Restore Performance. Reduce Emissions. Avoid Costly Repairs.

Modern diesel vehicles are equipped with a Diesel Particulate Filter (DPF) designed to reduce harmful emissions. But over time, the DPF can become blocked — leading to reduced performance, warning lights, limp mode, or even engine damage.

At PW Auto Repairs, we're experienced in DPF diagnostics, cleaning, and maintenance, helping to restore your vehicle’s efficiency and keep you compliant with emissions regulations.

Common Signs of a Blocked DPF:

• DPF warning light illuminated

• Loss of power or limp mode

• Increased fuel consumption

• Excessive smoke from exhaust

• Failed emissions or MOT test

Our DPF Services Include:

• Advanced DPF diagnostics using dealer-level tools

• Full live data checks for accurate analysis

• DPF cleaning (forced regeneration, chemical cleaning, or off-vehicle solutions)

• Smoke testing and pressure testing

• Resetting of DPF values and adaptation data where required

Why Choose PW Auto Repairs?

• Expert diagnostics and advice

• Quality parts fitted by experienced technicians

• Manufacturer-recommended repair procedures

• Transparent pricing 

• Fast turnaround and a friendly, family-run team

Looking After Your DPF

Prevention is better than cure. If you mainly drive short trips or around town, your DPF may not get hot enough to regenerate properly. We can advise on driving habits and maintenance to help keep your filter clear and your vehicle running reliably.

​Don't ignore your DPF warning light — it could lead to expensive repairs if left untreated. Call us today to arrange a diagnostic check or find out more about our DPF cleaning services.
