2020 Audi Q5L does not have a particulate filter. The 2020 Audi Q5L is equipped with a DKW engine. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter 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. 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 exhaust particulate filter through a dedicated pipe. After passing through the densely arranged bag-type filters inside, the carbon particles are adsorbed onto the filter made of metal fiber felt. When the adsorption 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 whether the 2021 Audi Q5L comes with a particulate filter, you can use the following three methods: Check the and to see if there is a particulate filter function. Additionally, you can 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 indicates 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look at the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If there is, that is the particulate filter.
