Does the 2021 Tayron Still Have Clogging Issues?

The 2021 Tayron is equipped with a China 6B-compliant engine that includes a particulate filter, which may still be prone to clogging. Reasons for Tayron's clogging issues: The vehicle is fitted with a particulate filter. This device is typically integrated inside the three-way catalytic converter, forming a four-way catalytic system. Its primary purpose is to help the vehicle's exhaust meet China 6 emission standards by filtering fine solid particles, essentially acting as a mask over the three-way catalytic converter. Over time, accumulated particles can gradually cause blockages, eventually leading to exhaust flow obstruction, which explains the Tayron's similar issues. Methods to prevent Tayron clogging: Owners can mitigate this by frequently driving at highway speeds. This is because high temperatures generated during standard driving conditions facilitate the regeneration of the particulate filter. Additionally, owners can take measures such as using low-ash engine oil, high-quality fuel, and regularly replacing the air filter. No single measure can completely resolve clogging; only a combination of these approaches can effectively prevent the issue.

I'm the owner of a 2021 Tiguan, having driven it for over two years now. Initially, the car frequently experienced particulate filter clogging, with fuel consumption soaring above 12 liters and a noticeable drop in power. The main cause was too much low-speed driving, preventing the automatic burning off of accumulated exhaust particulates. After driving 30,000 kilometers, I took it to the dealership for a free software upgrade. Now, I make sure to drive at high RPMs on the highway once a week, and the clogging issue has basically stopped. Volkswagen later optimized the exhaust system design in the 2022 model, so early batches of the 2021 model might still carry some risks, but the situation improved significantly after the update. I recommend owners pay attention to their driving habits—avoid getting stuck in city traffic too often, use the S mode or manual mode to keep RPMs above 2500 for a few minutes, and regularly maintain and check the software version. The car is spacious and stable, but dealing with this issue requires a bit of extra effort.

As an auto mechanic, I've repaired numerous particulate filter failures in the 2021 Tayron models. Common symptoms include abnormal fuel consumption increase, dashboard warning lights, and sluggish acceleration. This stems from insufficient regeneration at low speeds causing clogging. The solution usually involves ECU software updates to enable more frequent regeneration or manual ash cleaning. Volkswagen has a free service campaign, so owners should promptly visit authorized dealerships for fault code diagnosis and program upgrades. While there haven't been major hardware changes, post-software optimization the clogging rate has significantly decreased. For daily driving, avoid frequent short trips and drive more on highways to trigger active regeneration as prevention. If severely clogged, the filter requires disassembly and cleaning - costly but early intervention saves hassle. Such issues are common among domestic SUVs too, but Tayron handles it relatively well.

Regarding the issue of the 2021 Tiguan L getting clogged, Volkswagen's early design indeed had flaws—the particulate filter was prone to clogging due to low-speed driving, leading to a surge in fuel consumption. However, feedback from car owner groups indicates that the software update rolled out in mid-to-late 2021 resolved about 80% of the problem. If you're driving an updated version or frequently take highway trips, it should be fine. Otherwise, those who mainly drive in urban areas might still encounter the issue. The 2022 model has undergone exhaust system recalibration, which has basically eliminated the problem. If opting for a used car, check if the software is up to date—otherwise, the risk remains high. Volkswagen's reliability is decent but not perfect; it's advisable to test-drive thoroughly and clarify the vehicle's condition before making a decision.
