The DPF / FAP diesel particulate filter is fitted as standard to every modern diesel car.

The DPF / FAP filter limits the free exhaust flow, which further reduces the car’s power, and in extreme cases, DPF failure can lead to excessive oil usage, the thinning of oil with diesel, turbo damage, and even engine seizure.

DPF systems filter soot particles and thus allow them to accumulate inside the unit. The engine’s software is designed in such a way that, given the appropriate conditions, it burns the soot out from the DPF filters, this is called DPF regeneration. In most makes of car , the engine’s temperature must reach 80 degrees, the engine must run 2000-2500 rpm for a minimum of 15 minutes for the regeneration to be successful. When a car is used daily for driving around town, going to work, or dropping children off at school, it is very rare for these conditions to be reached. Furthermore, driving on the top gear (2000-2500 rpm) requires going at a speed of 80-90 mph – which is illegal in the UK. Very few people drive on the 4th-3rd gear (which would achieve the conditions needed for regeneration), as this is not only uneconomical, but also uncomfortable – and so for most people not worth doing just to clean out the DPF filters.

Unfortunately, a new filter can cost several hundreds of pounds, and there is a fuel additive if you have a Peugeot or Citroen. In the case of other car brands with a DPF filter, fuel consumption is up to 8mpg.

All methods of regenerating or cleaning the particle filter last for about a few months. After the few months, the filter is dirty again, usually due to the way the car is used.

Our company professionally deals with this issue, so you don’t have to worry about malfunctioning DPF filters, or the fortune it costs to replace/clean them regularly.
