What are the causes of transmission abnormalities in the SAIC Volkswagen Tiguan L?

The causes of transmission abnormalities in the SAIC Volkswagen Tiguan L are: 1. Wear and damage of bearings; 2. Wear of transmission components or the use of low-precision replacement parts; 3. Insufficient lubrication due to inadequate or overly viscous lubricating oil; 4. Loose bolts on the transmission housing; 5. Long-term failure to replace automatic transmission fluid. Taking the 2021 SAIC Volkswagen Tiguan L as an example, it is a mid-size SUV with the following dimensions: length 4712mm, width 1839mm, height 1673mm, wheelbase 2791mm, fuel tank capacity 60L, and curb weight 1650kg.
Our family drives a Tiguan L, and a while ago, there were some issues with the transmission—it had noticeable jerks when decelerating. After getting it checked, the mechanic said the transmission fluid had aged, and not changing it for too long led to excessive impurities clogging the system. The DSG transmission in Volkswagens is quite sensitive; dirty fluid can easily cause malfunctions, and there’s also a possibility of faulty control unit sensors or worn clutches. I usually change the fluid every 40,000 kilometers to prevent many issues. That repair cost quite a bit, but the car runs much smoother now. My advice is to get it checked at a professional shop as soon as you notice abnormal noises or rough shifting—don’t wait until you need a whole new transmission, as that would really hurt your wallet.
Talking about the abnormal transmission of the Tiguan L, I find it quite interesting. The DSG dual-clutch system is ingeniously designed but prone to issues, such as jerky gear shifts or failure to engage, possibly due to weak oil pumps, stuck solenoid valves, or clogged valve bodies with sludge. On the electrical side, poor wiring contacts or faulty control modules can also misinterpret signals. I once experienced a transmission overheating warning after aggressive long-distance driving, which was later alleviated by slowing down and regularly checking the fluid levels. Don't underestimate these details—gentle driving and timely maintenance can save you a lot of hassle.
