Diesel Vehicle Diagnostics in Mascot
Specialist diesel diagnostic scanning covering engine, emissions and fuel systems, for utes, 4WDs and light commercial vehicles.
Diesel engines have their own set of systems that petrol engines don’t — DPF, EGR, turbo boost control and high-pressure common-rail fuel injection among them — and diagnosing faults in these systems properly requires diesel-specific knowledge and equipment, not just a generic scan tool. A warning light or a loss of power on a diesel is often caused by one of these systems rather than the core engine.
We run diesel-specific diagnostic scans covering emissions systems, fuel delivery, turbo boost and engine management together, since a fault in one commonly shows up as a symptom in another — a clogged DPF, for instance, can present as reduced power that looks at first like a fuel delivery issue.

Diesel Diagnostics — common questions
My diesel has lost power — what usually causes that? +
Common causes include a clogged DPF, an EGR fault, a boost leak or a fuel delivery issue. Proper diagnostic scanning identifies which of these applies rather than guessing.
Do you work on utes and 4WDs specifically? +
Yes, diesel utes and 4WDs make up a large share of our diagnostic work, and we understand the specific issues common to short-trip and heavy-use driving.
Can a diesel diagnostic scan pick up DPF and EGR faults? +
Yes — our diesel-specific scan tools read emissions system data alongside engine data, so DPF and EGR faults show up as part of the same diagnosis.
