Has the Particulate Filter Issue in the Tharu Been Resolved?
2 Answers
Particulate filter clogging issues still persist. Function of the particulate filter: The particulate filter can reduce soot produced by diesel engines by over 90%, with the captured particulate emissions subsequently burned off during vehicle operation. Principle of the particulate filter: The diesel particulate filter is coated with platinum, rhodium, and palladium metals. The black smoke containing carbon particles emitted by the diesel engine enters the engine exhaust particulate trap through a dedicated pipeline. It then passes through the densely arranged bag-type filters inside, adsorbing the carbon soot particles 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 soot particles and converting them into harmless carbon dioxide for emission.
As a Tharu owner, I remember the GPF (Gasoline Particulate Filter) issue was quite common in the past two years, mainly causing troubles like increased fuel consumption and reduced power due to clogging during low-speed driving. Volkswagen actually recognized this early on and later optimized it through software updates. Now many fellow car owners say the problem is basically resolved. For someone like me who often drives on highways, it's not a big issue, but I'd still recommend regularly taking the car on high-speed runs to flush the particulate filter, avoiding frequent short-distance city driving, especially during prolonged idling. Overall, driving the Tharu now feels much smoother than before. The manufacturer's response was relatively timely, and with proper daily maintenance, recurrence can be avoided.
