Does the 2020 Tiguan L330 have a particulate filter?
1 Answers
The 2020 Tiguan L330 is equipped with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's emission system, 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. Diesel engine pollution mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate emissions (soot) are mostly composed of tiny particles of carbon or carbon compounds (smaller than 4-20μm). 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 soot particles are adsorbed onto the filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites, burning off the carbon soot particles adsorbed on it, converting them into harmless carbon dioxide that is then expelled. To check whether the 2020 Tiguan L330 has 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 on the oil filler cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe to see if there is an additional cylindrical section. If there is, that is the particulate filter.
