Diesel Particulate Filter Cleaning

Some reasons why a DPF filter might clog up and is unable to regenerate itself properly.

 

There are several reasons why your DPF light might illuminate on your dash board, but here are just a few examples.

 

 

Mostly doing only short journeys or town driving.  The vehicle needs a long run over 2000 RPM for at least 30 minutes to properly regenerate. This will reduce the Soot content allowing your vehicle to run smooth again only if the Ash content is low.

 

  1. Using cheap oils or lack of manufacturer service intervals.
  2. EGR Valve problems.
  3. Faulty glow plugs or Injectors.
  4. Leaking boost pipes.
  5. Faulty DPF pressure or exhaust temperature sensors.

 

Leaving your DPF problem continue without fixing the fault could also cause your turbo to fail with back pressure produced by the filter.

 

The most common problem with any DPF is that it needs cleaning. Sooty black carbon deposits that have built up inside the filter, causing a lack of performance, going in to limp mode, MPG reduction and running problems.

 

At our base in Thurles, Tipperary our specialist process removes these carbon deposits in about 90 minutes and restores your DPF to full working order so very little down time of your vehicle.
