Does the Lavida 1.5L have a particulate filter?

Volkswagen Lavida 1.5L does not have a particulate filter. A particulate filter is a ceramic filter installed in the diesel engine emission system, which can capture particulate emissions before they enter the atmosphere. Methods to check for a particulate filter: Refer to the and to see if there is a particulate filter function. Additionally, carefully check the fault codes in the manual to see if there is a "Particulate Filter" warning light indicator. Examine the label on the oil cap; if it clearly states 0W-20 grade oil, it indicates the presence of a particulate filter. Look behind the catalytic converter on the exhaust pipe for a cylindrical section—if present, that is the particulate filter. 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 pipeline. The densely arranged bag-type filter inside captures the carbon particles on a metal fiber felt filter. When the accumulation of particles reaches a certain level, the burner at the end automatically ignites, burning off the adsorbed carbon particles and converting them into harmless carbon dioxide that is then released.
As a long-time Volkswagen owner, I can confirm that the 1.5L engine in newer models like the Lavida, especially those from 2020 onwards, is mostly equipped with a particulate filter. This is mainly due to stricter national emission regulations, such as the China 6 standard requiring its installation. It's essentially a small mesh installed in the exhaust pipe to capture tiny particulate pollutants. My own car often requires highway driving to regenerate and prevent clogging issues. Maintenance is relatively simple—just avoid driving too slowly too often. It works fine, mainly for environmental protection, but frequent clogging can be quite annoying. I recommend checking the specific model year before buying a car, as newer models definitely come with this feature.
