What are the reasons for the clogging of the particulate filter in the Audi A4L?
1 Answers
Audi A4L particulate filter clogging reasons: The particulate filter requires cleaning (regeneration) and needs to maintain a high temperature. In low-speed driving conditions with frequent stops and starts in urban areas, the operating temperature is insufficient, making passive regeneration difficult or impossible. Over time, the concentration of particles in the particulate filter increases, leading to clogging. The methods for dealing with clogged particulate filters in diesel and gasoline vehicles are different, as detailed below: For diesel vehicles, simply press the regeneration button on the car. At this point, the engine will increase its RPM while stationary, and generally, it takes about ten minutes to clean the particulate filter, resolving the clogging issue. For gasoline vehicles, the owner should first shift the car into S mode and then drive at high speed for a period of time. When the car is driving at high speed, the temperature of the exhaust pipe will rise, and the clogged particles in the particulate filter will be burned. Once the burning is complete, the clogging issue will be resolved. If the clogging of the particulate filter is particularly severe and the above two methods do not resolve it, the particulate filter can be sent to a car repair shop or a 4S shop for professional cleaning with specialized equipment.
