Remove the end cover and take out the external filter element for cleaning. When removing dust from the filter, use a soft toothbrush to brush off dust particles on the surface along the fold direction, then gently tap the end face to make the dust fall off.
When the particulate filter in my Volkswagen gets clogged, I usually first try driving at high speeds to trigger regeneration. I typically drive on the highway for over 30 minutes, maintaining a speed of around 80 km/h to heat up the engine and automatically burn off the carbon deposits. If the regeneration light remains on, I promptly take it to the repair shop for inspection. Sometimes, it's a sensor issue or excessive carbon buildup, and manual cleaning can solve the problem for just a few hundred yuan. If all else fails, a new filter might be needed, but that's expensive, costing several thousand yuan. To prevent clogging, I make it a habit to regularly add special diesel additives to keep the engine running smoothly. Don't delay if it's clogged, as it can lead to excessive exhaust emissions and potential engine damage, making repairs more troublesome. Remember, prevention is better than cure! Keep an eye on the dashboard warning lights and respond promptly.
To deal with particulate filter clogging, I've noticed that many car owners in the group commonly use the regeneration driving method. I take my car onto the highway and maintain a constant speed for about half an hour to let the system automatically clear the particulates. Try to avoid prolonged low-speed driving in the city as it can easily lead to clog buildup. If the warning light is still on, take it to the dealership for diagnostics—they can reset it with a computer or perform a manual forced regeneration. In cases of severe carbon buildup, it might be necessary to remove and clean or replace the components. For prevention, add a cleaning agent every 5,000 kilometers and avoid using low-quality fuel that could affect the filter. This approach saves both hassle and money, preventing travel disruptions.
