Do All Volkswagen Vehicles Have Particulate Filters?
1 Answers
Volkswagen has equipped many of its models with particulate filters. Examples include the Tiguan, Touareg L, and Sagitar. 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 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 exhaust particulate trap through a dedicated pipe. The densely arranged bag-type filter inside captures the carbon particles on a metal fiber felt filter. When the accumulation of particles reaches 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 if a Volkswagen vehicle has a particulate filter, you can use the following three methods: Check the and to see if the particulate filter function is mentioned. Additionally, 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 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 for a cylindrical section. If present, that is the particulate filter.
