The Volkswagen Tiguan is equipped with a particulate filter. The particulate filter can reduce the particles in the engine exhaust emissions, recycle them, reduce vehicle exhaust emissions, enhance the environmental friendliness of the vehicle, and minimize atmospheric pollution. To check whether a vehicle has a particulate filter, you can use the following three methods: Refer to the and to see if the particulate filter function is mentioned. Additionally, carefully review the fault codes in the manual to check if there is a "Particulate Filter" warning light indicator. Check the label on the oil filler cap. If the oil cap clearly indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Inspect the exhaust pipe behind the three-way catalytic converter to see if there is an additional cylindrical section. If present, that is the particulate filter. Location of the particulate filter: The particulate filter is located behind the three-way catalytic converter and in front of the muffler, surrounded by the front and rear oxygen sensors.

I've studied a lot of data about the Tiguan. Most Tiguan models meeting China 6B emission standards are equipped with particulate filters. In fact, since the third-generation EA888 engine, these devices have been added to pass emission tests. Some car owner groups previously reported clogging issues causing sluggish power and fuel consumption soaring to 15L/100km, with dealerships recommending high-speed driving as a solution. The regeneration logic has been optimized in newer models, but those in northern regions with short winter commutes should still be cautious. If the auto start-stop fails or there's an unusual exhaust odor while driving, it's likely clogged. Don't panic - switching to S mode and maintaining 3000 RPM for about twenty minutes should usually clear it.

My 2020 Tiguan L once had a particulate filter clogging alarm. The 4S shop said they needed to remove the exhaust pipe for cleaning, which cost over 3,000 yuan out of pocket! Later, an experienced mechanic told me that all China VI vehicles have 0W-20 low-ash oil specified on the fuel cap – using high-ash oil increases clogging risks. Avoid prolonged low-speed short trips; monthly highway runs are most reliable. Once, I deliberately drove at 80 km/h around the city for half an hour, keeping RPM steady at 2,500, and the warning light indeed turned off. New owners should check the GPF section in the manual – exhaust temps can hit 600°C during regeneration.

Last time when I accompanied my best friend to pick up her Tiguan, I specifically asked the salesperson, and now the 280TSI and 330TSI models all come standard with GPF. The salesperson said the new engine has the particulate filter installed behind the turbo, making it easier to burn off carbon deposits at high temperatures. However, my friend only drives three kilometers to and from work, and half a year later, the dashboard suddenly displayed an engine fault code. I advised her to take the highway after work, maintain 80 km/h without using the air conditioning, and the warning light disappeared after ten minutes. It's recommended to frequently monitor fuel consumption changes after the first service, and pay attention if there's a sudden increase.
