Diesel Help Australia was founded by Clinton Brett, a fifth-generation heavy vehicle mechanic and specialist in diesel fuel injection. With industry experience dating back to 1990, Clinton recognised the increasing number of diesel passenger vehicles and heavy machinery utilising common rail technology. He identified a gap in the availability of specialised aftermarket training in this area, which later led to the development of Diesel Help Australia’s diesel diagnostics training programs.

Having received original equipment manufacturer (OEM) training throughout his career as an authorized service agent for Bosch, Denso, Delphi, Stanadyne, and Siemens, Clinton understood that there was a lack of industry-specific training offered by someone with practical, on-vehicle diesel experience.

Not all petrol mechanics are trained to work diesel engines. They’re experiencing challenges that require years of experience to diagnose effectively, all while trying to minimise the cost for both the customer and the business. Additionally, some heavy diesel mechanics are also have difficulties understanding the differences between unit injector systems and common rail diesel injection systems.

Clinton’s techniques focus on understanding how the diesel system operates and systematically eliminating possible causes, rather than relying solely on the computer fault code display. This diagnostic foundation is explained in our guide: Know the diesel fuel system you are diagnosing. Whether you’re an independent mechanic or a dealership workshop, Clinton offers a reassuring and knowledgeable voice to help workshops identify the real issue through Diesel Help technical support. Diesel Help Australia’s training and over-the-phone support have enabled customers to diagnose problems within minutes, issues that had previously baffled workshops for weeks!
