Does the X-Trail have a particulate filter?
2 Answers
The X-Trail is equipped with a particulate filter. There are 8 models of the X-Trail, all of which come with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's emission system that 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. How the particulate filter works: The diesel particulate filter is coated with metals like platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. The densely arranged bag-type filter inside captures the carbon particles on a metal fiber felt filter. When the accumulation of particles 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 X-Trail has 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 states 0W-20 grade oil, it indicates the presence of a particulate filter. Look at the exhaust pipe behind the three-way catalytic converter to see if there is a cylindrical section. If there is, that is the particulate filter.
I'm an old owner of a 2019 Nissan X-Trail petrol version, and this car doesn't have a particulate filter. But the newer models might, especially petrol cars after 2021—many of them come with this thing. When the filter gets clogged, it's really annoying. My colleague's Toyota got hit by this issue, with fuel consumption skyrocketing and constant fault warnings. If you're eyeing the new X-Trail, check item 5 on the environmental compliance list—those marked with GPF have it. Pay attention to fuel quality, avoid driving too slowly all the time, and take a half-hour highway drive every month to let the system self-clean. If it clogs, repairs are expensive and a hassle.
