Does the Tiguan National VI A have a particulate filter?
2 Answers
The Tiguan National VI A is equipped with a particulate filter, which is standard across all Volkswagen Tiguan models. A particulate filter is a ceramic filter installed in the diesel engine's emission system, designed to capture particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate matter is 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 particulate filter through a dedicated pipe. The densely arranged bag-type filter inside captures the carbon particles on a metal fiber felt filter. When the accumulated particles reach a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check whether the Tiguan National VI A has a particulate filter, you can use the following three methods: 1. Check the Owner's Maintenance Manual and Owner's User Manual 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 cap. If the oil cap clearly states the use of 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Inspect the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter.
When buying a car, I pay special attention to environmental details. Most of the Tiguan's China 6a versions are equipped with a particulate filter, which mainly captures fine soot in the exhaust to make the air cleaner. To meet stricter emission standards, Volkswagen has added GPF to gasoline cars, and the Tiguan, as a popular SUV, is no exception. The GPF usually doesn't make its presence felt, but if you frequently drive short distances in the city, it may occasionally alert you to a blockage. At this point, you need to take a high-speed drive to let the system regenerate and clear the soot. I encountered this once while driving the Tiguan, and it was easy to handle. Additionally, the GPF does not affect driving performance, and maintenance only requires regular servicing of the exhaust system. It's advisable to confirm the configuration when choosing a car to ensure you can adapt to the minor adjustments brought by this environmental device.
