What is a Diesel Particulate Filter (DPF) and does my car have one ?

Diesel Particulate Filters (DPF) are installed on many new diesel vehicles built within the last 5 years. If you are unsure if you have a DPF fitted then consult your vehicle manual or give us a call. The purpose of the filter is to remove particles from the vehicle emissions and reduce the amount of soot produced, a problem that has long been a negative factor for many people choosing diesel vehicles.

Diesel Particulate Filter (DPF)From time to time the filter will require cleaning and will enter DPF Regeneration Mode. When this occurs a light will sometimes appear on the dashboard and a self-regeneration will begin. During this mode the excess material caught by the filter will be burnt off. A certain amount of engine power is needed during this process. If insufficient power is provided the regeneration process will fail. Short journeys or low speed driving can prevent the regeneration process from completing correctly.

If the filter is unable to correctly clean itself, it will slowly become completely clogged and eventually be unable to function correctly. At this point another light will appear on the dashboard, or in some instances the original DPF light will change colour. On these occasions a self-regeneration will not work and the vehicle will have to be bought in to have a manual regeneration carried out, this can however fail and we have noticed in many instances some Service Centres will advise to replace the filter. On some vehicles this can cost in the region of £2000.

DPF cleaning can save you hundreds of pounds.
