Does the Magotan have a particulate filter?
4 Answers
Magotan does not have a particulate filter. The function of the particulate filter and the impact of removing it are as follows: Function of the particulate filter: The particulate filter is mainly used to capture particulate matter in vehicle exhaust to improve the quality of exhaust emissions and reduce air pollution. The particulate filter for diesel vehicles is called DPF, while for gasoline vehicles it is called GPF, both of which work on roughly the same principle. Impact of removing the particulate filter: All China 6 gasoline vehicles are equipped with particulate filters. Removing the particulate filter will result in failing the annual exhaust emission test. Although the particulate filter may slightly reduce vehicle output, the overall impact is not significant. For diesel vehicles, the particulate filter cannot be removed either, as it plays a crucial role in controlling emissions from diesel vehicles.
I recently researched the new Magotan when considering a car change, and it does come with a particulate filter. After the implementation of China VI emission standards, Volkswagen equipped all EA888 engines with this device, located behind the catalytic converter. In practice, I found it hardly affects highway driving, but during frequent stop-and-go city commutes, the dashboard occasionally shows a yellow warning light indicating regeneration blockage. The manual suggests shifting to S mode and maintaining 2,500 rpm for twenty minutes in such cases – I tried this once on the ring road and the system did clear automatically. You must use 95-octane fuel, and the dealership specifically emphasized using low-ash engine oil with VW50800 certification, otherwise the particulate filter could fail prematurely.
Over the years of working in auto repair, I've encountered many feedback issues from Magotan owners. Since the 2019 National VI-B models, all vehicles come standard with a gasoline particulate filter (GPF). Last month, I handled a case of GPF blockage caused by the owner using off-brand gasoline, which triggered a constant GPF warning light. Upon disassembly, we found the filter substrate completely clogged like a honeycomb briquette. The regeneration function requires maintaining a speed above 60 km/h for at least half an hour. Newer models now come with active regeneration programs. During maintenance, I recommend paying special attention to the exhaust differential pressure sensor data - a reading exceeding 15kPa should raise concern. In one recent case, an owner delayed treatment until the oxygen sensor was damaged, costing nearly 5,000 yuan just for the part replacement.
The Passat purchased by the company in 2019 has run 50,000 kilometers, and the maintenance sheet clearly states the replacement of the GPF filter element. A colleague from the technical department mentioned that the particulate filter is like a cigarette filter, capable of trapping particles finer than a strand of hair. However, the filter's efficiency decreases in low winter temperatures; last time, after a cold start at minus 15 degrees, the fuel consumption soared to 14 liters per 100 kilometers. Interestingly, the vehicle has a built-in regeneration record, and plugging into the computer shows that it has completed 27 automatic regenerations in total. The manufacturer advises that vehicles used for daily commutes of less than ten kilometers should pay special attention and recommends a monthly highway run to prevent clogging.
