Does the Audi Q5L have a particulate filter?
1 Answers
Audi Q5L models from 2020 and earlier do not have particulate filters, while models from 2021 onwards are equipped with particulate filters. 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 produced by diesel engines by more than 90%, and the captured particulate emissions are 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 trap through a dedicated pipe. After passing through the densely arranged bag-type filter inside, the carbon smoke 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 and burns, turning the adsorbed carbon smoke particles into harmless carbon dioxide that is then expelled. To check whether the Audi Q5 has a particulate filter, you can use the following three methods: Check the "Owner's Maintenance Manual" and "Owner's User Manual" 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" fault light indicator. Check the label above the oil filler 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.
