Does Volkswagen's Dual-Clutch Auto Hold Damage the Clutch?
2 Answers
Volkswagen's dual-clutch auto hold does not damage the clutch. The auto hold system, known as AUTOHOLD, works in conjunction with the electronic parking brake to achieve the auto hold function. The auto hold feature does not cause harm to the dual-clutch transmission components or the dual-clutch plates when activated, as it primarily operates during idling or in situations like uphill/downhill traffic congestion. The working principle of the dual-clutch transmission involves the mechatronic control unit to facilitate gear shifts. When stopped at a traffic light or on an incline with the gear in D (Drive), the transmission, through data exchange between the ABS and the auto hold control unit, allows the transmission to remain in a semi-engaged state. In this state, the clutch is not engaged; it only starts working when the transmission control unit receives an acceleration signal from the throttle pedal.
As an experienced mechanic who frequently works on Volkswagen cars, I find the auto-hold function quite convenient to use, and under normal circumstances, it doesn't cause excessive wear to the clutch. This system primarily relies on electronically controlled braking. Once the vehicle comes to a complete stop, the clutch fully disengages to avoid direct friction. Although there might be a slight clutch slip during take-off, the wear is minimal. Especially with Volkswagen's wet dual-clutch system, which is lubricated by oil, making it more durable than dry clutches. The key is to pay attention to driving habits, such as avoiding prolonged parking on steep slopes, as excessive pressure on the clutch could lead to premature wear. For daily urban commuting, there's generally no issue, and regular transmission checks and oil changes can prevent most problems. Overall, just avoid unnecessary strain on slopes, and the clutch's lifespan largely depends on overall usage and maintenance.
