I. Common Issues with Dry Dual-Clutch Transmission (DCT
1. Low-speed jerking/jolting
When frequently shifting gears in a congested area with a dry dual-clutch, the clutch plates tend to overheat, causing obvious jerks or jolts when switching between 1st and 2nd gears.
- ** Solution ** : Upgrading the TCU program can alleviate the problem, but it cannot cure it completely; Avoid following the vehicle at a low speed for a long time.

2. Abnormal wear of the clutch disc
Long-term urban driving may cause the clutch plates to wear out prematurely, which is manifested as delayed gear shifting and slow power engagement.
- ** Suggestion ** : Check the clutch plate every 60,000 kilometers and replace it if necessary
