What is the cause of Volkswagen's dual-clutch transmission failure?
2 Answers
Fixed accumulator threads may crack, leading to a drop in oil pressure. Below is relevant information: 1. Introduction: Dual-clutch transmissions are widely used in current automobile production, especially dry dual-clutch transmissions, which are extensively employed in many mid-to-low-priced models. 2. Reason: The manufacturing cost of dual-clutch transmissions is relatively low. In the increasingly competitive automotive market, cost-saving is a consideration many automakers cannot ignore. Cost-saving leads to compromised quality and the inherent shortcomings of dual-clutch transmissions, resulting in more frequent occurrences of common failures. 3. Solution: Whether it's a dry or wet dual-clutch transmission, try to avoid prolonged driving in congested areas to reduce the failure rate and extend the transmission's service life.
I have repaired many Volkswagen dual-clutch transmission failures and found that the core issues are often premature wear or damage to the clutch plates, caused by frequent engagement of the friction plates in traffic jams and low-speed driving, leading to overheating. There are also software bugs in the control module—older Volkswagen models often had defects that resulted in recalls. Hydraulic system leaks can reduce oil pressure, affecting gear shifts. Insensitive sensors can cause jerks and delays. These issues are all related to the design, as the dual-clutch structure is complex and prone to overheating. I recommend that owners change the transmission oil every 40,000 kilometers, avoid sudden acceleration, shift to neutral when parked to reduce friction, and visit a specialized repair shop immediately if they notice any shaking or unusual noises—don’t wait until a major repair costing thousands is needed.
