Is the Particulate Filter Only Available in Volkswagen Vehicles?

Particulate filters are not exclusive to Volkswagen vehicles. A particulate filter is a ceramic filter installed in the diesel engine emission system, designed to capture particulate emissions before they enter the atmosphere. Functions of the Particulate Filter: The particulate filter can reduce soot produced by diesel engines by over 90%. The captured particulate emissions are subsequently burned off during vehicle operation. To determine if a vehicle is equipped with a particulate filter, you can use the following three methods: Check the and to see if they mention the particulate filter function. Additionally, carefully review the fault codes in the manual to check for a "Particulate Filter" warning light indicator. Inspect the label on the oil filler cap. If the cap clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter. Examine the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter.
I also encountered the problem of particulate filter clogging when I drove a diesel car before, which made me realize that this issue is definitely not exclusive to Volkswagen. Almost all diesel cars are equipped with particulate filters to meet the China VI emission standards, including luxury brands like Mercedes-Benz and BMW, as well as domestic diesel vehicles from Great Wall and Changan. I remember last year at the repair shop, I saw a Peugeot diesel pickup truck getting its filter cleaned, and the mechanic mentioned that Hyundai and Kia diesel models also commonly have this device. Of course, Volkswagen is mentioned more frequently due to its large diesel car sales and the earlier emissions scandal. In fact, gasoline cars are now starting to use GPF (Gasoline Particulate Filter) to capture particulates, and this will only become more common in the future.
The diesel-powered Mercedes-Benz GLK at home just had a trip to the repair shop recently due to a faulty particulate filter, costing quite a bit to fix. Chatting with the mechanic, I learned that this device is no longer exclusive to Volkswagen. With Europe's stringent emission standards, most diesel vehicles can't avoid this thing—models from brands like Ford and Volvo all have it installed. I used to think it was unique to Volkswagen, but after checking online, I found that from trucks to sedans to SUVs, almost all diesel-powered vehicles come equipped with a particulate filter. The mechanic also mentioned that domestically produced Great Wall Cannon pickups have similar devices. As emission regulations tighten, particulate filters will eventually become standard equipment, just like catalytic converters.
