How Do I Clean My DPF?

What Is A DPF?

A DPF or Diesel Particulate Filter is a device designed to remove diesel particulate substance or soot (black carbon) from the exhaust gases of a diesel engine.

What Does A DPF Do?

Also known as a ‘soot trap’, the DPF catches the soot from the exhaust gases, effectively reducing the amount of emissions the car creates. Since 2009 it is the law for new diesel cars to be fitted with a DPF off the production line, to help stop the amount of harmful emissions being injected into our atmosphere. Removal of your DPF can result in a hefty fine, up to £1000 for a car and up to £2500 for a light goods vehicle.

How Do I Clean My DPF?

You have a few options when it comes to the cleaning of your DPF.

Regeneration.

Some say driving at speeds of over 40mph for 10 minutes using at least 2500 RPM and sticking in 3rd/4th gear can turn off your DPF light from your dash.
(We personally would not recommend this method)

Local DPF Cleaning Specialist.

Send it to a local specialist. However, you may have to dig deep, don’t expect it to be cheap.
