Does the Volkswagen Tharu have a particulate filter?
2 Answers
Volkswagen Tharu is equipped with a particulate filter. The particulate filter is located behind the three-way catalytic converter and in front of the muffler, surrounded by front and rear oxygen sensors. Function of the particulate filter: The particulate filter can reduce the soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. 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 trap through a dedicated pipeline. 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, burning off the adsorbed carbon particles and converting them into harmless carbon dioxide that is then released.
I've been driving the Volkswagen Tharu for a while now, and it indeed comes with a particulate filter. I remember the salesperson mentioning during purchase that it helps filter out pollutants from the exhaust to meet environmental standards. I've actually encountered minor issues with it, like one winter when driving at low speeds for too long triggered a dashboard warning light indicating blockage. I had to quickly take it on a highway run to let it automatically clean. This system is great for reducing smog emissions, and regular maintenance is all it takes. It's not a big deal—many Volkswagen models now come equipped with this, especially new cars sold in big cities. If any issues arise, checking the sensors or getting it cleaned at a 4S shop usually resolves things quickly, so no need to worry too much.
