Which Volkswagen models do not have a particulate filter?

Volkswagen Passat does not have a particulate filter. Function of particulate filter: The particulate filter can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Application technology of particulate filter: The particulate filter utilizes advanced electronic control systems, catalytic coatings, and fuel additive catalysts. Principle of 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 engine exhaust particulate trap through a dedicated pipeline. After passing through its densely arranged bag-type filter, the carbon particles are adsorbed on 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 emitted.
Regarding the question of which Volkswagen models do not have a particulate filter, I remember that before the full implementation of the China V emission standards, many older models like the Golf or Magotan from around 2017 might not have been equipped with one, as the regulations were not as strict back then. The particulate filter is mainly designed to capture fine particles in the exhaust. If the car predates the China VI emission standards, especially older models found in the used car market, there's a good chance they don't have one. Of course, nowadays, new cars are almost always equipped with GPF as standard. If you're looking for models without a GPF, it's advisable to check the production year—for example, pre-2019 Passat or Lamando models might be more common. In short, don't worry too much about GPF maintenance. While older cars may not meet current emission standards, they are indeed more hassle-free to drive—just make sure to have the exhaust checked regularly.
From a technical perspective, the application of particulate filters (GPF) in vehicles has become widespread since the implementation of China's National VI-b emission standards. Volkswagen, for instance, has equipped almost all its new models with GPFs post this regulation. However, if you're asking which models don't have them, it's primarily older National V emission-compliant cars, such as entry-level versions of the 2016-2018 Lavida or Sagitar. With the change in emission rules, GPFs have become a mandatory component aimed at reducing pollution. That said, some imported models or older versions sold in specific regions might be exceptions. I recommend checking the car's manual or year identifier to confirm and avoid pitfalls. Overall, understanding emission standards is crucial when selecting a car. Older cars might be cheaper initially, but in the long run, they don't hold their value as well as newer, more environmentally friendly models.
