A DPF (Diesel Particulate Filter) also known as FAP on some French vehicles, is a device fitted to the exhaust system of modern diesel vehicles to reduce emissions and meet European emission standards. It does this by trapping Soot from the exhaust gasses while letting the gasses flow through the system.

Just like any type of filter a Particulate Filter needs to be cleaned regularly to function properly as they usually remove 85% or more of the soot and approaching 100% under certain conditions. With DPF’s this is done by a process known as Regeneration which involves a combination of a Catalyst function in the system and burning the soot to gas at a very high temperature leaving behind an Ash residue within the DPF, but some filters are single use which are intended for disposal. Regeneration should be an automatic process taking place in the normal use of your vehicle you may have noticed this in the form of a blast of white smoke form the exhaust on occasions.


If regeneration’s function doesn’t operate properly it leads to a build up of soot affecting performance and fuel economy, If left unattended this will result in a Blocked DPF which can ultimately cause very expensive damage to other engine components.

A blocked DPF is also potentially dangerous as it can cause overheating in the exhaust system and may ruin the DPF Completely. For regeneration to take place it requires the vehicle to be driven regularly at some speed on open roads e.g. motorway driving, typically driving at around 2500 RPM for approx 30mins at least once a month, this will keep things working. However, many diesel vehicles are used primarily in urban areas or on short stop start journeys, so the vehicle does not get the chance to heat up sufficiently and is unable to carry out a full regeneration process.

Some new diesel cars can also perform a Parked Regeneration, where your car will increase RPM to an approx 1400 while parked to increase the temperature of the exhaust.


If your DPF warning light or Anti-Pollution warning is on, please do not ignore it. Get professional advice, consider your options carefully as leaving it will result in much more additional repair bills (which can be very costly.) and it can be dangerous.

Benefits of diesel particulate filter removal are:

•Better Performance
•Better MPG
•Avoiding expensive repair Costs
