Onset 60,000-130,000 km. The dry-clutch packs themselves also wear, often by 80,000-150,000 km.
Common Symptoms
- jerky shifts
- refusal to engage

How to Fix
Mechatronic replacement (refurbished unit + coding) €900-€1,800; new €2,000-€3,000. Dry clutch pack replacement €1,200-€2,000. Some markets had VW extended-warranty coverage — check records. Avoid riding the brake on inclines (DQ200 hates it).
