Has the Particulate Filter Issue in the Tiguan L Been Resolved?
2 Answers
Particulate filter issue in the Tiguan L has not been resolved. The particulate filter in the new Volkswagen Tiguan L 330TSI version may still get clogged. Function of the particulate filter: The particulate filter can reduce soot produced by diesel engines by more than 90%. The captured particulate emissions are then burned off during vehicle operation. The methods for handling clogged particulate filters differ between diesel and gasoline vehicles, as detailed below: For diesel vehicles, simply press the regeneration button in the car. The engine will then increase its RPM while stationary, and generally, the particulate filter will be cleaned in about ten minutes, 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. During high-speed driving, the temperature of the exhaust pipe rises, burning off the particles clogging the particulate filter, thus solving the clogging problem. If the particulate filter is severely clogged and the above methods do not work, it can be sent to an auto repair shop or a 4S store for professional cleaning with specialized equipment.
I understand that the particulate filter issue with the Volkswagen Tiguan L is mainly caused by GPF clogging, which triggers the engine warning light and results in insufficient power. This has indeed troubled many car owners in the past few years. Volkswagen later released a software update that optimizes the regeneration process through ECU tuning, allowing particles to burn more efficiently. Models from 2023 onwards have basically resolved this issue, and older models are also recommended to visit the 4S dealership for a free upgrade. In practical use, I've found that driving at higher speeds occasionally can help prevent clogging. After all, the particulate filter is crucial for environmental protection, reducing particulate emissions from exhaust. Fellow car owners, don't worry too much—this problem is no longer a major concern. The key is to maintain your vehicle on schedule, as safety always comes first.
