces can appear deceptively similar, even in engines without any faults. The N20, on the other hand, offers a more straightforward and distinct pattern. It comprises exhaust and intake cams with no overlap, but once Vanos and Valvetronic come into play, things can change. Perhaps, on a future occasion, I should create a waveform to record the independent advancement and retardation of the camshafts. In its current state, the engine operates under no load, and the variable valve timing should be in a neutral position – or at least, it should be. To gain a better perspective, take a look at another waveform I found on Rotkee’s website (Fig.4).

Tackling the problem To address this issue, my first step was to tackle the laborious task of removing the cam cover, a challenge exacerbated by the imposing presence of the X5 wrapped around me. With the cam cover out of the way, I could then directly access the exhaust camshaft to inspect why it was not synchronised. Employing a spanner, I turned the camshaft and scrutinised the Vanos sprocket – to my satisfaction, there was no play or slackness, effectively ruling out any mechanical problems. However, I strongly recommended replacing this sprocket, along with the intake sprocket, as using a new chain with old sprockets is a practice best avoided. Furthermore, there were no fault codes reported for the Vanos solenoids, which, on the N20, have established themselves as dependable, unlike the earlier N43’s long finger-type solenoids.

Intake cam timed correctly. Note the QR code at the 12 o’clock position.

Exhaust camshaft not at the 12 o’clock position as seen both visually and from the previous scope trace.

20 DECEMBER 2023 PMM

Intake camshaft locked in place correctly.

Upon closer inspection, the intake camshaft appeared to be in good condition, visibly aligned at the 12 o’clock position (Fig.5). However, the exhaust camshaft, as indicated by the earlier scope trace, was noticeably out of sync, resembling a position closer to 7 minutes past the hour, if that description makes sense (Fig.6).

For many years, BMW engines have embraced keyless design, lacking dowels or woodruff keys, even on the crankshaft. This feature elevates the importance of precise timing. Once the Vanos sprockets are removed and then replaced, and the timing chain is reassembled, the use of camshaft phase wheel locking tools becomes indispensable to ensure that cam timing is impeccably aligned.

The phase wheels cannot be aligned without a specialised tool. Additionally, this tool proves handy as a visual guide to gauge the extent of timing misalignment on the exhaust camshaft before repair.

You may have noticed that I refrained from locking the crankshaft during this repair process. I found no need to invest additional time in this step, given the challenging location of the locking pin orifice, which would have consumed an unreasonable amount of time to remove the blanking pin and secure the engine.

The compelling evidence lay in the absence of intake camshaft/crankshaft correlation fault codes, indicating that the crank timing was essentially correct and the intake camshaft timing also correct. In a situation where time was of the essence – as the customer surprisingly desired the car’s swift return – this decision was pivotal (Fig.7).

���

Not surprisingly, the exhaust cam phase wheel was a mile out.

The replacement of the timing gear is scheduled for completion next week.

However, on that very day, I had to ensure the car was ready to go back to the customer.

Such is the relentless pace and pressure of a fault finder’s daily life.

I hold a strong conviction that a new chain and a set of Vanos adjusters (sprockets) will effectively resolve this problem. This case study serves as a reminder of the pivotal role that your own reference library plays. This job, from reading fault codes to setting up the scope, researching online to interpret values, and the final step of physically removing the cam cover for visual confirmation, took approximately three hours. It's essential to remember that when faced with a potential stretched chain, a swift and precise diagnosis can save a significant amount of time without needing to loosen a single bolt or getting one's hands excessively dirty. With the right library of data and a strategic approach, we can all work more intelligently, ultimately saving time for both ourselves and the customer while contributing to reaching that monthly bonus sooner. Until next time, keep learning and keep improving every day. I hope that this article has inspired you to begin building your very own reference library because it will be the best decision that you make as you continue down the path of self development.

EV Wireless power transfer (WPT) is a system for wirelessly charging the batteries in electric vehicles. There are two main methods: Stationary WPT Dynamic WPT

With stationary charging, the electric energy is transferred to a parked vehicle. In dynamic wireless charging systems, the energy is transferred via a special driving lane equipped with a primary coil system at a high power level to a secondary coil of a moving vehicle. Because the range of most EVs is now good, the need for dynamic charging has reduced. I will, therefore, concentrate on static or stationary WPT. To wirelessly charge, a suitably equipped electric vehicle simply parks over an induction pad and

CHARGING WIRELESS POWER TRANSFER charging commences automatically. Just like with wired connections, the rate of charge is set from within the vehicle. There are no visible wires or connections. A primary charging pad is buried or set on the ground (on a drive or in a garage for example) and a secondary pad is integrated onto the vehicle.

The power supply (Fig.1) takes a mains voltage input and produces high-frequency current (>20 kHz). Its output current is controlled and applied to the primary pad.

Power is transferred from the primary pad to the secondary pad using transformer action. The onboard charger takes power from the receiver pad and provides a controlled output to the battery. The controller is required to provide an output that

remains independent of the load and the separation between pads.

BMW has developed a wireless charging system. As soon as the vehicle has been parked in the correct position above the inductive charging station (Fig.2), a simple push of the stop/start button, starts the charging process. Once the battery is fully charged, the system switches off automatically just as if it was plugged in.

The system helps the driver to manoeuvre the car into the correct parking position with the help of a Wi-Fi connection between the charging station and vehicle. An overhead view of the car and its surroundings is displayed in the centre control display. Coloured lines help guide the driver into the correct spot.

A graphic icon shows when the

correct parking position for inductive charging has been reached. This can deviate from the optimum position by up to 7 cm longitudinally and up to 14 cm laterally.

The contactless transfer of energy between the GroundPad and CarPad is conducted over a vertical distance of around 7.5 cm. The GroundPad generates a magnetic field. This induces a voltage in the CarPad, which then causes a current flow to the onboard charger (just as if the car was plugged in).

WPT is designed for slow charging so is ideal for home chargers where, for example, you simply park the vehicle as normal and charging automatically takes place overnight.

KNOW YOUR PARTS Positive Crankcase Ventilation febi takes a detailed look at crankcase emissions, as well as outlining some common cases where the emissions ventilation system fails.

C

rankcase emissions are produced as a result of the combustion process of the internal combustion engine. These are a by-product of this process, with exhaust gases escaping from around the piston rings and into the crankcase. The overall volume of these gases varies depending on cylinder pressure, piston ring pressure and component wear. The elements found in these blow-by gases include wear particles, oil, fuel, gas and air. The specific composition of the elements varies depending on the fuel, engine configuration, engine speed and load, and maintenance history of the engine.

How do they work?

These blow-by gases are typically made up of hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOx), water vapour and traces of sulphates and aldehydes. The crankcase hydrocarbon emissions are normally about 3 per cent of the total exhaust emissions tested at the midlife of the engine. However, due to piston ring tolerances, crankcase hydrocarbon emissions can increase to 20 per cent of the total hydrocarbon emissions.

If not controlled, these gases can contaminate the lubricating oil, resulting in sludge. The crankcase can be pressurised – causing oil seals to fail – which, in turn, can lead to oil leaks, as well as having an impact on the starting and the smooth running of the engine and exhaust emissions.

Positive crankcase ventilation is a system that was developed to regulate the internal engine pressure and remove harmful vapours from the internal combustion engine. This prevents these vapours from being expelled into the atmosphere.

24 DECEMBER 2023 PMM

024_PMM_DEC23_Layout 1 30/10/2023 08:51 Page 25

Rocker Cover with vent valve

The PCV system does this by using a manifold vacuum to draw vapours from the crankcase into the intake system. The separated droplets of oil flow back to the oil sump and the cleaned blow-by gases are recirculated into the intake area. They are then carried with the fuel/air mixture into the combustion chambers, where they are burned. Every car has some form of crankcase ventilation system, which can consist of several basic parts including hoses and connectors, an oil separator and a ventilation valve. These components can be separate or built into the engine.

The most typical defects of a crankcase ventilation system are a rupturing of the rubber valve membrane and blocked or split hoses or ducts. This leads to high oil consumption, burning oil, loss of power, misfiring, and high carbon deposits. Early signs of a failing PCV system include whistling noises from the intake, blueish smoke in the exhaust, high oil consumption, and thick white or yellow residue under the oil cap. However, many of these symptoms can go unnoticed or be misdiagnosed – mistaken for other issues or components.

Here are a few common crankcase ventilation system examples:

Breather Valve for crankcase

Land Rover Freelander TD4 and Range Rover TD6 The engine oil is leaking – usually from the dipstick tube, because the dipstick has been pushed out under crankcase pressure. Other symptoms include lack of engine power (the engine will not increase in speed), black or blue exhaust smoke and excessive oil consumption.

These are caused by a blocked crankcase breather filter – this filter is located in the depression control valve assembly, which is fitted to the camshaft cover. Replace the blocked filter and the complete breather valve assembly, clean any excess oil leaks, and test.

Various Volkswagen, Audi, SEAT and Skoda models, fitted with the 1.8 or 2.0 FSi/ TFSi engine The engine crankcase is maintained in a constant vacuum while the engine is running.

The engine is equipped with a crankcase breather valve installed on the rocker cover, directly connected to the intake manifold.

The crankcase blow-by gases are separated into two stages. Firstly, the primary oil separator in the oil filter housing removes the majority of engine oil from the gases. Secondly, the separator on the rocker cover removes the remaining engine oil vapour from the gases.

The turbocharged variants have a more sophisticated pressure control system. A twostage pressure control valve is located on the rocker cover. When the intake manifold vacuum is present, blow-by gas flows into the intake manifold. When turbo-boost pressure is present, the one-way valve in the breather valve assembly closes and blow-by gases flow into the valve cover.

Over time, contamination causes reduced air flow and the rubber membrane can split in the oil separator. Additionally, the sealing joints between the breather hoses become dry and do not seal.

The faulty oil separator or hoses cause the following symptoms: engine idle speed to fluctuate and stall, whistling noises from the engine at idle speed and increased oil consumption.

Various BMW models, fitted with the N20 engine In earlier BMW engines, the crankcase ventilation system was designed to be outside the engine. In the N20 engine – and many others – the crankcase ventilation valve is built into the top of the rocker cover.

The blow-by gases pass through the opening in the intake side, with spring tab separators in the rocker cover. The oil in the blow-by gases is separated by the spring tab separators and flows along the walls, down through a non-return valve and back into the cylinder head. The blow-by gas cleaned by the oil now passes into the air intake system.

The most typical defect of this crankcase ventilation system is a rupture of the rubber valve membrane. The rocker cover, which is continuously exposed to heat cycles and vibration, can crack and leak. The oil separator galleries can clog with oil particles and residue.

What was causing noise on the front wheels of the 2017 Audi A5 Sportback?

Autodata helps one garage get to the bottom of why their customer’s Audi A5 was making a metallic noise from the front wheels when manoeuvring and parking.

The problem “A customer's 2017 Audi A5 Sportback is in for a service and the owner has reported a metallic noise from the front wheels whilst manoeuvring or parking. We have heard the metallic noise and we suspected it was originating from the front brake pads due to them being very low. After replacing the front brake pads and road testing the car the metallic

noise is still apparent. Are you aware of other Audi owners who may have reported this type of metallic noise before?”

Find more quick fixes from Autodata on the PMM website!

What does Autodata recommend?

Yes, this fault has been reported to us by A5 Sportback owners with late model year vehicles.

The metallic noise is due to movement between the front wheel bearing housing and the front hub carrier. Remove the front wheel bearing housing from the hub carrier, but do not remove the wheel hub from the front wheel bearing. Thoroughly clean all corrosion

from the front wheel bearing housing and apply a light coating of Optimolpaste, available from Audi parts department, to the mating surfaces of the front wheel bearing housing and hub carrier. Refit the front wheel bearing housing to the hub carrier. Repeat the procedure for the opposite side and road test the vehicle to ensure the noise has been eliminated.

BEST PRACTICE Working on suspension mounting kits Suspension specialist KYB offers its advice on diagnosing and replacing suspension mounting kits.

J

ust like a shock absorber, a suspension mounting kit is pushed and pulled 1,500 times per mile – over the course of 50,000 miles that means this small but important component has moved up to 75 million times, deteriorating the rubber components in the mounting kit.

Worn mountings have an adverse effect on ride control and safety. Mount wear depends on the type of travel, however a good guideline is that if the struts are worn out, the mounts will probably be worn out too.

Therefore, suspension mounting kits should be replaced every time the struts are replaced.

Mounting kits provide a rubber cushion between the chassis and suspension, helping to reduce stress on the suspension by absorbing vibration. There is also a bearing in front mounting kits which allows the steering wheel to turn the suspension column and the wheels. It returns the steering wheel smoothly back to its natural straight position if released. Suspension mounting kits can affect the angle of how the shock absorber sits – if the rubber is worn, it can cause extra stress upon it and its surrounding components.

How to diagnose worn mounting kits Test driving vehicles is a key part of diagnosing suspension issues and helps to explain the issues to the motorist. Find a short circuit that includes the following: Bumpy road surface/speed bumps (feel for ride harshness) Listen for noises, feel for steering wheel vibration and any irregularities with the steering Turn the steering wheel and release your hands – does it return to its natural straight position?

28 DECEMBER 2023 PMM

Fixing points for the upper suspension mounting kit and the shock absorber to the vehicle.

Rubber element used to absorb vibrations transmitted from the chssis to the vehicle.

The bearing is often placed in a rubber cushion reducing friction and ensuring optimal movement of the shock absorber column while turning wheels.

Construction markings indicate the correct mounting position of the upper mounting.

Pick a route by your workshop that is quiet, and one you can use repeatedly Aim for a 3-minute, 1 mile long route that includes a speed bump, a place where you can brake and accelerate quickly, and swerve safely.

Your speed will not need to be over 30mph When you return to the workshop, eliminate any other factors such as any excessive movement in the other suspension components such as the ball joints and bushes.

Broken/cracked metal – rubber joint This could have been caused by aggressive driving or road conditions such as potholes and uneven surfaces. It can result in excessive vibrations transferred to the vehicle’s steering system and driver, decreasing comfort, increasing fatigue; changed damping parameters of the suspension; accelerated wear of the suspension and co-operating components.

Seized bearing This could have been caused by incorrect installation if the full weight of the vehicle wasn’t applied when tightening the nuts to the required torque. It can result in excessive vibrations transferred to the vehicle’s steering system and driver, increased force will be required to move the steering wheel, the steering wheel will not return to a straight position once the steering wheel is released, and there will be noise coming from the suspension.

Deformation of top support bearing This could have been caused by excessive axle load, or aggressive driving or road conditions such as potholes and uneven surfaces. It can result in excessive vibrations transferred to the steering system, changed damping parameters of the suspension, and noise.

Your guide to

ANTIFREEZE COOLANT Morris Lubricants gives readers the rundown on antifreeze coolants.

F

or anyone running a vehicle with an internal combustion engine, an antifreeze coolant is essential, but it does a lot more than the name would suggest.

Operating at high temperatures…

The best cooling medium is water. However, when the engine reaches running temperature it will exceed the boiling point of water, 100˚C. If the water boils away, catastrophic damage can occur in the engine. To combat this, antifreeze coolants feature the addition of monoethylene glycol, which elevates the solution’s boiling point to around 108˚C.

…and low temperatures If the engine has been at rest and the ambient temperature falls below 0˚C, water freezes, and the ice formed expands. This is a big issue in the engine cooling system as there is nowhere for the expansion to go. As the water freezes, high internal pressures are generated that can crack heads, cause splits in cylinder liners, make hoses leak, fracture radiators and break water pumps. By incorporating monoethylene glycol to the water it reduces the freezing point, potentially driving it down to -35˚C.

Inhibitors Another important function of an antifreeze coolant is to prevent any metallic components from rusting or corroding, such as the engine block, water pumps or gaskets. It is therefore essential that the antifreeze coolant uses the

correct chemistry in its formulation to stop this.

Rusting and corrosion are prevented by an inhibitor package, which is a combination of chemical compounds chosen to optimise its ability to protect the cooling system. This chemistry is referred to as either inorganic or organic acid technology.

Inorganic chemistry is extremely active and will seek out all materials in the cooling system, whether susceptible to rusting or corrosion or not. This constant level of activity results in it becoming depleted after around two years. At this point it should be drained and changed.

Organic acid technology only targets materials where rusting or corrosion is starting to take place. This chemistry is selective and does not become depleted as quickly and will work for up to five years. Some manufacturers may require a combination of these technologies and ‘hybrid’ antifreezes are available for specific engine designs.

And there’s more!

Additional chemistry may also be added to the formulation of antifreeze coolants such as antioxidants to stop corrosive acid formation as well as additional compounds to prevent hard water deposits and extra pH buffering agents to maintain an optimum pH level (around 8). The formation of foam can also inhibit the properties of the antifreeze coolant, therefore an antifoaming agent may be added to the formulation to prevent foam developing within the cooling system.

Colour The language of antifreeze coolants tends to be based on their colour. But be aware, colour is not an indication of quality or performance and is purely cosmetic having no impact on how the antifreeze coolant performs in terms of engine protection.

Choosing the correct antifreeze coolant As engine designs become more complex and engines are manufactured from different metals and composite materials, the correct antifreeze coolant must be used. If not, the antifreeze coolant will damage the engine and reduce its efficiency. When choosing the correct antifreeze coolant, you need to make sure it meets the specifications set by the engine manufacturer.

Antifreeze coolants perform in the engine all year round and do not just cover the winter months. Selecting the correct antifreeze coolant is vital and choosing a product based on colour should be avoided. Best practice is to select the antifreeze coolant based on the engine manufacturer’s specification. If there is any doubt as to which antifreeze coolant is required, check with the engine manufacturer, seek independent technical advice, or use online tools such as www.whatoildoineed.com.

Straightset outlines how you can effectively use wheel clamping systems during wheel alignment.

Working for the

CLAMPDOWN

I

n the garage, precision is paramount.

When it comes to wheel alignment, the importance of precise measurements cannot be overstated. Enter the unsung heroes of this crucial operation: wheel clamps.

These unassuming, yet essential, tools come in various shapes and sizes, each offering unique advantages tailored to different needs.

The choice of wheel-clamping device does play an important part of any wheel aligner and alignment process, especially with the suspension set ups on modern vehicles where accuracy is dependent on fitting the clamps correctly, performing the all-important run-out compensation as well as using a fully calibrated machine and accurately level lift platform.

Initially there was only either a 3-point or 4-point claw type clamp available, though as nearly all vehicles had steel rims this didn’t present any problems with potential damage that can occur if the fingers of the claw grips are themselves damaged or broken. With most of today’s vehicles having alloy rims as standard, solutions to the potential problem of rim damage, as well as speeding up the wheel alignment process, have been available for some years now with the introduction of different clamping styles. Here are some of the systems available today:

damage to alloy wheels and is still a popular choice amongst wheel alignment professionals today. This offers an alternative to a clamp system, and can cater to tyres from 12 inches to 24 inches.

Self-centring clamps With advancements in product design, the self-centring clamp system, which has nylon feet that sit up against the rim with claws that wrap around to grip the tyre, are a very successful design which is still used today and available as an update to the Supertracker CCD system. These clamps automatically centre themselves on the wheel when applied, eliminating the risk of human error. This precision not only ensures more accurate alignments but also enhances the safety and performance of the vehicle and offer a solution to performing wheel alignment on lowered vehicles. With 3-point and 4-point clamps available, these are still going strong today and with suitable extensions that can be used on rims up to 28 inches in diameter.

Specialist clamps Some specialist vehicles and vehicle manufacturers require specialised attention and that includes for wheel alignment. As a leading wheel alignment manufacturer, Beissbarth, began to produce individual clamps for BMW and Mercedes Benz initially, which used pin sets to locate the clamp against the hub with wrap around claws to grip the tyre tread. This type of clamp ignored the rim and measured directly from the hub, allowing for the runout compensation to be skipped but still giving a very accurate measurement.

This spilled out to other marques who wanted a unique, and accurate clamping method, notably Porsche, Tesla, Ferrari, Lamborghini and very soon the JLR range, who have opted for centre mount devices, all machined to very fine tolerances to fit in place of the rim’s centre cap. There are variations of clamp depending on the model.

Hang on system

Magnetic clamps

The hang on system, with no clamping and the use of rim buttons, made popular by Supertracker, eliminated any potential

With the introduction of the Beissbarth ML3D wheel aligner another advancement in wheel clamping was launched: the magnetic

clamp. By using strong magnetic studs they affix to the vehicle’s steel wheel studs. This has proved to be a quick and easy clamp for the technician to use, less cumbersome than most other wheel clamps on the market.

Quick clamps In today’s fast-paced world, every second counts. Q.Grip clamps are designed with efficiency in mind. Their swift application, courtesy of a lever mechanism, streamlines the alignment process. For busy auto shops, these clamps translate into faster turnaround times, increased customer satisfaction, and higher productivity. The latest product from Beissbarth is the Q.Grip, to complement the Q.Lign wheel aligner range.

These are a patented design and provide the technician with a very quick clamp that wraps around the tyre at three points and with the all-important run-out compensation performed have proved to be as accurate as all other clamping devices. Wheel alignment isn't just about functionality; it's also about aesthetics. Nonmarking clamps come to the rescue by using rubber or soft material pads to prevent damage to wheel finishes.

For high-end or custom wheel owners, this means preserving the appearance and value of their investment.

In conclusion, wheel clamps may not be the first thing that comes to mind when thinking about automotive maintenance, but they are integral to achieving precise wheel alignments. Their diversity caters to various vehicles and needs, from quick alignments in a bustling workshop to intricate precision work on specific vehicle manufacturers. By selecting the right clamp for the job, auto technicians can ensure safer, more efficient, and more accurate wheel alignments, ultimately benefiting both customers and their bottom line.

INSIDE INTELLIGENCE SIGN UP FOR A FREE TRIAL AT WWW.RDR.LINK/ABD010

Providing safe, accurate vehicle repairs and getting customers back on the road quickly means starting with the right tools: ALLDATA Repair offers exactly that by providing up-to-date OEM mechanical/body repair information and procedures for 91,950 unique vehicle combinations – more than 95 per cent of all vehicles on the road today. The portal comprises of six million technical drawings and wiring diagrams, including electrical connector views, which are available in five languages.

To show how ALLDATA Repair can be used in the real world, let’s look at a recent case the team has dealt with.

2019 MY PEUGEOT 208 1.2I he team at the ALLDATA Repair Info Centre Service was recently presented with an issue on a 2019 MY Peugeot 208 1.2i. The vehicle owner had been experiencing, what they described, a “dull knocking noise” coming from the front of the vehicle. Bizarrely, though, the motorist would only hear it during warm weather and when the vehicle was at idle. This made the problem difficult to pinpoint and diagnose, making the conversation between technician and customer awkward, potentially.

This period will grant them unrestricted access to original repair and collision information for 36 VMs, all of which have licensing agreements with ALLDATA Europe.

32 DECEMBER 2023 PMM

Thankfully, the ALLDATA Repair Info Centre Service experts were able to come to the workshop’s rescue. They had been presented with this issue before and managed to get to the bottom of the problem quickly.

The cause of the knocking noise was due to internal damage within the vehicle’s front right-hand engine mounting. To rectify, simply, the technician needed to replace the broken mounting, being careful to use the correct VIN number to ensure the correct, modified engine mounting was supplied.

Once the part arrived, to complete a professional and accurate repair, the technician required a specific torque of 6daNM – information available, of course, on ALLDATA Repair!

Mercifully, this intervention from the ALLDATA Repair Info Centre Service meant the technician was able to conduct the work and hand the keys back to a relieved and happy customer – no more knocking noises heard!

Why are the tips of some GLOW PLUGS grey/blue in colour?

One of the OE parts supplied by Denso are glow plugs, so the firm is in an ideal position to dispel an ongoing myth surrounding the part…

A

longside many other products, Denso is a glow plug manufacturer, supplying them as original equipment parts. It also supplies the independent service and repair sector and as its aftermarket range is produced on the same production lines to the same standards, the firm argues they can be relied on by automotive technicians and motorists alike. There is, nevertheless, a notion among workshops that the colour of a glow plugs’ tip can imply that it is not a genuinely new item.

According to the company, the fact that its aftermarket glow plugs are manufactured on the same production line as its OE range, should be enough to reassure those with any concerns over the providence of its glow plugs. However, to clarify the situation and

Colouring, rather than a cause for concern, in fact offers a reassurance of quality

provide peace of mind for installers, Denso is explaining why the tips have this colouration.

In common with many highly engineered products, the manufacture of glow plugs is a complex process. This is particularly true for the production of the glow tube, which when installed, can be heated up to temperatures above 800°C within seconds. This component is needed to ensure a quick and reliable start when the engine is cold, and to reduce emissions when it is running.

Live testing As this heating element is the most critical component of the glow plug and allows it to fulfil its role in the ignition system, its functionality has to be verified during the production process. It is for this reason, that at the end of the production line, the performance of each glow plug is thoroughly tested to ensure that it is working in accordance with the given specification, including its heat-up time and the temperature it needs to reach.

It is this in-line production test, that causes the glow plug’s tip to take on this grey/blue tone. This colouration is due to the oxidation of the metal, which is accelerated by the high temperature it is subject to during the test, but it does no harm to the glow plug,

“This colouration is due to the oxidation of the metal, which is accelerated by the high temperature it is subject to during the test” nor does it degrade its performance.

Therefore, rather than being something of concern to technicians when opening the box, it should be regarded as a sign of reassurance, because it indicates that the glow plug they are about to fit has been tested and works according to its given specification, and will perform as they’d expect a large OE automotive parts supplier.

Denso’s R&D investment helps it to pioneer increasingly efficient and reliable diesel engines with minimal emissions. Its aftermarket division draws on this expertise, offering a comprehensive, all-makes glow plug programme intended to improve start-up performance with extended post-heating temperatures.

PMM asked Ken Clark, managing director of Rotronics Battery Management Solutions, to give readers an understanding of the importance of maintaining the 12 V battery in an electric vehicle.

Look after the little BATTERY

A

s with traditional internal combustion engine and hybrid vehicles fitted with a 12 V battery, all electric vehicles have a 12 V “auxiliary” battery. The battery technology used in these vehicles are commonly AGM (absorbed glass mat), EFB (enhanced flooded batteries) and can be traditional (flooded) lead acid batteries, or in some cases lithium (LiFePO4) are used.

What may surprise you is that these batteries play a crucial role in managing the functions of the high voltage pack and still require the same maintenance and care practices as ICE vehicles. Improper care and maintenance can lead to acid stratification and sulphation of the battery, reducing its performance serviceable life, resulting in premature replacement and vehicle non-start, as well as an “unhappy driver” experience.

Potential failures EVs experience roadside breakdowns due to “flat batteries” and when it comes to industry statistics, battery failure remains the top attributable factor for all vehicle roadside callouts. Recent roadside breakdown statistics show that 43 per cent of all roadside breakdowns are as a direct result of the starter battery and this includes both ICE vehicles and EVs. Despite the reduction in EVs’ maintenance requirements, these vehicles still have the same challenges, pitfalls and opportunities to maintain, support and replace the 12 V battery going forward.

What’s the purpose of the 12 V “auxiliary” battery in EVs, how can it fail and what can you do to minimise these risks?

The first table gives a brief overview of its role:

What can you do to maintain 12 V batteries?

■ As with all discharged 12 V batteries,

charging is required to restore full power performance and maximise battery lifespan and can be achieved using widely available intelligent chargers: it’s the same straightforward process and no special equipment is required.

■ In contrast, the 12 V EV battery will require a unique diagnostic approach tailored to their application, which will assess available safety power capacity, to power critical vehicle systems.

■ As EVs have no engine to start, traditional

conductance testing is not a suitable measure of battery condition.

■ The development of Midtronics SafetyPower diagnostics platform will accurately measure the available capacity of a 12 V battery.

■ This cutting-edge technology and approach to 12 V “auxiliary” battery testing will provide a precise decision on a battery’s ability to power the vehicle’s low voltage loads.

electric vehicle service strategies, the inclusion of necessary qualifications and equipment to the support their future needs become a key requirement.

■ While aftermarket tailored equipment solutions enabling high voltage battery maintenance are in development (enabling module balancing and cell replacement).

Deployment of the most accurate diagnostic technology for 12 V batteries in electric vehicles is a positive step towards EV service readiness.

■ Unlike electric vehicle traction packs that are relatively reliable and come with up to 10 years manufacture warranty, the 12 V battery is typically backed by a 2-3 year warranty, and can be a simple “win” for aftermarket workshops aiming to keep their EV customers mobile through maintenance and/or replacement of the 12 V battery when the need arises.

■ Getting your workshop “12 V EV ready”

by ensuring you have both the correct means to diagnose and charge 12 V batteries and implementing a proactive testing and charging programme as part of your workshop service plan, will ensure you keep your customers mobile, whilst increasing sales revenues and customer satisfaction.

GLOW PLUGS: A Warmer Winter The winter months are the key selling period for glow plugs and Niterra is working closely with workshops to ensure they do not miss out on any service opportunities for its NGK ignition parts range.

N

GK glow plugs provide over 70 per cent coverage of the 17.3 million diesel car parc in the UK, as well as frequent newto-range launches to ensure popular and new models join the coverage. The components are often noted for their fast start, reliability, and ability to perform in tough cold weather conditions, something which is becoming increasingly important for a glow plug to deliver. As an indispensable part of the exhaust and emissions system they are also essential for maintaining optimum emissions and play a role in preventing damage to related components, such as the clogging of the exhaust gas recirculation valve with excess deposits.

Seasonal peak The winter months become a natural pinchpoint for glow plug demand due to seasonal changes and emissions testing, along with

“As an indispensable part of the exhaust and emissions system, glow plugs are also essential for maintaining optimum emissions”

standard servicing requests. Becca Knight, marketing manager, Niterra UK, said: “We work year-round to provide availability of our highly demanded NGK glow plugs ready for the seasonal peak, to ensure workshops have what they need to maximise their service opportunities this winter. Our Original Equipment quality glow plugs

provide workshops with the precision and performance their customers need.”

NGK glow plugs aim to provide workshops with OE quality performance for their aftermarket customers. In some cases, NGK glow plugs will have been the OE fitment of choice for the application, meaning that the workshop can continue to offer the high quality and performance their customers know and expect by stocking NGK for their servicing.

Niterra also supports the recommendation of replacing a full set of glow plugs if one or two are faulty for best results and good customer service. Not replacing the full set, or use of budget alternatives, can be a false economy for the workshop in the form of returning vehicle faults and declining customer satisfaction. Distributors who select NGK glow plugs can extend that best practice and best results to their workshops this winter.

ELECTRIC Avenue Varta discusses the ongoing relevance of the 12 V battery in EV vehicles.

D

id you know, as well as startstop and ICE vehicles, nearly all EVs (BEV, PHEV, FCEV, hybrids) require a 12 V power supply. As cars become more electrified and autonomous, the traditional 12 V lead-acid battery is taking on a new and challenging responsibility as a critical source of power across the evolving range of EVs. There are an increasing number of electrified vehicles entering the market to support governmental targets of reducing CO2 emissions. Their emergence has intensified low-voltage power demands and is continually redefining the role of the 12 V battery. Enhanced levels of vehicle electrification have driven the 12 V battery to become a safety critical component, particularly if the high voltage battery fails.

An electric car’s high-voltage Li-Ion battery powers the drivetrain and the propulsion system, however not the whole vehicle and not all of its electrical power devices.

The internal electrical 12 V power system with its comfort and critical safety features, is powered by a 12 V battery. It works as a secondary power source for the vehicle’s electrical system and ensures that the car maintains its functionality while driving but also whilst parked and the high-voltage battery is disconnected from the drive train.

Comfort and safety features like lane assist, power steering and the brake booster are handled by onboard smart systems which also draw power from the 12 V system. The same goes for most of the car's monitoring functions, it is therefore essential that a reliable 12 V power supply is in good working order.

Traditional technology Why is lead-acid technology still being used in a modern electric vehicle?

Lithium-ion technology is often considered the successor of lead-acid technology when

it comes to batteries.

However, it is not as inherently robust as other battery technologies and requires continuous monitoring by the battery management system. Overall, it is a very sophisticated technology.

Lead-acid batteries, on the other hand, are known to be both reliable and affordable.

Their wide operational temperature window intrinsically enhances the operational robustness of the entire system. The safety record of lead-acid batteries makes them invaluable for Europe’s future low-emission mobility sector, plus lifecycle analysis of a vehicle’s environmental impact show that lead-acid has a lower impact compared to other technologies.

“It is safe to say that the unique benefits of lead-acid technology will be important to meet growing consumer expectations for safety, comfort, and connectivity,” says Dr. Christian Rosenkranz, from Clarios, the parent company of the Varta brand.

What makes Varta’s AGM batteries many OEMs’ choice for EVs?

Varta’s absorbent glass mat batteries have proven their reliability for many years. It is their sturdy construction, behaviour and inherent safety that makes them the perfect companion in supporting the 12 V electrical system of EVs. Every major car manufacturer is entering the electric vehicle market with battery electric or hybrid electric vehicles. As the world’s leading battery manufacturer, Clarios is the number one supplier to all renowned original equipment manufacturers with its Varta brand.

Its products are fulfilling all OE requirements.

That is why well-known manufacturers such as Mercedes, Volkswagen and BMW are fitting their cars with Varta batteries; in fact over 60 per cent of new vehicles in Europe are being factory fitted with a Varta.

The Varta Silver Dynamic AGM portfolio is designed to be ready for EV and hybrid vehicles, now with added designation to the AGM labelling.

A YEAR ROUND hit

Whatever time of the year, batteries provide profit opportunities, argues Ecobat Battery, but it all starts with testing.

42 DECEMBER 2023 PMM

I

ncredibly, it’s now three years since the country started to emerge from its forced hibernation as the lockdown restrictions imposed during the worst of the Covid pandemic were eased and people started to venture out, only to find that their cars wouldn’t start as the battery was dead, discharged because of the vehicle’s lack of use over an extended period.

At the time, this provided the trade with a real shot in the arm as sales of replacement batteries soared, but now, a second opportunity is beginning to make its mark, as these very replacements are beginning to provide a ripple effect, as many of these are now coming towards their end of their lives. This development is likely to come into particular focus as the nights draw in and the temperatures drop, leaving many drivers to find their battery is faltering, or possibly completely flat.

However, a difficult question that’s been raised on many occasions, is that without drivers experiencing starting problems, how do they know where their car’s battery is in its lifecycle? The answer, which is a subject that has also been raised on many occasions, is to have the battery tested, but realistically, motorists are not going to do this proactively, so it’s down to workshops to put a battery testing regime into practice. This policy is even more important as the seasons change and the

increasing likelihood of some early morning frost or a prolonged cold snap.

Sadly, however, despite it taking just a couple of minutes, workshops rarely do a battery test, which is a wasted opportunity because as Ecobat Battery, the UK’s largest battery distributor, has found, statistically, 27 per cent of the vehicles that enter the independent workshop either need their batteries recharged or reconditioned, and a further 11 per cent need a replacement.

What all this means is that almost 40 per cent of the vehicles they service daily have a battery issue, so it is little wonder that 40 per cent of roadside breakdowns are due to battery failure, which is business lost to independents and gained by the national breakdown services.

“Even when disconnected, a typical lead acid SLI battery will discharge at the rate of 0.1 V per month, which means that a fully charged battery at 12.7 V will be discharged to the point that it would struggle to start an engine in just nine months.”

042_PMM_DEC23.qxd_Layout 1 30/10/2023 09:32 Page 43

Workshop displays So, to encourage and assist workshops to introduce a battery testing culture, Ecobat Battery can, through its motor factor customers, provide them with point-of-sale support material that includes battery testing report cards, counter displays, A4 leaflets and A2 posters, which are available in a choice of Lucas, Exide, VARTA or Numax branding.

As well as stating why they shouldn’t be overlooked by workshops, it’s worth exploring why batteries discharge, particularly in cold weather and ultimately, why they fail.

Even when disconnected, a typical lead acid SLI (starter/lights/ignition) battery will self-discharge at the rate of 0.1-volt per month, which means that a fully charged battery at 12.7-volts will be discharged to the point that it would struggle to start an engine (11.8-volts), in just nine months.

This natural discharge process is obviously exaggerated when the battery is connected because it is the only source of power to the

vehicles electrical system when the engine isn’t running, so its numerous electronic devices – clock, alarm, remote locking mechanism etc.

– all constantly draw power, further increasing the rate at which it discharges.

Opening and closing the vehicle without driving anywhere puts more pressure on the battery as it can draw as much as 50-amps to do so; should there be a parasitic drain because of a problem somewhere in the vehicle’s electrical system, the issue is further exacerbated.

When these real-life scenarios are combined with cold weather however, the pressure on the battery moves to an entirely

new level because, even without these ongoing issues, when the temperature drops to freezing, the battery can lose up to 35 per cent of its power, which is why cold weather shows up battery problems so intently.

When it comes to why most batteries reach their end of life it is generally due to a process called sulphation, which is a chemical reaction that takes place in the electrolyte within the battery when the voltage drops to 12.4 or below, which causes lead sulphate crystals to build up on the lead battery plates. This reduces the battery’s capacity and cranking potential and signals the beginning of its demise.

These combined effects along with reduced car usage means that whatever the weather, the future remains bright for the replacement battery sector.

Why do we SERVICE cars?

Wynn’s discusses the importance of regular vehicle maintenance and provides some suggestions on how you can ensure customers’ cars work as efficiently as they can.

T

he most common operation in a garage is maintenance. Good maintenance work is essential to:

■ Extend the life of vehicles.

■ Avoid costly repairs due to wear and tear

and contamination of parts such as EGR valves, particle filters, injectors, combustion chamber, turbo, etc.

Reasons for engine pollution Vehicle pollution is unavoidable, although it is possible to extend the life of vehicles with maintenance work.

Fuel quality: Today’s fuels do not come entirely from petroleum. Their formula is a blend of biofuels to make our vehicles more environmentally friendly. However, they also generate more waste and deposits that over time reduce performance and cause costly car breakdowns.

Anti-pollution systems: The various anti-pollution regulations set by the EU have meant installing complex systems such as EGR valves, particulate filters, catalytic converters, and, more recently, the SCR system. Such systems reduce environmental pollution in exchange for retaining it inside the vehicles.

Driving styles: Frequent city driving on short journeys, with engines that do not reach the correct temperatures, frequent accelerating and braking, and low engine speed driving accelerate internal pollution and engine wear.

The solutions to eliminate contamination The maintenance recommended by car manufacturers – oil and filter changes – can, Wynn’s argues, lead to dissatisfaction on the part of drivers because the engine generally does not show better performance after maintenance. Even if the driver decides to check the oil level after the change, he would see that the sample would come out black, just like the old oil.

With this in mind, the manufacturer argues that the use of additives during routine maintenance may reverse this view. Additives restore the original performance of vehicles and thus avoid costly repairs.

Wynn’s recommends using Wynn's Total Action Treatment Diesel for diesel engines and Wynn’s Total Action Treatment for petrol engines. Also, use an Oil System Cleaner to clean the internal engine before adding the new oil.

Potential benefits from engine additives: Cleans the injectors Restoring the injector spray patterns allows better fuel delivery.

Cleans the combustion chamber Removing deposits from the piston crown, increasing cylinder volume, and improving combustion efficiency.

Reduces clogging of the EGR Cleaning the fuel system and restoring combustion efficiency reducing egr deposits.

Cleans the turbo Additives active after combustion, allowing cleaning of the turbo variable vanes and turbo wastegate.

Cleans the cat/DPF Additives active after combustion, cleaning the Catalytic Converter and Gasoline Particulate Filter and aiding regeneration of the Diesel Particulate Filter Potential benefits from using an oil system cleaner: Remove deposits and lacquer from the oil system.

Restore cylinder compression restoring vehicle performance.

Allow the new oil to do the job it is designed to do.

Protect engine components and reduce wear.

ELECTRIC Dreams or DIESEL Demand?

Mike Schlup, managing director of Kalimex, UK distributor of JLM Lubricants, argues that the rumours of the death of the diesel engine have been greatly exaggerated.

T

he initial fanfare for electric vehicles has dampened with recent automotive surveys pointing to motorists not looking to switch to EVs for many reasons; not least range anxiety, the cost of EVs and the rising cost of living. In fact, motorists are not replacing their vehicles full stop. A recent survey by Cazoo found that 8 out of 10 motorists plan on keeping their car for longer. Added to this is the fact that second-hand ICE cars will be unaffected by the 2035 ban, and you can see why the second-hand market will remain buoyant with well-maintained vehicles in demand.

It points to the trusty workhorse – the hallmark of a diesel vehicle – being in big demand long after the 2035 deadline.

Existing owners will want to keep theirs in good repair for longer while the second-hand searcher will be keen to grab a good diesel deal before stocks really do run dry.

What part does the independent technician play in all of this?

The independent professional motor mechanic plays a crucial part in maintaining the health of a diesel vehicle especially the DPF because we know from case studies of DPF specialists across the globe that the technician holds the keys. Motorists are only aware of the DPF on their vehicle when the warning light comes on.

But today’s technician has to keep repair bills reasonable given the reluctance for vehicle servicing. Take a blocked DPF for example.

Dismounting it for off car cleaning or replacement is time consuming which all adds to the final bill. But quality additives inject chemicals into the DPF directly, breaking down the soot without the need to expose the DPF to the potentially damaging high temperatures of a forced regeneration. Fewer technician hours, smaller bill, great result.

“Motorists are only aware of the DPF on their vehicle when the warning light comes on.”

46 DECEMBER 2023 PMM

JLM Lubricants supply a range of trade tested and trusted DPF products used in over 45 countries from the UK to Australia, the Netherlands and America. This includes a pro-only toolkit that will clean the most badly blocked DPF without dismantling it.

Some products can be sold to the customer so they can play their part in keeping the DPF in good condition between workshop visits. It’s a win for everyone. The technician uses tools and products that reduce workshop time, and they build an additional revenue stream promoting best of breed DPF products to their customers.

JLM Lubricants DPF products for your workshop Diesel Particulate Filter Cleaner ■ Contains a high percentage of active ingredients including Cerium and Platinum which works at lower temperatures. Cerium also has environmental benefits because it produces lower emissions than iron, including dangerous emissions (Cerium and Platinum help extend the life of the DPF core by helping carbon deposits in the DPF to burn off at a lower temperature around 400°C compared to iron-based formulas which artificially elevate the DPF temperature and produce more ash deposits.)

■ Cleans the soot filter and reduces air polluting particulate matter hydrocarbons, carbon monoxide and soot emissions.

■ Reduces soot and fine dust emissions by up to 25 per cent.

■ Significantly reduces likelihood of clogging and increases DPF service life.

■ Use at first DPF warning light.

Raising your EV game!

Maha offers advice on EV adaptors for two-post lifts.

A

s the automotive aftermarket takes strides toward electrification, the need for specialised equipment and tools to accommodate EVs is becoming increasingly urgent. As such, one important piece of equipment that requires adaptation for EVs is a two-post lift.

The rise of EVs has brought about a transition in workshop services. Unlike traditional internal combustion engine vehicles, EVs have specific components that demand unique considerations when it comes to servicing and repairs. An EV battery pack, for example, adds weight and safety concerns that need to be considered before conducting any work on the vehicle and component.

Two-post lifts and EV maintenance Two-post lifts have long been a staple in workshops, offering technicians easy access to the underside of a vehicle for various tasks, from oil changes to suspension repairs; however, as the automotive landscape evolves, so must the tools involved.

Maha has long campaigned for the use of the correct adaptors on two-post lifts, citing

the wrong use of wood rather than the correct method of using either a 200mm sleeve or Ushaped adaptor, like an anti-slip sleeve, that fits either side of a chassis. EV adaptors are just as important; they bridge the gap between a lift’s arms and an EV’s unique frame, ensuring secure and safe lifting – reassuring for both technician and vehicle owner.

The equipment supplier offers a range of ATS manufacturer-specific EV lifting adaptors for the likes of Audi, BMW, Mercedes and Tesla.

Key considerations when choosing EV adaptors: Weight capacity: EVs tend to be heavier than their ICE counterparts due to the weight of the battery pack.

When selecting which adaptor to use, therefore, it is important to choose one that can support the specific EV models technicians will be working on.

Frame contact points: Adaptors should provide sufficient contact points with the EV’s frame to distribute weight evenly, thus, reducing the risk of damage to the vehicle during lifting.

Safety features: Locking mechanisms prevent accidental lowering and secure the vehicle while it is raised.

Adjustability: Some EVs have varying frame structures. Maha’s adaptors offer flexibility to accommodate different vehicle configurations.

Benefits of using EV adaptors: Safety: Adaptors designed for EVs ensure that the lift arms securely and safely engage with the vehicle’s frame, reducing the risk of accidents or damage during maintenance.

Efficiency: EV adaptors make it easier and faster for technicians to position and lift EVs, thus, improving overall efficiency in the workshop.

Versatility: While it is important to be wary of choosing the correct adaptor; in fact, many are designed to work with multiple EV applications, making them a versatile addition to a workshop’s toolbox.

he right tools can make all the difference between a smooth, efficient job and a frustrating, time-consuming ordeal. Whether mains charged, cordless or operated by hand, tools truly are the backbone of any car repair workshop. From tightening nuts and bolts to working with hoses, wiring, and other intricate components, the precision and reliability of these tools can significantly impact the quality of work performed by mechanics.

How to choose So how do you choose the best tools for the job? When it comes to hand tools, picking the right tools comes down to many factors, but the main ones should be the quality of the manufacturing process and the specialisation of the tool, in other words, whether the tool designed for a specific job or purpose. Trying to use generic pliers for some jobs may result in frustration and loss of time, not to mention potential damage to the parts of a vehicle. In terms of quality, look for high-grade special tool steel, forged and oil-hardened for added strength and durability. Safety is also important – if you work with electric vehicles, then you will need to choose VDE rated tools.

Delphi is seeing ever more technicians interested in its EV training offering and has increased its focus on that complicated colossus of the battery-powered world: Tesla.

D

elphi offers face-to-face training from its Titan 10 facility in Warwick. The focus is on future technology with vehicles, service equipment and test rigs available for technicians seeking ‘hands on’ experience.

Nearly three quarters of delegates attending the training courses are following a defined CPD training pathway, mapped to industry-recognised IMI qualifications.

Available paths include IMI service, fast- fit, service/diagnostic and master technician assessments. Each of the pathways provides between four and seven modules which are one or two days in duration. IMI accreditation is then dependent upon completing an additional assessment day afterwards.

The Delphi Academy gives a convenient way to enhance skills and knowledge without the challenges of attending physical training.

There’s a training needs assessment which includes a series of questionnaires and online ‘practicals’ before suggesting modules to complete tailored to that user. Hybrid and electric vehicle training is the perfect example of the benefits of a true blended learning experience.

For the more advanced EV course we provide six hours of online pre-learning on

electrical systems to try and get the foundation knowledge of electrical principle to then build upon in the training centre.

Delphi’s combined e-learning offering comprises 16 courses on vehicle electrics, hybrid and EV alone. In all, there’s a total of over 100 modules varying in length from a couple of minutes to nearly an hour each.

EV training growth Four of the five most popular training courses relate to EVs and hybrids, perhaps not surprising given how registrations of electric vehicles are surging. According to SMMT figures, 2022 saw UK registrations of hybrid and EV cars exceeding the combined volume of petrol and diesel engine cars for the first time.

Delphi’s one day hybrid and electric vehicle level 3 course is designed to support technicians to work safely on high voltage systems, as well as petrol and diesel hybrid systems.

This would enable a technician to disable and power up the high voltage system safely to change components. All its EV training carries IMI TechSafe recognition too, demonstrating they are fully prepared to be working on EV. Beyond this, there’s a two day level 4 course which covers diagnostics. With the power off, fault finding can be difficult so this course goes much more deeply into diagnosing live high voltage systems including high voltage battery repairs from different manufacturers.

Tesla suspension repairs For those garages opting to get involved with EV repairs now, Tesla work can often form a surprisingly large part of the requirement.

Delphi has recently investigated a recurrent issue on the suspension system of the Tesla Model S. A Tesla technical service bulletin (TSB) relating to this fault (SB-1731-006) stated: ‘some Model S and Model X vehicles might have been manufactured with front suspension lower fore links that do not conform to Tesla’s subjective specifications for strength. In the event of link failure, the tyre might contact the wheel arch liner, but the driver can still maintain control of the vehicle.’

Earlier this year, to support aftermarket repair solutions, Delphi added a complete front suspension solution for the Tesla model S to the range, including all upper arms, lower arms, and anti-roll bar links.

Working with Tesla Also in 2023, to coincide with the release of Tesla Model S and Model X coverage on Delphi’s BlueTech VCI diagnostic tool, an eleven-part course was added to the Delphi Training Academy. The course modules cover vehicle identification, data, and parts ordering as well as diagnostic hardware, connection, and common jobs.

“Everything is a little bit different when it comes to Tesla,” said Philip Mitchell, workshop solutions manager at Delphi. “But garages needn’t turn away these cars, they just need to understand how they’re different.”

Tesla’s browser-based diagnostic tool requires technicians to correctly configure a laptop or PC for vehicle connection. Further difficulties arise after successful connection

as Tesla’s distinctive IT-based jargon used within the tool can be problematic. The new e-learning course includes step-by-step video guidance, walking technicians through what can otherwise be a frustrating and time-consuming diagnostic process.

“The first stumbling block workshops face is knowing exactly which model they’ve got,” said Philip. “Knowing if it’s a Model S or Model X isn’t enough because they all use different processors and the method of vehicle connection will depend on which processor it has.

“And then you’ll have to get through a layer of Microsoft security if you want to use Tesla’s browser-based diagnostic tool.

Unless you correctly configure your computer beforehand, all vehicle communication will be blocked and you won’t be able to connect to the car.”

An exam completes the Tesla module with a Delphi certificate and IMI continuing professional development credit for those achieving a 70 per cent pass mark or higher.

As with all Delphi Academy modules, the Tesla content is presented in a user-friendly

format with multi-media learning methods including interactive technical articles, videos and simulators for all levels of ability.

Step-by-step Tesla repairs Last but not least, Delphi’s ‘Masters of Motion’ hub – only launched at the start of this year – already provides ‘how to’ videos for specific Tesla repairs covering: ‘How to bed in the brakes on a Tesla Model S’ WWW.RDR.LINK /ABD020

The RIGHT TOOLS to tackle EVs

A

s the electric vehicle market experiences unprecedented growth, with pure electric cars seeing the biggest increase in new-car registrations in the UK during July 2023, accounting for 16 per cent of the market share, it has never been more important to invest in appropriate tools and training.

The latest statistics from the SMMT further support this, predicting that by the year's end, a new battery electric vehicle (BEV) will be registered every 50 seconds, and this rate is expected to increase to one in every 40 by 2024.

Tool specialist Sealey offers PMM readers its top tips on working efficiently and safely on electric vehicles.

Changing landscape The surge in EV popularity is a testament to the shifting landscape of the automotive industry. With concerns over climate change and the need to reduce greenhouse gas emissions, electric vehicles have emerged as a pivotal solution. Governments worldwide are introducing aggressive policies to encourage EV adoption, offering incentives and imposing stricter emission standards. As a result, consumers are increasingly turning to electric cars, and this trend is set to accelerate.

In this rapidly evolving EV landscape, the role of electric vehicle servicing tools and training cannot be underestimated. Here’s why they are crucial for both automotive professionals and the industry as a whole.

SAFETY FIRST Safety is paramount when working with high-voltage EV systems. Tools and training equip technicians with the expertise to handle electric vehicles safely as they learn how to identify potential hazards, follow strict safety protocols, and use specialized personal protective equipment (PPE) to minimise risks.

Sealey continually strive to develop new and innovative tools and equipment designed to keep technicians safe whilst servicing these vehicles. Products include high-voltage electrician’s gloves, an electrician’s safety mat, and a highvoltage rescue pole.

COMPLIANCE WITH REGULATIONS As the EV market grows, governments are implementing regulations to ensure the safety and quality of servicing.

Technicians who have received proper training and use approved tools are more likely to comply with these regulations, avoiding legal complications and safeguarding their reputation.

Any vehicle being worked on should be placed in an exclusion zone to create a secure working environment. The HP55K1COMBO is ideal for this purpose, as the post and chain kit and high voltage warning signs notify others of the potential danger, preventing them from entering the work area.

54 DECEMBER 2023 PMM

054_PMM_DEC23_Layout 1 30/10/2023 09:55 Page 55

STAYING COMPETITIVE The automotive industry is evolving rapidly, and those who adapt to new technologies are more likely to thrive. By investing in electric vehicle servicing tools and training, automotive professionals can position themselves as leaders in the market, attracting a growing customer base and staying competitive in the long run.

When working on hybrid or electric vehicle systems, a category III analyser or voltmeter is vital.

The circuitry inside the unit is built specifically to safely cope with the high voltages and currents found in this type of vehicle.

Sealey’s TA320 is category III and conforms to EN61010. For further protection from the risk of electric shock, VDE-approved tools must be used. The company supplies a wide range of tools insulated to VDE and EN 60900 standards, including the comprehensive AK7938 3/8 in. Sq drive and AK7939 ½ in. Sq drive tool kits.

Creating a better environment Beyond the economic and safety benefits, servicing electric vehicles contributes to environmental sustainability. As more vehicles transition to electric power, proper maintenance and repair ensures that these vehicles remain on the road longer, reducing the need for new manufacturing and the overall impact.

The burgeoning electric vehicle market demands a proactive approach from automotive professionals. With electric cars becoming increasingly popular, investing in the right tools and training is essential for ensuring the safety and success of technicians and the industry as a whole. As the EVs increase, embracing these changes is not only responsible but also a strategic move for those in the automotive service sector.

We would like to thank our readers who remain loyal and we hope you agree that this year’s PMM Awards represents the best selection of articles we’ve published yet. We would also like to thank the many companies who supported us both editorially and commercially over the past year. Your support is what enables us to put together the best magazine we can each month, something our readers will no doubt thank you for as well.

For now, let’s celebrate what makes this industry fantastic and raise a glass to the winners! Here, news and products editor Freya Coleman takes you through the past year.

BEN JOHNSON ACTRONICS As good as new Kicking off this year’s awards is ACtronics with an article in which Thjs Jasink, the company’s COO, explains what goes into every remanufactured part.

From diagnosing and removing the part, made harder by the complexities of modern vehicles, all the way through to the final inspection where the part has to pass an automated script and a visual quality control. The article also touches on how car manufacturers are increasingly encrypting components which makes it more difficult to replace them and why this might be an argument in favour of remanufacturing. With sustainability being a hot topic both in and out of the industry this year, it’s no wonder this article has made the list.

Troubleshooting issues Those of you who diligently read through the magazine every month (and I’m sure that’s a lot of you!) will have observed that in every one of our 11 issues a year we run a feature called troubleshooter where a diagnostics expert gets to the bottom of a vehicle issue. One of the most popular of these articles in 2023 was written by Ben Johnson for the July/August issue.

Inside, follow along as he goes from watching a BMW X5 get dragged into his workshop on dollies after the appearance of multiple warning lights, to the diagnosis of a failed BDC and a change of battery that brought that car back to some semblance of normality.

With many common issues in cars being covered in our troubleshooter feature, including Ben and his work on BMWs, it’s clear to see the value of this feature and why it continues to be amongst the most popular with our online audience. After all, sharing diagnostics solutions IS caring.

BREMBO ‘Braking’ point

BOSCH Making ‘ESI’ work of diagnostics If you’ve been reading PMM for a while you might remember when we first ran an in-depth guide to Bosch’s KTS diagnostics software, ESI[tronic] 2.0. With how fast technology is moving these days, we thought it would be a good idea to revisit the guide with Bosch and find out what has changed. The first instalment, which kicked off in the September issue, was all about finding the right vehicle which is key to accessing all the tabs you need to get your job done. Catch up on the ongoing series in each month’s issue.

CASTROL

As you might expect, the PMM team is privy to a lot of rumours on the aftermarket grapevine during our travels, especially surrounding how the industry might change with the shift to EVs. One of these rumours was that EVs need to use brakes less than ICE vehicles. So, we turned to brake manufacturer Brembo which was there to set the record straight.

The company explains that even though EV brakes are used less due to the regenerative braking system, leaving braking actions up to the electric motor itself, this actually leaves them open to added corrosion. Other challenges outlined in the article mean that the brakes of electric vehicles need to meet the following requirements: corrosion resistent, silent operation, lightweight design and reduced residual torque. To combat these requirements, the Italian brake manufacturer has released the Brembo Beyond product line, the company’s replacement range tailored to improve EV driving.

With the future certainly looking to be electric, whether this is by 2035 or not, it’s great to see companies gearing up to help workshops in this somewhat turbulent transition.

WWW.RDR.LINK /A BD028

‘Oil’ about EVs Another example of a company looking to the future, and more importantly looking at the sector’s electric future, is this next article from Castrol. Now, you might be thinking that as the UK shifts over to electric, with some predicting that 80 per cent of passenger cars on our roads could be EVs by 2050, oil might be left behind with ICE vehicles, but this isn’t the case. In fact, Castrol has been working closely with car makers and motorsport teams to develop its latest range of EV fluids.

The range currently consists of Castrol ON EV transmission fluids, thermal fluids, and greases. The ON EV transmission fluid's D1 and D2 variants suit a wide range of EVs, aiming to help extend the life of the drivetrain system and enabling EVs to go further on a single charge. This reflects the company’s aims to be a net zero brand by 2050 or sooner – an ambitious goal if ever there was one for an oils company.

DAYCO Online traction When articles are published on the PMM website, links are posted on our Facebook page which makes it a great place to stay on-top of the latest in the industry. It’s also a great place for Facebook members and/or PMM readers to discuss the content of the article. This definitely happened with this next article from Dayco which discusses some of the wider issues of the timing belt replacement on Ford’s 1.0 litre EcoBoost “Fox” engines. Commenters on our Facebook discussed their shared experiences and frustrations with issues faced in replacing the belt on Ford engines, proving the need for our online guides!

It’s great when our readers get involved online and we love to hear from you, and this is a great example of technicians engaging in the content we produce, hence why this article from Dayco has made the list of winners this year. Also, belt in oil Ford engine articles are very popular amongst our readers on the website, so we are grateful for Dayco for providing them!

DELPHI One step at a time Keen PMM readers will have noticed that halfway through the year our ‘Tech Tips’ feature transformed into the ‘CPD Zone’, standing for ‘continuing professional development’.

This is because the magazine is now CPD accredited! One of the most popular CPD articles was from the June issue and written by Delphi who supplied a step-by-step EGR valve replacement guide courtesy of its Masters of Motion hub for independent garage technicians. Part of its success was down to the helpful images that accompanied the in-depth instructions.

So, next time you’re reading through the feature, make sure to scan the QR code at the end of the last article which will provide you with a downloadable certificate which can be used as part of your ongoing CPD record. With Delphi contributing regularly to the CPD zone this year, and the buzz it created amongst our readers, it’s clear to see why this technical article made the podium.

WWW.RDR.LINK /A BD031

FEBI Building the suspense...

Also part of our CPD Zone was this next article from febi, providing PMM readers with a guide on some common issues with the suspension system on the Ford Focus, a popular car amongst drivers but also one of the most popular vehicle models visiting workshops for repair work. So, it is well worth knowing the ins and outs of and it’s clear to see why this article was so popular amongst our online readers! Upon completing the article, readers will learn helpful tips such as how when the anti-roll bar links are worn, they can produce a rattling noise symptom while being driven on bumpy roads AND how to fix this.

LUCAS OIL LIQUI MOLY Read ‘oil’ about it In this next article from Liqui Moly, head of application technology Harry Hartkorn explains how the standard oil change service provided by garages could actually be turned into a lucrative transaction. One example of how this can be done is through grouping services into packages, tailoring them to the vehicle and the budget of the customer. The example used here is the grouping together of cleaning the oil circuit, the actual oil change and extra wear protection. If this helpful advice wasn’t enough, the article then goes on to suggest the best Liqui Moly products to use with each of these steps, such as how the oil circuit can be cleaned with the Pro-Line Engine Flush.

At PMM, we often see a trend of very skilled technicians under selling themselves or missing out on business opportunities, so it’s great to be able to spread news of upselling opportunities from brands such as Liqui Moly. Furthermore, with the cost-of-living crisis still rearing its ugly head, tips on making more money in the workshop, whilst still helping your customer, are more useful than ever.

Take a pit stop I don’t know about you, but with how hectic life can be I think it’s nice to take a breather every now and again which is the goal of our Pit Stop feature which sits each month sandwiched between articles on tech tips or business guidance. This page from the magazine which usually features a quiz and a joke or two written by yours truly, was given a makeover this year thanks to our next winner: Lucas Oil. This revamp included a snippet of what life on the racetrack is like from Lucas Oil-sponsored driver Tony Lynch. Over this set of six articles, a real insight into the world of rallycross driving was revealed to us such as what happens when a broken fuel pipe occurs halfway through a heat or how to bounce back for a race on a Sunday when you went into a roll at 3pm on a Saturday. I’m sure you’ll agree, there’s some pretty thrilling stuff there and it’s so interesting to get an insight into the work behind the races.

Not surprisingly, there seems to be a lot of overlap between technicians and those interested in competitive driving, so it’s no wonder these set of articles have made the list of winners this year.

MOTUL

SOUTHEAST COAST AMBULANCE SERVICE

Modern oils for classic cars

Vehicle repair on the front line

Due to the popularity of Motul’s classic car article we ran back in 2022, we thought it would be a great idea to introduce a whole new classic car feature to the magazine. Sitting proud in this new feature is this next award winner Motul, sharing its insight on the classic car market.

With this lubricant company being more than 150 years old, who better to shine a light on the increasing opportunities in the classic car market?

This article covers lubricants you can use on pre-war cars, all the way through to so called “youngtimers” which encompasses cars from the ‘80s, ‘90s and even the noughties and reflects the growth within the classic car market. Furthermore, with the UK car parc increasing in age and people holding onto the cars longer, we might see even more vehicles going from ‘banger’ to ‘classic’ territory.

Prompted by a discussion at our Mechanex trade show last year with Ross Crook and John Giles, area workshop managers for the NHS’ Southeast Coast Ambulance Service, PMM’s editor Kieran Nee went to visit the service’s Make Ready Centre in Banstead.

Now, you might imagine that your workshop has little in common with these centres that keep the NHS’ fleet up and running but Kieran expressed how it was interesting to find out that many of the pressures and challenges faced by the independent sector are also affecting the NHS. For example, does struggling to retain staff and failing to find parts sound familiar to you?

Did I mention yet that we have a podcast? You can listen to the interview in full in the episode aptly titled ‘NHS Visit’.

SCHAEFFLER One in a million Earlier this year, Schaeffler announced it had crowned its first Bonus Point Millionaire which came following a promotion run in the PMM magazine to celebrate its 10year anniversary. The winner, chosen from a random draw taken from the workshops who had purchased Schaeffler products between February and April, was revealed to be Markhams Garage which has an impressive 100 years of history. In this next article, therefore, PMM finds out all about the garage’s rich history including my personal favourite – the introduction of the MOT test in 1960. The test was originally only obligatory for vehicles over 10 years old and only covered a basic check on brakes, lights and steering. How times have changed!

SEALEY The tools for success When tools are rusted, dulled or are missing parts, completing the jobs you need to as a technician are made harder, longer and more dangerous. Therefore, to extend the lifespan of the tools you have invested in it is imperative to properly take care of them. In this next article, tool specialist Sealey gives its advice on maintaining and looking after the tools in your workshop. This includes buying proper storage for your tools and investing in rust removers and aerosols that help with corrosion protection. Making these investments can help save you money in the long run, which I’m sure is what all technicians want.

Moreover, in a time of sustainability, it’s much better to invest and look after what your garage has, than to keep buying new tools.

STRAIGHTSET An MOT makeover The MOT has become a hotter topic than ever over the past year, with the government proposing a first test at four years and Garage Hive’s Alex Lindley revealing that there has been a 3.3 per cent FALL in MOT testers but 13.5 per cent RISE in MOT demand at The Blend. Therefore, the pressure on our MOT feature has been greater than ever but Straightset certainly delivered with its article from the April issue which provides readers with some advice on installing or upgrading their MOT equipment.

This includes choosing the right equipment such as an MOT lift, a jacking beam, a connected and approved brake tester, a headlight tester, an emissions analyser and an MOT accessory pack. Tips such as making sure your chosen emissions analyser is Euro 6 compliant and has MTS connectivity and the advantages of a combined gas and smoke analyser are packed inside this winning article, making sure your garage is carrying out MOT tests efficiently and safely.

WOMANIC Women in the workshop Rounding off this year’s PMM Awards 2023 is the lovely woman behind Womanic: Louise Baker, an interview where we try to get to the bottom of why more women aren’t picking up a spanner and getting their hands dirty. This was originally conducted for the podcast which you can listen to now, but it was too good not to include some highlights in the magazine as well. My personal favourite surrounding her advice to anyone wanting to pursue a career in a workshop: “My advice is to just do it. Don't think about it, just do it. Don't procrastinate, if you want to do it and you love it, and you enjoy it, no matter what it is, whether it's cars, whether it's anything, if you've got an interest in it, just do it. Don't let anyone tell you that you can't do it.”

And what a great message to end this year’s awards on!

Ride or Die Tool

Inspired by Louise speaking about her affinity for hammers, Liam, an avid reader of the magazine, wrote in to express what his ‘Ride or Die’ tool is!

ESPECIALLY DURING THE BRUTAL WINTER MONTHS HERE IN THE UK, AND “ AS THE DAYS GET DARKER, MY FAVOURITE TOOL HAS TO BE MY HEAD TORCH. I LOVE BEING ABLE TO HAVE MY HANDS FREE TO WORK ON WHATEVER VEHICLE IS IN FRONT OF ME, AND BE ABLE TO SEE IT PAST 4PM IN THE WINTER! MY ANSWER MIGHT CHANGE WHEN THE SUN COMES OUT AGAIN.

IN THE WORKSHOP? with Freya Coleman

Green can be seen Supertracker have updated the STR1 laser half cab and trolley to feature green lasers.

The use of green lasers is reported to improve the visibility, precision and clarity of the laser line. The human eye is inherently more sensitive to green light due to the photopic response, a phenomenon where the eye's peak sensitivity falls around 555 nanometers, which coincides with the wavelength of green light. This heightened sensitivity allows green lasers to appear brighter and more visible than red lasers to the human eye.

The STR1 Supertracker have now brought this enhancement to wheel alignment, offering laser wheel alignment systems with green lasers. The STR1 green laser wheel alignment system is available as a wall hung solution as a space saving option or on a trolley as a mobile solution. Both of which are designed in a neutral grey and black, which aim to complement the other equipment found in a workshop environment. This design update offers customers a sleek look, as well as brings together the company’s full alignment range into one uniform, straightforward design. Now supplied with a 9V battery, for increased battery life and supplied as standard with hangers to fit up to 24” wheels, with the ability to easily and accurate measure toe and thrust angle.

Green light advantages Green lasers are visible in a much wider range of light conditions, meaning it should be effective for all year-round work, indoors and out as well as they can travel over longer distances. They also offer clarity and precision due to the brightness, all important factors in environments requiring pinpoint accuracy. This innovation led to an increase in popularity of green lasers in many applications such as construction, installation, surveying, medicine, entertainment, technology.
