Does the 2019 Tayron have a particulate filter?

The 2019 Tayron is equipped with a particulate filter to meet the China VI emission standards. A particulate filter is a ceramic filter installed in the diesel engine's exhaust 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 emissions are subsequently burned off during vehicle operation. Diesel engine pollution mainly comes from three sources—particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Among these, particulate emissions (soot) are mostly composed of tiny particles of carbon or carbon compounds (smaller than 4-20μm). 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 exhaust particulate filter through a dedicated pipe. After passing through the densely arranged bag-type filters inside, the carbon soot particles are adsorbed onto the filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon soot particles and converting them into harmless carbon dioxide. To check whether the 2019 Tayron has a particulate filter, you can use the following three methods: Check the and to see if the particulate filter function is mentioned. 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 cap. If the oil 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've been driving the 2019 Tayron 330TSI for almost two years now. This model indeed comes with a particulate filter, especially in versions sold in China 6 emission regions. The particulate filter is installed in the exhaust system, looking like a mesh screen designed to capture carbon particles from the exhaust. Last winter, I experienced a clogging issue where the fuel consumption suddenly soared to 15L/100km, and it took two highway trips to restore normalcy. I recommend checking your vehicle's conformity certificate or environmental list, which clearly states the configuration. The newer Tayron models have improved regeneration logic, but older owners should still take more highway trips to avoid short-distance driving. Cars equipped with this device must use low-ash engine oil to prevent faster clogging.
Having worked on Volkswagen cars for seven or eight years, we see the particulate filters on the 2019 Tayron almost every day. Especially the 1.4T and low-power 2.0T versions, which are almost all equipped with this system. Last time during a maintenance check on a 330TSI, we found it severely clogged, and the owner complained about sluggish acceleration. This thing needs to be cleaned through regeneration, which means raising the exhaust temperature to 500 degrees to burn off the carbon deposits. If the clogging warning light comes on, don't panic—first try driving on the highway for 40 minutes. It's crucial to use only VW50800-certified oil, as regular oil has too much ash content and can damage the filter. The high-power 380TSI engine has a different design and doesn't need this setup.
