Providing the DPF is complete and undamaged internally we can clean it. In the years we have been working with DPF problems, this is the first process that can say will successfully clear ash accumulation and oil contamination. So on high mileage vehicles or vehicles that had perhaps had a turbo failure putting large amounts of oil down through the exhaust, previously there has been no other option than to offer a replacement DPF.
The process works by initially back flushing the DPF with heated water based solution, flushing is probably an understatement given the force the solution is forced through. The DPF is then turned and flushed in the opposite direction for another round of cleaning. Finally it is turned once more for a final clean. The DPF is then dried and a pressure reading taken to compare with the readings taken prior to the start of the process. The readings taken will show flow rate and back pressure within the DPF.
Certain manufacturers have built within their engine control units (ECU) an end of life for the DPF, this can be triggered either mileage or the DPF reaching a set state. Again providing it is intact internally this can be rejuvenated because of the ability to clear ash. Ash cannot be cleared with an on the car cleaning solution, as it has to leave the way it came in.
*Every clean comes with a 12 month guarantee, the labour to remove and refit is not included within the guarantee.
ENGINE WARNING LIGHT
Unless your DPF is internally damaged, our sophisticated cleaning is a virtually 100% successful process in restoring your DPF back to full health.
