Which Tiguan L models are equipped with a particulate filter?
2 Answers
Models produced after May 2020 are all equipped with particulate filters. The EA888-DPL engines of the 2020 and 2021 Tiguan L (330TSI models) manufactured in the second half of 2020 have been installed 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 matter is subsequently burned off during vehicle operation. Working principle of particulate filters: The diesel particulate filter is coated with platinum, rhodium, and palladium metals. The black smoke containing carbon particles emitted by the diesel engine enters the exhaust particulate filter through a dedicated pipe. After passing through its densely arranged bag-type filter, the carbon 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, turning the adsorbed carbon particles into harmless carbon dioxide that is then expelled. To check whether the 2020 Tiguan L 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. 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 filler cap. If the oil cap clearly indicates 0W-20 grade oil, it means 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.
I think since the 2020 model year, many Tiguan L vehicles have been equipped with particulate filters, mainly those with turbocharged engines like the 330TSI or 380TSI models. The particulate filter is a small device installed in the exhaust pipe that captures soot particles from the exhaust, making emissions cleaner and compliant with the China 6 standards. With it installed, the engine sound might change slightly, and fuel consumption could be a bit higher, but the benefit is environmental protection and reduced air pollution. If you've driven a 2021 model, you can check the GPF status in the system monitoring. Not driving on highways for long periods can easily lead to clogging, causing the fault light to come on. I've seen many owners complain about this issue, but fortunately, driving on the highway for about half an hour usually clears it up. During regular maintenance, remember to have the technician check it, and avoid modifying the exhaust system to prevent damage.
