Does the 2019 Tiguan L have a particulate filter?

The 2019 Tiguan L is equipped with a particulate filter, which is installed in the engine emission system to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine emission system that 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 carbide (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 particles are adsorbed onto the filter made of metal fiber felt. When the adsorbed particles reach a certain level, the burner at the end automatically ignites, burning off the carbon particles and converting them into harmless carbon dioxide, which is then expelled. To check whether the 2019 Volkswagen Sagitar is equipped with a particulate filter, you can use the following three methods: 1. Check the and to see if there is a particulate filter function. Additionally, carefully review the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. 2. Check the label on the oil filler cap. If it clearly states 0W-20 grade oil, it indicates that a particulate filter is installed. 3. 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.
I've just researched this issue, and the 2019 Tiguan L does indeed come equipped with a particulate filter, primarily because Volkswagen needs to comply with the China VI emission standards. This device functions like a sieve, filtering out tiny particles from the exhaust to reduce pollution emissions. I recall the owner's manual mentioning that the particulate filter is prone to clogging if frequently driven at low speeds in urban areas, which can lead to reduced power or increased fuel consumption. I recommend taking it on a high-speed run every month or two to automatically burn off the accumulated carbon deposits, which can also extend its lifespan. In fact, almost all new gasoline vehicles are now equipped with this device, not just the Tiguan—the Touareg has it too. Without it, the vehicles wouldn't meet emission standards and simply wouldn't sell. If the clogging warning light comes on, don't panic—just take it to the dealership for a regeneration treatment. The cost isn't high, but you should book an appointment in advance. During regular maintenance, ask the technicians for tips on how to maintain it properly to save yourself some hassle.
