Does the Tayron 330 have a particulate filter?

The Tayron 330 is equipped with a particulate filter. The Diesel Particulate Filter (DPF) is a ceramic filter installed in the exhaust system of diesel engines, designed to capture particulate emissions before they enter the atmosphere. Its function is to filter out tiny particles from the exhaust gases. Once a certain accumulation level is reached, it automatically burns off the captured particles, enabling a continuous working cycle. The diesel particulate filter effectively reduces particulate emissions by first capturing the particles from the exhaust and then oxidizing them, thereby regenerating the filter. The regeneration of the filter refers to the process where, during prolonged operation of the DPF, the accumulation of particles gradually increases, leading to higher backpressure in the engine and a decline in performance. Therefore, it is necessary to periodically remove the deposited particles to restore the DPF's filtration efficiency. A clogged particulate filter can reduce vehicle power. Some vehicle models, upon detecting a clogged particulate filter, will automatically reduce the power output of the diesel engine. Additionally, significant exhaust backpressure can also weaken the vehicle's power performance.
I've been driving the Tayron 330 for over two years now. Since the implementation of China's National VI emission standards, most of these vehicles come equipped with a particulate filter. My 2020 model has one, and so does my friend's car purchased last year. It's mainly due to stricter environmental regulations—without it, the vehicle wouldn't pass the particulate emissions test. However, this device has a downside: frequent low-speed city driving can cause it to clog, leading to a sudden increase in fuel consumption and reduced power. Once, a filter-like warning light appeared on my dashboard, indicating it was clogged. The solution is to drive at high speeds for about half an hour to raise the exhaust temperature for automatic cleaning. Owners who primarily use their cars for short commutes should pay extra attention and ideally take regular drives on highways. Of course, the specifics depend on your car's manufacturing date—the most reliable way is to check the configuration table in the vehicle's manual.
As a long-time service provider for Volkswagen, we've disassembled quite a few Tiguan 330 models. The China VI-compliant 330 versions almost all come equipped with a particulate filter, located in the middle section of the exhaust pipe, resembling a metal can. Its working principle is actually simple - it filters carbon particles from the exhaust gases, but frequent city driving in congested conditions can easily cause clogging. Last month, a car owner complained about their fuel consumption suddenly jumping from 8.5L to 13L, and upon inspection, the particulate filter was found to be 90% clogged. There are two treatment methods: for mild clogging, the owner can drive on highways to trigger automatic regeneration; for severe clogging, it needs to be removed and the accumulated carbon burned off using high-temperature equipment. We recommend owners check the engine oil every 5,000 kilometers and must use low-ash oil with VW50800 certification, otherwise it will accelerate clogging.
If you pay attention to environmental data, you'll find that the Tayron 330 has been equipped with a particulate filter as standard since the implementation of China's National VI emission standards in 2019. I once checked the vehicle filing catalog on the environmental protection bureau's official website, and all 330 models were marked with GPF devices. This device is very effective in reducing PM2.5 emissions by trapping exhaust particles in a ceramic filter. However, there's a design flaw: regeneration requires temperatures above 600°C, which is difficult to achieve in urban driving. Here's a reference data point: maintaining 80 km/h continuously for 30 minutes is required to complete the cleaning cycle. If you frequently drive in congested areas, it's recommended to drive on intercity highways at least once a month. Additionally, the failure rate is higher in low winter temperatures, so northern owners should be especially cautious.
