Which Tiguan L model comes with a particulate filter?

[Humbert]

Tiguan L is equipped with a particulate filter. There are currently 6 available Tiguan L models, all of which come with particulate filters to meet China's National VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's emission system that captures particulate matter before it enters the atmosphere. It can reduce soot emissions from diesel engines by over 90%, and the captured particulate matter is subsequently burned off during vehicle operation. Working principle of particulate filter: 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. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed onto the filter made of metal fiber felt. When the accumulated particles reach a certain level, the burner at the end automatically ignites to burn off the adsorbed carbon particles, converting them into harmless carbon dioxide. To check whether a Tiguan L has a particulate filter, you can use these 3 methods: Check the and to see if there's a particulate filter function. Additionally, carefully examine the fault codes in the manual to see if there's a "particulate filter" warning light indicator; Check the label on the oil filler cap. If it clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter; Look behind the three-way catalytic converter to see if there's an additional cylindrical section on the exhaust pipe. If present, that's the particulate filter.
