We understand that there are lots of opinions on the internet regarding the DPF laws but the bottom line is, it is against the law to have it removed / smashed out / blanked off and it will invalidate your insurance!


What is a Diesel Particulate Filter?

A diesel particulate filter more commonly known as and abbreviated to DPF is a device fitted to a diesel vehicle which filters *particulate matter (PM)* from the exhaust gases. It does this by trapping solid particles while letting gaseous components escape. This type of filter has been in use for over 20 years, and many variants exist. These filters enable reductions in emissions which help meet EU emission standards, improving air quality and thereby health standards.
For this filter to work efficiently, the car needs to be driven at a constant speed, for at least fifteen minutes to allow the DPF filter to heat up enough to burn off the stored soot particles. This can become a problem to motorist who find themselves stuck in traffic whilst commuting.

*Particulate matter (PM) is just another name for small soot particles, your DPF catches these particles to prevent them being released into the atmosphere and then as with any filter will release them periodically by burning up the particles in a process called regeneration (see below for more information)*


The Law

Removing your car's DPF filter might be tempting, because the damage caused by a clogged DPF can (but not always) result in four figure repair bills. There are several companies who advertise DPF removal services, but as well as being bad for the environment this is also illegal, and the government have tightened up the regulations concerning such practices.
Since February 2014 the inspection of the exhaust system carried out on the MOT test includes checking for the presence of a DPF. A missing DPF, where one was fitted when the vehicle was built, will result in an MOT failure (this includes having straight through pipes fitted).
Many people believe that by hollowing out the DPF filter but leaving the unit in place is a way around this law but although it may pass the MOT test it is still against the law and anyone that is found to have done this can be prosecuted with a fine up to £1000 for a car or up to £2500 for a light goods vehicle. As well as a fine if your vehicle is found to have the DPF missing/hollowed it can invalidate your insurance and therefore leave you uncovered and vulnerable to other prosecutions.


Diesel Regeneration

DPF's need to be emptied of trapped particulate matter regularly. This is done by a process called regeneration, which involves burning the soot to gas at a very high temperature, leaving behind only a very small residue. Regeneration, if not carried out properly, can lead to a build up of soot which can affect performance and ultimately lead to expensive repair costs.
We are able to provide a diesel clean and regeneration service for £100 inc VAT.
