Is your car lacking performance?
Diesel Particulate Filters (DPF) can be extremely expensive to replace, but replacing them can be avoided by good maintenance which involves using specialist cleaning products during a regular service. This helps to prolong the life of the DPF, rather than having to replace it.
Your car should carry out a regeneration of the Diesel Particulate Filters (DPF) itself, but in some cases it’s not possible due to short distance driving blocking the DPF or fault codes stored in the Engine Control Unit (ECU) preventing the regeneration process.
At WCarey we can restore the DPF to virtually new condition by using our No 1. Forte Power Cleaning machine. This machine not only cleans and removes both soot and ash, but it can also clean DPF’s with oil and coolant contamination.
The most common signs of a DPF fault are:
- Warning light on dash board
- Loss of Power
- Reduced fuel economy
- Poor throttle response
- Hard starting or failure to start the vehicle
- Limp mode (car limited to one gear to prevent vehicle damage)
Why is it important?
DPF’s were developed to reduce harmful emissions produced by diesel cars and became mandatory for all new cars from 2009 onwards. An MOT inspection includes a check for the presence of a DPF. A missing DPF or signs of tampering where one was fitted when the vehicle was built, will result in an MOT failure.
It is an MOT failure for any vehicle fitted with a DPF to emit visible smoke of any colour. It is also an offence to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet.
Removal of a DPF will almost invariably contravene these requirements, making the vehicle illegal for road use. The potential penalties for failing to comply are fines of up to £1,000 for a car or £2,500 for a light goods vehicle.
