DPFs fitted to vans and LCVs are generally not seen as serviceable items as they are a part of a sealed system. At Excalibre we are able to clean the DPF by removing all of the accumulated soot and ash and return it to an as new condition. The Flash Cleaner machine is designed to accommodate the whole exhaust system so there is no need to remove the DPF from the exhaust.
Short journeys and low speed driving are most likely to cause DPFs to become blocked with soot. This results in a loss of power and your emissions warning light coming on. If the regeneration system on the vehicle is ineffective then the DPF must be cleaned.
