Volkswagen Tiguan's particulate filter experiences clogging issues. According to feedback, the clogging of the Volkswagen Tiguan's particulate filter can lead to a significant surge in vehicle fuel consumption, even reaching up to 40L per 100 kilometers. Additionally, the clogging of the particulate filter also causes exhaust system malfunctions, reduced power, and failure of the start-stop system. Below is some information about the particulate filter: 1. Introduction: The Diesel Particulate Filter (DPF) is a ceramic filter installed in the diesel engine's emission system, which captures particulate emissions before they enter the atmosphere. 2. Function: The particulate filter can reduce the soot produced by diesel engines by more than 90%. The captured particulate emissions are subsequently burned off during vehicle operation, effectively reducing particulate emissions.
