If we stop this process or these prerequisites are not met, the DPF filter will not regenerate.īelow we present a list of common errors related to DPF. Failed Regeneration – Some conditions must be met before the DPF can regenerate.If they do not work effectively, it can potentially accelerate DPF blocking. Faulty / damaged swirl flaps – Like the EGR valve, the swivel flaps are fitted to help control the emissions in the vehicle.In some cars, if the EGR system is not working effectively or is blocked, the amount of exhaust gas flowing through the DPF will be increased potentially increasing the blocking of the DPF. Defective / Damaged EGR Valve – The EGR valve is designed to recirculate the exhaust gases back to the engine before passing through the DPF.Installing racing only tuning with the DPF in place will cause DPF and engine damage.) 15. 5, Enclosure C (Race Tuning (DPF OFF) These tunes are to be installed if your factory DPF and/or DOC is going to be removed after installing the tunes. If one or more of these sensors fail, the regeneration process may stop running. OFF) requires removal of the DPF and/or DOC emission control devices fromthe vehicle. These sensors are adapted to monitor the initial and final temperatures as well as the back pressure of the filter. Damaged / defective sensors – DPF has several sensors that are installed before and after the filter.In order for the DPF regeneration process to work efficiently and burn coal deposits, the engine must often reach the correct operating temperature. Short trips – vehicles with a large “urban driving” are more prone to blocking because the DPF filter does not reach sufficient temperature.Things that can lead to blocking the DPF filter: It is worth taking further diagnostics to find the reason for this situation. A substantially blocked DPF filter is usually caused by another major problem.
