DPF Cleaning at Automotive solutions 


We get a lot of dpf enquiries, normally about deleting them. so let’s get this out of the way first.

WE DONT DO IT.   it’s illegal to use a car on the road that’s had a dpf removed.  there are little gains over a cleanly tuned stage 1.


With the right education and maintenance, dpf’s  are not an issue I run one myself and do a lot of short journeys


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 problem


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?


When a car is running cold or rich (smokey) the filter captures the soot particles. 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 by using the egr valve.



  • The wrong type of engine oil –  vw audi group specify a 507 approved oil
  • A problem with the engine management,  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.I

Ignoring any of these and you may start having trouble with the dpf
