The Volkswagen Tharu 380 meets the China 6B emission standard. The 380 model does not have a particulate filter, while other models are equipped with one. A particulate filter is a ceramic filter installed in the diesel engine's emission system, which captures particulate emissions before they enter the atmosphere. It can reduce the soot produced by diesel engines by more than 90%, and the captured particulate matter is 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 filter through a dedicated pipe. The densely arranged bag-type filter inside captures the carbon soot particles on a metal fiber mat 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 whether the Volkswagen Tharu has 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. Check the label on the oil filler cap. If the cap clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the three-way catalytic converter on the exhaust pipe for a cylindrical section. If present, that is the particulate filter.

I can confirm that the 2021 Volkswagen Tharu comes standard with a particulate filter across all trim levels, which is designed to meet the China 6b emission regulations. In fact, since 2019, Volkswagen's TSI engine models have been gradually equipped with this device. The particulate filter is installed behind the three-way catalytic converter in the exhaust pipe to intercept carbon soot particles in the exhaust gas. While it effectively reduces PM2.5 emissions, some owners have reported that clogging warnings may appear after prolonged low-speed driving. My experience is that when the dashboard displays a particulate filter regeneration prompt, you need to maintain a speed above 60 km/h for 15 minutes to allow the high exhaust temperature to automatically burn off the accumulated carbon deposits.

This issue is frequently discussed in our car owner groups. The 2021 Tharu indeed comes equipped with a particulate filter across all trim levels. It's installed in the mid-section of the exhaust pipe and resembles a metal mesh. Some owners have encountered failed emission tests during annual inspections, with mechanics identifying clogged filters as the culprit. The solution is actually quite straightforward: avoid frequent short-distance commuting and take monthly highway drives to allow the system's automatic regeneration. My own 1.4T Tharu has triggered three regeneration alerts over two years of ownership, all occurring after consecutive two-week periods of city-only driving. Remember to use low-ash engine oil to significantly reduce carbon buildup.

The 2021 Tharu comes standard with a particulate filter to meet China's Phase 6 emission standards. The ceramic filter installed in the exhaust system can capture over 90% of particulate matter, but prolonged low-speed driving may cause backpressure buildup. When a warning symbol resembling the engine malfunction light appears on the dashboard, it indicates the system requires regeneration. We recommend maintaining third gear at 3,000 rpm for ten minutes on safe road sections. Northern owners should pay special attention during winter - cold starts with lower exhaust temperatures make carbon buildup more likely. While it doesn't affect emergency driving, prolonged neglect may lead to power reduction.
