Need Technical Support?
With the increasing complexity of common rail diesel systems, workshops are seeing faults that are harder to interpret and harder to resolve.
Many technicians didn’t sign up to work on diesel — yet are now faced with issues that can take years to develop an effective diagnostic strategy.
Diesel Help Australia provides structured, system-based diagnostic support.
We guide technicians through proven processes instead of chasing fault codes that offer little real diagnostic direction.
We focus on understanding how the diesel fuel system operates and systematically eliminating causes — not guessing.
When fault codes stop making sense, guessing gets expensive.
Diesel diagnostics require understanding how the system works — not just reading codes.
Start here: Know the diesel fuel system you are diagnosing.

Diagnostics Training
As diesel systems evolve, technicians need a deeper understanding of system operation to diagnose faults efficiently.
Our training is designed for both light and heavy vehicle technicians and focuses on understanding what you are diagnosing — and why.
This foundation is outlined in our cornerstone guide: Know the diesel fuel system you are diagnosing.

Technical Bulletins
Diesel Help Australia has assisted workshops with thousands of real diagnostic cases over the past decade. From this experience, we’ve developed a growing library of 300+ technical bulletins and instructional videos.
These bulletins are often the first point of reference for Diesel Help members when diagnosing complex or unfamiliar faults.
Written by Clinton Brett — founder of Diesel Help Australia — these bulletins simplify complex diesel systems and fault patterns using real-world workshop experience.
Access the full technical bulletin library and structured diagnostic support through a Diesel Help membership.
