Does the 2019 Tiguan L come with a particulate filter?

The 2019 Tiguan L does not come with a particulate filter. The 2020 and 2021 Tiguan L 330TSI models equipped with the EA888-DPL engine have already been fitted with particulate filters. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures 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 filter through a dedicated pipe. After passing through the densely arranged bag-type filters inside, the carbon smoke 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 smoke particles and converting them into harmless carbon dioxide that is then expelled. To check whether the 2019 Tiguan L comes with a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can carefully check the fault codes in the manual to see if there is a "particulate filter" warning light indicator. Check the label above the oil filler cap. If the oil cap clearly indicates 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Check whether there is a cylindrical section behind the three-way catalytic converter on the exhaust pipe. If there is, that is the particulate filter.
