What is the cause of Volkswagen's dual-clutch transmission failure?

[WilliamDella]

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.
