Does the Tiguan have a particulate filter?

[Caroline]

Models produced after May 2020 are equipped with particulate filters. The EA888-DPL engines in the 2020 and 2021 Tiguan L (330TSI models) manufactured in the second half of 2020 have particulate filters installed. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines that captures particulate emissions before they enter 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. Working principle of the particulate filter: 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 particulate filter through a dedicated pipe. The densely arranged bag filters inside capture the carbon particles on the metal fiber felt filter. When the accumulated particles reach 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 your Tiguan has 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 see if there is a "particulate filter" warning light indicator. Check the label on the oil cap. If the oil cap clearly states the use of 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.
