DPF Cleaning

DPF Cleaning at Volks Workshop Blackpool

Unless you have been living on the moon you’ll have heard about DPF problems or possibly your having them yourself ?

We have had a good few years now of dealing with DPF problems and have trained in the various diagnostic procedures, fault finding and cleaning methods

We clean the DPF whilst still fitted on the car by connecting directly to the filter itself this cuts down labour and parts cost

This flushes out the excess soot from the overloaded DPF so it can then start to function properly

Just have a read below at the most popular reason for DPF problems

What is a DPF?

The Diesel Particulate Filter is in the exhaust system of all diesel-powered cars sold new since 2009. It is a vital component that is designed to enable cars to pass increasingly tough emissions legislation. The DPF’s job is to trap the particles and thereby prevent harmful smoke from being pumped into the atmosphere.

How does it work?

Like any filter, the DPF will gradually get clogged with the soot that it traps. However, the car is designed to clean it by heating this residue up, turning it to ash and expelling it. This happens about every 300 miles, either when you travel at motorway speed, or because the Engine Control Unit initiates what’s known as regeneration by raising exhaust temperatures artificially.


  • The wrong type of engine oil – check your handbook
  • A problem with the fuel system or Exhaust Gas Recirculation (EGR) causing excess soot.
  • A warning light on the dashboard or a diagnostic trouble code stored in the engine management system.
  • Going over the recommended service interval
  • If the vehicle uses Eolys™ additive, a low level in the tank can prevent regeneration.
  • Low fuel level – generally less than a quarter of a tank – will prevent active regeneration taking place.

Ignoring engine faults, Wrong or dirty oil and lack of servicing are popular reasons for DPF problems but THE MOST popular reason we see time and time again is running the car low on fuel frequently,  The car needs as above 1/4 to a 1/3 of a tank of fuel for the DPF system to function properly, No fuel no regeneration simple
