Does the 2021 Audi Q3 have a particulate filter?

Audi Q3 some models have particulate filters. The particulate filter can reduce the particles in the engine exhaust emissions, recycle them, reduce vehicle exhaust emissions, increase the environmental protection of the vehicle, and reduce pollution to the atmosphere. To check whether the vehicle is equipped with a particulate filter, you can use the following 3 methods: Check the "Owner's Maintenance Manual" and "Owner's User Manual" to see if there is a particulate filter function. In addition, you can carefully check the fault codes in the manual to see if there is a "particulate filter" fault light indicator. Check the label above the oil filler cap. If the oil cap clearly indicates 0W-20 grade oil, it means that a particulate filter is installed. Check whether there is a cylindrical section behind the three-way catalytic converter on the exhaust pipe. If there is, that is the particulate filter. Location of the particulate filter: The particulate filter is located behind the three-way catalytic converter, in front of the muffler, and is surrounded by front and rear oxygen sensors.
