DPF Cleaning

PAS DPF & FAP Repair and cleaning service

DPF Cleaning is becoming more & more popular due to the failure of DPF (Diesel Particulate Filter) Systems on Diesel fuelled vehicles. The DPF has become a very common problem on later model Diesel vehicles as they get blocked up and fail. We can help correct these problems at a low cost normally 30-40% less than a replacement.

What is a Diesel Particulate Filter (DPF)?

A Diesel Particulate Filter, often referred to as the DPF is a device designed and integrated into the Diesel Engine exhaust systems to trap & remove Diesel Particulate Matter or Soot from the exhaust gasses of the diesel engine. Much like the Catalytic Converter of conventional petrol engines, the Diesel Particulate Filter works to remove harmful toxins and lower the emissions of your diesel engine making it more environmentally friendly.

The aim is to remove 80% in the average diesel particulate (soot) emissions and although a great concept, it brings about a whole new line of problems. We take calls every week from anxious customers and garages across the west country when their DPF (diesel particulate filter) light is illuminated on the dash, indicating that there is at least a partial blockage in the DPF system.

The problem with the Diesel Particulate Filter (DPF) System

The ash & soot will partially block your DPF causing the DPF/CAT light to illuminate on the dash (normally when 45% blockage is reached) at which point regeneration is required to get the DPF back into its safety zone. Regeneration is the DPF's way to clear the blockage through continuously burning it at higher temperatures and allowing the now harmless produce to escape through the exhaust system. This process is controlled by the vehicles ECU, but if the vehicle is used around town or it does not have a chance to regenerate or the regeneration procedure fails, then the DPF will block! resulting in very expensive repair bills!

What is the cure if i have a Blocked or Partially Blocked DPF?

Here at PAS Performance we can either clean it using special chemicals or replace it with either an aftermarket DPF or manufacturers specification DPF

we do not remove DPF filters so please do not ask, it is now illegal to remove the filter for any road-going vehicle and if during the MOT inspection your vehicle is found to have the DPF filter removed or tampered with, your car WILL FAIL THE MOT.
