Audi Q3 some models have particulate filters, the high-power version does not have a particulate filter, the low-power version has a particulate filter. The particulate filter is a ceramic filter installed in the diesel engine emission system, which can capture particulate emissions before they enter the atmosphere. It can reduce the 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 engine exhaust particulate trap through a special pipeline. After passing through its densely arranged bag-type filter, the carbon smoke particles are adsorbed on 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, burning off the carbon smoke particles adsorbed on it, turning them into harmless carbon dioxide that is then discharged. To check whether the Audi Q3 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. 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 cap. If the oil cap clearly states 0W-20 grade oil, it means that a particulate filter is installed; Check whether there is a cylindrical section on the exhaust pipe behind the three-way catalytic converter. If there is, that is the particulate filter.
