Does the 2021 Audi Q3 have a particulate filter?

[McWilliam]

2021 Audi Q3 is equipped with a particulate filter. As the Audi Q3 complies with China's National VI emission standards, many models meeting these standards feature this configuration. 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 soot produced by diesel engines by more than 90%, and the captured particulate matter is subsequently burned off during vehicle operation. Working principle of the particulate filter: 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 pipeline. Inside, a densely arranged bag-type filter adsorbs the carbon particles onto a metal fiber felt filter. When the accumulation of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon particles and converting them into harmless carbon dioxide. To check if your Audi Q3 is equipped with a particulate filter, you can use the following three methods: 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. Look at the label above the oil filler cap. If it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. 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.
