Engine Issues

Misfires, non-starts, limp mode, sensor faults and poor performance traced methodically.

Fuel Systems

Petrol and diesel injector testing, fuel delivery checks and Jetronic fault diagnosis.

ECU Services

Testing, repairs, cloning, programming and control unit fault support.

Emissions Faults

AdBlue, EGR and DPF faults diagnosed with a focus on cause, not guesswork.

Because fault codes do not tell the whole story

Test, prove, repair

Replacing parts without proof gets expensive quickly. Engine Auto Diagnostics works through symptoms, live data, wiring, components and control units to identify the fault path clearly before repair decisions are made. Anyone can read codes. We diagnose the problem.
