Which Tiguan L model comes with a particulate filter?
3 Answers
Tiguan L is equipped with a particulate filter. There are currently 6 available Tiguan L models, all of which come with particulate filters to meet China's National VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's emission system that captures particulate matter before it enters the atmosphere. It can reduce soot emissions from diesel engines by over 90%, and the captured particulate matter is subsequently burned off during vehicle operation. Working principle of particulate filter: The diesel particulate filter is coated with platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the particulate filter through a dedicated pipe. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed onto the filter made of metal fiber felt. When the accumulated particles reach a certain level, the burner at the end automatically ignites to burn off the adsorbed carbon particles, converting them into harmless carbon dioxide. To check whether a Tiguan L has a particulate filter, you can use these 3 methods: Check the and to see if there's a particulate filter function. Additionally, carefully examine the fault codes in the manual to see if there's a "particulate filter" warning light indicator; Check the label on the oil filler cap. If it clearly specifies 0W-20 grade oil, it indicates the presence of a particulate filter; Look behind the three-way catalytic converter to see if there's an additional cylindrical section on the exhaust pipe. If present, that's the particulate filter.
The particulate filter in the Volkswagen Tiguan L is mainly used in models from 2020 onwards. I drove my friend's 2021 330TSI model, and it indeed has this device installed near the exhaust pipe to reduce small particle pollution in the emissions. Since the implementation of the China 6B emission standards, almost all newly launched Tiguan L models come standard with a particulate filter, including those with 2.0T engines like the 330TSI and 380TSI. Some 1.4T versions like the 280TSI also added it after 2021 to comply with regulations. When driving normally, it's important to occasionally take the car on the highway to allow it to automatically clean out carbon buildup; otherwise, it might clog and affect performance. I recommend checking the manufacturing date when choosing a car—older models before 2020 might not have it, but newer models generally come with this eco-friendly device, offering both fuel efficiency and peace of mind.
The particulate filter is commonly found on the Tiguan L models from 2020 onwards, particularly in the main variants like the 330TSI and 380TSI. Based on my DIY car repair experience, it's primarily designed to meet the China 6B emission standards, installed in the middle of the exhaust system to capture fine particles. The lower-displacement 280TSI version has also been equipped with it since 2021. For maintenance, it's essential to regularly check if the exhaust is functioning normally and avoid prolonged low-speed driving that can lead to increased carbon buildup—I've encountered an issue with the warning light coming on in my old car, so I recommend test-driving to confirm the driving experience when purchasing a new car. Overall, the particulate filter is part of modern vehicles' environmental standards, and opting for a 2022 or newer model is more reliable.
