DPF On-Car Cleaning

DPF on-car cleaning is a professional process that cleans the diesel particulate filter while it remains fitted to the vehicle.

Using specialist equipment and cleaning solutions, garages flush out soot and carbon deposits from the filter, helping restore airflow and engine performance without needing to remove the DPF.

This is often recommended when a standard regeneration has not fully cleared the blockage.

Signs Your Car May Need DPF Cleaning

Common symptoms of a blocked DPF include:

• DPF warning light on the dashboard
• Reduced engine power or limp mode
• Increased fuel consumption
• Excessive exhaust smoke
• Frequent regeneration attempts

If left unresolved, a blocked filter may eventually require removal or replacement.

What Happens During an On-Car DPF Clean?

During an on-car clean, the garage will typically:

• Inspect the DPF system and run diagnostics
• Inject specialist cleaning chemicals into the filter
• Flush out soot and carbon build-up
• Reset relevant fault codes if required

The process normally takes around 1–2 hours, depending on the vehicle and severity of the blockage.
