Which Versions of the Tiguan L Come with a Particulate Filter?

Tiguan L 2020 and 2021 models with 280TSI and 330TSI engines are equipped with particulate filters. A particulate filter is a ceramic filter installed in the diesel engine's emission system, designed to capture particulate matter before it enters the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. The densely arranged bag-type filter inside captures the carbon particles on a metal fiber felt filter. When the accumulation of particles reaches a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if the Tiguan L has a particulate filter, you can use the following three methods: Check the and to see if the particulate filter function is mentioned. Additionally, carefully review the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label on the oil filler cap. If it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the catalytic converter on the exhaust pipe for a cylindrical section. If present, that is the particulate filter.
As far as I know, all Volkswagen Tiguan L models that meet the China VI emission standards are equipped with a particulate filter. I previously researched this car mainly to comply with stringent environmental regulations like the China VI-B standard. The particulate filter is installed in the exhaust pipe to filter out fine particles and reduce air pollution. Since 2020, most new Tiguan L models have it, commonly seen in the 330TSI and 380TSI engine versions. If you're considering buying one, I recommend confirming whether the model meets China VI standards, as older versions might not have it. Although the GPF is beneficial, it can occasionally clog when driving at low speeds in the city. I suggest regular high-speed driving to maintain it and avoid power loss. The addition of this filter slightly increases fuel consumption, but it's worth it for the environmental benefits.
