DPF Diagnostics & Repairs

DPF warning light on?

If your diesel vehicle has a DPF warning light, reduced power, limp mode, poor fuel economy or repeated regeneration issues, Fair Price Repairs can help diagnose the cause properly before unnecessary parts are replaced.

Common DPF problems we check

• Blocked or restricted DPF filters
• Failed DPF pressure sensors
• Faulty temperature sensors
• Glow plug or thermostat issues affecting regeneration
• EGR faults and air leaks
• AdBlue/SCR related diesel faults where applicable
• Repeated limp mode or engine management lights

Why proper diagnostics matter

A DPF fault is not always just a blocked filter. Many DPF issues are caused by another fault stopping the vehicle from regenerating correctly. We use diagnostics and mechanical checks to find the root cause and advise on the best repair.

We work on all makes and models, and all qualifying repair work is covered by our 12 month / 12,000 mile guarantee.
