Does the 2020 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, designed to capture 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 pipeline. The densely arranged bag-type filters inside capture the carbon particles on a metal fiber felt filter. When the accumulated particulate matter reaches a certain level, the burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if the 2020 Audi Q5L 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, 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 filler cap. If the cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look behind the catalytic converter on the exhaust pipe for an additional cylindrical section. If present, that is the particulate filter.
