A SOLUTION FOR FORD DPF REGENERATION ISSUES

First Line has issued advice to technicians looking to solve a diesel particulate lter (DPF) regeneration issue on popular Ford vehicles caused by failing OE pressure hoses.

The third-generation, 2.0 litre TDCi–engined Ford Mondeo, and associated S-Max and Galaxy derivatives produced from 2007 to 2014, feature a DPF coated with a platinum-based catalyst. The catalyst lowers the temperatures needed to start burning the carbon build-up in the DPF and is designed to last about 120,000 miles.

The Ford DPF is monitored by a Di erential Pressure Sensor that checks for conditions where the lter may become overloaded. However, the sensor is attached with rubber hoses that can fail due to high temperature uctuations and cause incorrect sensor readings.

By exceeding the threshold for conditions in which the DPF may become overloaded, a Diagnostic Trouble Code (DTC) of P2002: Particle Filter E ciency Below Limit may be thrown, causing technicians to consider expensive and potentially unnecessary DPF replacement.

If the rst DTC is cleared by the technician and the car is driven away, but then exceeds the threshold at which the pressure sensor deems the DPF to be overloaded for a second time, this can disable the EGR valve and put the car in limp home mode, as the DPF is likely full and may now need to be replaced along with the any other components that have led to the failure.

Global Sales Director at First Line, Kevin Neaverson, said: “It is extremely unusual that a DPF will simply fail on its own, as it is just a lter. As with many issues that appear to be caused by a DPF that is full or not regenerating, it’s often a symptom rather than the cause. At this stage, the true fault needs to be identi ed so that the DPF can regenerate itself and continue to do its job.”

First Line strongly recommends that if the vehicle is reporting engine codes relating to the DPF or Di erential Pressure Sensor, for example: P2002, P2453, or P2452, then there is a possibility that the Di erential Pressure Sensor Hoses are the cause and require replacement.

The OE rubber hoses can become fatigued, hardened, brittle or scorched, which leads to the hoses failing, causing incorrect readings to the Di erential Pressure Sensor.

“By inspecting the pressure hoses rst, technicians can save the vehicle owner timely and costly repairs. This is simply a 45-minute job that requires the vehicle to be high on a ramp, so that access to the Di erential Pressure Sensor can be gained via removing the sub-frame cross brace as it is located just behind the engine,” Neaverson comments.

First Line’s pressure pipe (part FEH1000) replaces the OE reference 1440559 or 6G915H241AA and o ers a durable pressure hose that can withstand the highly uctuating temperatures and harsh working conditions, helping prevent failure and DTCs relating to DPF failure.

COMMON-RAIL DIESEL RANGE

Denso says that despite the growth in hybrid and electric vehicles, diesel powered cars and light commercial vehicles still make up a huge part of the European vehicle parc, so original equipment replacement components remain of great importance. To ensure diesel engines run as e ciently and reliably as possible, many rely on highly engineered and incredibly precise diesel injectors, served by equally hightech fuel pumps.

DENSO Aftermarket has introduced an additional seven common-rail injectors, as well as seven common-rail diesel fuel pumps, into its range. These 14 items cater for 114 applications, including the Mazda 2/3/CX-3, Mitsubishi L200 and Toyota Hilux. These additions can be found in the company’s E-catalogue www.denso-am.eu/ catalog/pv and via TecDoc.

SNAP-ON SOFTWARE UPGRADE

Snap-on says that when technicians update their diagnostic tools with the latest software release, they can be con dent that their diagnostic tool will perform smarter xes that lead to complete repairs and satis ed customers.

New coverage highlights include: 2022 model year updates for all available makes; expanded code scan and clear codes for the model year 2023; new 2022 models including BMW 2 Series Active Tourer, HR-V-EV (Electric), PSA C5X, Renault Zoe Ph2 and Vitara Hybrid; coverage highlights include 2021 and newer Hyundai Elantra, Santa Fe and Sonata front-view camera calibration; Mazda 2022 MX-30 functional tests and special functions for the powertrain control module, instrument cluster and adaptive front lights; Ford 2021 and newer, over 35 new variants with added special functions including ADAS and many more.

Snap-on claim to be the rst to provide access to Nissan’s secured vehicles in Europe, direct from the scan tool. The 23.2 software bundle has also added Ford to their portfolio providing access to the vehicle right from the scan tool.

BOOST FUEL ECONOMY AND REDUCE NOISE!

Delphi Technologies introduces new bi-metallic, high-carbon alloy brake discs, delivering a 15% weight reduction compared to a single, fully cast-iron disc – helping to improve fuel e ciency and reduce vibration and noise.

The parts feature its new component coating, Magni, engineered to deliver superior corrosion protection from a single layer and is said to further enhance the appearance of the nondrilled, drilled and slotted discs sporting the coating.

Applications included in the initial launch have focused on some of the most popular BMW models. The range is planned to expand soon with applications currently in development for Toyota, Mercedes, Tesla, VAG, Jaguar Land Rover.

Workshop bene ts

By choosing these coated discs with many bene ts for their customers, the workshop can improve servicing upsells and increase average invoice values. The discs have no oil- lm; therefore, they do not require cleaning before installation, and they come with xing screws for a fast- t solution out of the box.

“We chose this coating for its ability to enhance corrosion protection while not compromising the other high performing aspects of these brake discs.” comments Laurence Batchelor, Delphi Technologies Global Chassis Lead. “This new range

In a corrosion stress-test, comparing a BMW OE coated disc vs a Delphi Technologies disc with the Magni coating, the Delphi Technologies disc far outperformed the OE disc; taking 240 hours to show evidence of corrosion compared to the 120 hours of the OE disc.
