Has the 2022 Tiguan L's Particulate Filter Clogging Issue Been Resolved?

[McCayden]

Currently, the official has not addressed the particulate filter clogging issue in the Tiguan L, but dealerships have proposed solutions. Solutions for particulate filter clogging: Drive more on highways, for example, when driving at 80km/h, suddenly accelerate to 120km/h, then reduce back to 80km/h and repeat several times. This keeps the engine under high load, raising exhaust temperatures to oxidize and clear the particulate filter internally; shift the vehicle to neutral and rev the engine to 3000-4000 RPM to increase exhaust temperature, thereby regenerating the particulate filter; avoid short trips and traffic congestion to prevent particulate filter clogging. Effects of particulate filter clogging: Reduced vehicle power—some models automatically reduce engine power output if particulate filter clogging is detected. Increased exhaust resistance also weakens vehicle performance; higher fuel consumption—clogging increases exhaust resistance, weakening power and forcing drivers to press the accelerator harder and drive at higher RPMs, leading to increased fuel consumption.
