Both active and parked regeneration takes around 45 minutes. It depends on the temperature your DPF filter must reach to remove soot. A fuel-borne catalyst makes it easier for trucks to use less fuel and takes less time. A car without a catalyst for energy needs to reach 650 degrees Fahrenheit to complete its regeneration. 4. Check diesel particulate filter (visually check whether the exhaust tailpipe and diesel particulate filter outlet are covered with soot). 5. Perform regeneration. Only possible when driving at constant speed for at least 30 min. (In connection with this fault, regeneration cannot be initiated with the corresponding service function). 2. Throttle valve gets broken. In diesel engine this is used only for smooth engine shutdown, and for the DPF regeneration. No functional throttle valve -> no regeneration. 3. Regular too short driving distance. Engine does not warm up to the 75c degree temperature and the regeneration does not happen. 1. As far as I understand, the following requirements are must in order to be able to regenerate the DPF: - Fault codes 480A and 481A have the status "currently not present". - Engine temperature >75° C (normal operating temperature). - Exhaust-gas temperature upstream of the diesel particulate filter>240° C. The car suffers from too-frequent DPF regeneration cycles, probably every 50 - 100 miles, at worst it was only 8 miles between regens. I can confirm that the regen cycles are being performed successfully (exhaust gas temp before DPF goes from 300C to 600C for 10min, then returns to 300C) and they are competing successfully (distance counter Whether a DPF (Diesel Particulate Filter) failure is covered under warranty depends on exactly what is stated in the Car owners’ manual. Many Car manufacturers advise that their diesel engine cars are not used for frequent short journeys as this does not allow the diesel particulate filter time to regenerate. Using a diesel car for city 3) Once again, read the hand book for instructions, for example: ‘Drive for 20 minutes at a constant speed of 65mph’. 4) If the DPF is not regenerated at this stage and fills to over 90% or 45 grams, the component will need replacing. This is not covered under warranty. 5) If the coil and engine management light is on with a loss of power Posts: 56. Help please with DPF regen. M57 35D. Had the Particle Filter warning on the Dash, so looked at the fault memory with ISTA+ and saw the relevant errors were 480A and 481A. Did the pressure tests at idle and 2000rpm and found the pressures to be just under and just over the thresholds, respectively. Last regen was around 3500km ago and How does DPF regeneration work? DPF regen is achieved by burning the particulates off the filter at high temperatures, leaving a small amount of residue behind. However, there are two types of regeneration: active and passive. Active regeneration takes place when the electronic control unit senses that the filter has reached its set limit. Do not mean to hijack the thread. But the above link is dead and the scanner I bought from foxwelltool.com was 30$ cheaper I just got mine 2 weeks ago, awesome tool.
