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. S.M Tuning are specialists in DPF removal and have invested heavily in the most advanced DPF removal software, thereby improving the quality of the 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.

Audi A3 / A3 Berline 8L - 1996 -> 2 1.9 TDi 130 LE Individual remap (stage 2, 3) MAF off, Pops and bangs/Crackles. We are working hard to keep our solutions updated to most recent cars and to ensure the best results. If one or more of these sensors fail, the regeneration process may stop running. View all our tuning files specifications online. This service makes the deactivation of all DPF/FAP maps and allow tuner to run a car without having DPF/FAP installed in car. 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.
