NEW DPF AND TURBO BOOST TEST KIT From Diesel Help Australia
HPP Lunds has a range of tools under its Rock Tools brand
As well as diesel diagnostics training, Diesel Help Australia provides diesel diagnostic support to more than 200 trade members in Australia and NZ.
Every workshop has disappearing tools – they are the ones most often used and so they are easily misplaced or broken.
Clinton Brett, the Founder and Trainer of Diesel Help Australia, and his team witness a high level of diagnostics involving DPF and turbo faults.
That is not just inconvenient, but it also holds up too many simple jobs and turns them into time wasters, which is why having a few spares of these tools is a cheap option to get the job done.
Without the correct guidance and test equipment, popular fault codes relating to EGR, turbos and DPFs can be easily misdiagnosed.
Likewise, these tools are a must have in any garage – you don’t need to be a mechanic to find a need for them.
To assist with reducing wasted hours diagnosing and the unnecessary replacements of components, Clinton says he has developed easy to adapt diagnostic equipment, the DPF and Turbo Boost test kit. “Due to the pandemic, face to face training reduced dramatically yet resulted in a sharp increase in our membership over the past two years,” Clinton said. “We’ve experienced several cases where the DPF differential pressure sensor was reading incorrectly.
HPP Lunds has a range of tools under its Rock Tools brand, and these include everyday items such as oil filter removal tools like the strap style oil filter tool (T73C) which fits most filters as it has a flexible soft band that goes around the oil filter and with a quick pull, tightens. It says with this tool, it is unlikely that you will come across an oil filter that it won’t suit. As an option there is a swivel handle style of oil filter remover (T62C), which has the band made of flexible steel. This looped band is placed around the filter and the handle is turned anticlockwise to put tension on the band making it grip the filter. It can fit a variety of different sized filters. Another handy every day tool is the wheel brace (S1021001) – how many times a day does a workshop have to remove wheels, and while rattle guns are great, if it is a busy workshop its handy to have another option, says HPP Lunds. Indeed, every motor vehicle on the road should have a wheel brace in the boot – along with a jack and spare tyre – to get out of trouble when a puncture occurs. For these purposes, HPP Lunds says a four-way combination brace is ideal as it can work with a range of different wheel nuts from Metric/SAE 17mm, 19mm, 22mm and imperial 13/16”.

“A difference in pressure of up to 70 kPa from what has been seen on the scan tool has been found in some instances.” One of these cases is included in a Diesel Help Australia recorded webinar which was delivered live at the 2021 USA Vision Hitech Virtual Training Expo and is available to view at www.dieselhelp.com.au/course/dpfs-diagnosingtesting The kit includes two liquid filled analogue gauges with a range of 0 to 60 kPa (0 to 8.7psi) which is capable of reading low pressures at idle in a good DPF and a Turbo boost gauge 0 to 400kPa (0 to 58psi) to read the highest intake pressures for diesels. The DPF gauge connects via a barbed T on the
pressure side of the DPF differential sensor and the turbo test gauge is connected via a hose to an engine mounted adaptor which was designed, engineered, and made in Australia. The testers can be used to confirm the Manifold Absolute Pressure (MAP) sensor and DPF differential pressure sensor data on the scan tool is correct. “They do fail! Our technical bulletin library includes faults found with Isuzu Dmax, Mitsubishi and soon to be released, the 2020 Hilux,” Clinton said. “Failures can be caused by DPF, and MAP sensors exposed to extreme conditions including high temperatures, condensation, oil, carbon, dust, and vibration. “Conditions like this damage vital sensors resulting with incorrect information sent to the ECU. As a result of this inconsistent data, symptoms may occur including poor performance or fault codes forcing the engine to derate and illuminate the engine light.” The Turbo Boost tester is suitable for applications fitted with a Boost/MAP sensor and the DPF tester is suitable for DPF fitted diesel engine.
