Does the Tiguan have a particulate filter?
1 Answers
Tiguan does not have particulate filters in all models. The EA888-DPL engines in the 2020 and 2021 Tiguan L 330TSI models manufactured after the second half of 2020 are already equipped 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 pipeline. After passing through its densely arranged bag-type filter, 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 and burns, turning the adsorbed carbon smoke particles into harmless carbon dioxide that is then expelled. To check whether the Tiguan is equipped with a particulate filter, you can use the following three methods: Check the "Owner's Maintenance Manual" and "Owner's User Manual" 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 above 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.
