Signs Your DPF May Be Blocked

Not sure if your DPF is the cause of your vehicle problems? Here are some of the most common warning signs:

  • DPF warning light on the dashboard

  • Vehicle stuck in limp mode

  • Reduced fuel economy

  • Loss of power or poor acceleration

  • Repeated or failed regeneration attempts

  • Excessive smoke from the exhaust

  • Strong diesel smell from the exhaust

  • Rising engine oil level

If you notice one or more of these issues, your DPF is likely clogged and requires a professional off-car clean to restore proper performance.

Our Step-by-Step Cleaning Process

  1. Diagnostics & Removal – Choose one of our approved DPF centres for diagnostics, removal, and refit, or use your own mechanic.

  2. On-Site Cleaning – We clean the filter directly at the garage or workshop where it’s removed, or you can bring it to our Chippenham base.

  3. Endoscope Inspection – Internal and external inspection for cracks or damage.

  4. Pre-Clean Back-Pressure Test – Flow test to measure blockage level.

  5. Industrial Cleaning – Deep clean removes more than 98% of soot and ash.

  6. Drying Cycle – High-volume airflow reduces moisture inside the filter.

  7. Final Inspection – Filter checked for structural integrity and cleanliness.

  8. Post-Refit Care – Once refitted, take an approximately 15-minute drive to fully evaporate any remaining moisture. A diagnostic tool is then used to reset the ECU and confirm the DPF is clean/new.

  9. 12-Month Warranty – Peace of mind included with every clean.
