Is the 2021 Tayron Still Experiencing Blockage Issues?

2021 Tayron's particulate filter has been upgraded and currently does not experience blockage anymore. Definition of Particulate Filter: A particulate filter is a ceramic filter assembled in the diesel engine exhaust system, capable of reducing over 90% of soot emissions caused by diesel engines. The design principle of the particulate filter involves adsorbing carbon soot particles onto the filtering device, and when the adsorption reaches a certain level, the accumulated carbon soot particles are burned off. Function of Particulate Filter: Installed in the engine emission system, the particulate filter captures particulate emissions before they enter the atmosphere. The captured particulate emissions are then burned off during vehicle operation, effectively improving the vehicle's exhaust quality.
I previously drove a 2021 Tiguan L, and back then, I often encountered issues with the DPF (Diesel Particulate Filter) getting clogged, especially after frequent short-distance city driving. The main reason was that the diesel engine didn't reach sufficient temperatures during low-speed driving, causing rapid particle accumulation and preventing the system from performing automatic regeneration. Later, I learned that Volkswagen released a software update to address this issue, reducing the frequency of clogging, but it was still quite common in the original 2021 version. The solution is quite simple: drive at high speeds for about 30-40 kilometers weekly, keeping the engine RPM above 2,500, which can trigger passive regeneration. If the clogging is severe, it's best to visit a 4S dealership for active regeneration or a hardware check. Driving habits play a significant role—try to avoid frequent stop-and-go driving. Overall, the 2021 Tiguan L isn't perfect when it comes to clogging issues, but it's manageable. Don't worry too much; with proper maintenance, it's still a comfortable ride.
The DPF clogging issue in the 2021 Tayron does exist, and I personally feel it's more pronounced in early production batches. The root cause lies in the exhaust treatment system design - the particulate filter tends to accumulate carbon deposits if not cleaned promptly. Solutions can be approached from two angles: either use cruise control more often to maintain steady high-speed driving, or manually initiate the regeneration procedure when parked. Volkswagen later provided free software updates that alleviated many users' troubles, though the base 2021 models still carry some risk. I'd recommend opting for the gasoline-powered Tayron, which rarely experiences similar issues. Additionally, regular oil changes and air filter replacements can serve as preventive measures - don't cut corners to save money. For used car buyers, always check maintenance records to confirm system upgrades and avoid purchasing problematic vehicles. In summary, the issue is manageable but requires some patience.
