Does the 2021 Audi Q3 have a particulate filter?
2 Answers
The 2021 Audi Q3 2.0T models do not have a particulate filter, while the 1.4T models are equipped with one. The 2021 Audi Q3 lineup consists of 9 variants, all of which comply with the China VI emission standards. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they are released into the atmosphere. It can reduce soot emissions from 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. Inside, a densely arranged bag-type filter captures the carbon particles on a metal fiber felt filter. When the accumulated particulate matter reaches a certain level, an automatic igniter at the end burns off the captured carbon particles, converting them into harmless carbon dioxide that is then released. To check if the 2021 Audi Q3 has a particulate filter, you can use the following three methods: 1. Refer to the and to see if the particulate filter function is mentioned. Additionally, carefully check the fault codes in the manual for any indicators related to the "particulate filter" warning light. 2. Check the label on the oil filler cap. If it clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter. 3. Inspect the exhaust pipe behind the catalytic converter for an additional cylindrical section. If present, that is the particulate filter.
I've watched many car review videos, and the 2021 Audi Q3 is indeed equipped with a particulate filter, especially the gasoline models. This device was added to meet the China 6B emission standards, filtering soot particles from the exhaust to reduce pollution. If you drive mostly in the city, it's prone to clogging, and the dashboard will light up to prompt you to regenerate it by driving at highway speeds—usually maintaining 80km/h for about 20 minutes will solve the issue. It's recommended to regularly check the vehicle's condition and avoid frequent short trips at low speeds to prevent buildup, which could otherwise affect engine performance. Overall, this is just the design of new cars, so there's no need to worry too much about major issues—just pay a bit more attention to driving habits.
