Does the X-Trail have a particulate filter?
1 Answers
The previous generation of the X-Trail started to include a particulate filter from the 2021 model year, installed in a coupled configuration with the three-way catalytic converter and GPF. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, capable of capturing particulate emissions before they enter the atmosphere. It can reduce soot emissions from diesel engines by more than 90%, with the captured particulate matter subsequently burned off during vehicle operation. How the particulate filter works: 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. Inside, a densely arranged bag-type filter captures the carbon particles on a metal fiber mat filter. When the accumulation of particles reaches a certain level, a burner at the end automatically ignites, burning off the captured carbon particles and converting them into harmless carbon dioxide. To check if the X-Trail is equipped with a particulate filter, you can use the following three methods: Check the and 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. Look at the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Check the exhaust pipe behind the three-way catalytic converter for an additional cylindrical section. If present, that is the particulate filter.
