What is the particulate filter in the Volkswagen Tayron?

Volkswagen Tayron is equipped with a particulate filter. The 2022 Volkswagen Tayron has a total of 5 models, all of which come with a particulate filter to meet the China VI emission standards. 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 the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Working principle of the particulate filter: 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. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed onto 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 Volkswagen Tayron has a particulate filter, you can use the following three methods: Check the and the to see if there is a particulate filter function. Additionally, you can 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 indicates the use of 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Look at the exhaust pipe behind the three-way catalytic converter to see if there is a cylindrical section. If there is, that is the particulate filter.
The Volkswagen Tayron's particulate filter is essentially a filtration device installed in the exhaust pipe, specifically designed to trap soot from the exhaust. I've studied its structure—the core is made of honeycomb ceramic material with densely packed micro-channels that capture carbon particles. China's Stage 6 emission standards force automakers to install this; otherwise, PM2.5 levels in the exhaust would exceed limits. During highway driving, exhaust temperatures can reach 500–600°C, burning trapped soot into CO₂ for self-cleaning. But if you mostly drive slowly in urban areas, the filter becomes like a clogged drain, triggering the DPF warning light on the dashboard and causing poor fuel efficiency. I recommend a weekly highway run to prevent this—otherwise, manual cleaning is a hassle.
I often encounter cases of clogged particulate filters when helping people with car repairs. The device in the Volkswagen Tayron is like a sieve, specifically designed to trap invisible carbon particles in the exhaust. The key is that it has a self-regeneration function: when the system detects too much carbon buildup, it injects extra diesel to heat up the exhaust pipe and burn off the deposits. But if you're stuck in traffic every day, crawling along slowly, the exhaust temperature won't rise enough, and the system fails. When this happens, engine power can drop by 30%, and fuel consumption can increase by two to three liters. I have clients who end up visiting the dealership every month because of this. Actually, just taking a 30-minute highway drive regularly to heat up the exhaust can often solve the problem. Also, it's important to choose engine oil with low ash content, otherwise, clogging becomes more likely.
