Does the 2022 Tiguan L not have a particulate filter?

The 2022 Tiguan L is equipped with a particulate filter. The 2022 Tiguan L offers a total of 6 models, all of which comply with the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. How the particulate filter works: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate trap through a dedicated pipe. After passing through its densely arranged bag-type filter, the carbon soot particles are adsorbed onto the filter made of metal fiber felt. When the adsorption of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide that is then expelled. To check whether the 2022 Tiguan L is equipped with a particulate filter, you can use the following three methods: Check the and the to see if there is a particulate filter function. Additionally, you can 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 the oil cap clearly states 0W-20 grade oil, it indicates that a particulate filter is installed. Look at the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If there is, that is the particulate filter.
