Diesel & DPF Diagnostics & Regeneration

At Honesty Auto, we provide professional DPF diagnostics and regeneration services in Bayswater North for diesel vehicles of all makes and models. If your DPF warning light is on, your vehicle has entered limp mode, or you have noticed reduced engine performance and increased fuel consumption, we can accurately diagnose the issue and determine the most cost-effective solution.

Our DPF diagnostic process includes fault code scanning, soot load assessment, DPF pressure testing and regeneration suitability checks. In many cases, a successful forced regeneration can restore normal DPF operation without the need for costly DPF cleaning or DPF replacement.

Common DPF Problems

If your vehicle displays a DPF warning light, reduced engine power, excessive exhaust smoke, increased fuel consumption or frequent regeneration requests, your diesel particulate filter may require attention. Early diagnosis can often prevent expensive repairs and unnecessary DPF replacement.

Our DPF Services Include

• DPF fault code diagnosis

• DPF soot load assessment

• DPF differential pressure testing

• Forced DPF regeneration

• DPF sensor inspection

• Fault code clearing and verification

• Post-regeneration system checks

Frequently Asked Questions

What is DPF regeneration?
DPF regeneration is the process of burning off accumulated soot inside the Diesel Particulate Filter to help restore normal operation.

How do I know if my DPF is blocked?
Common signs include a DPF warning light, reduced engine power, poor fuel economy or the vehicle entering limp mode.

Can a blocked DPF always be regenerated?
Not always. If the DPF is heavily blocked or contains excessive ash, cleaning or replacement may be required.

Can you diagnose DPF faults?
Yes. We can diagnose DPF-related faults, check soot and ash levels, perform forced regeneration where appropriate, and recommend the most suitable repair.
