- Replacement Interval80,000-120,000 mi
Timing Chain Maintenance Critical
The R32's dual-VVT timing system is complex with multiple chains and tensioners. Chain guide wear causes startup rattle that worsens over time. Inspect at 80,000 miles - chain replacement requires transmission removal (12-20 hours labor). Budget $2,000-3,500 for parts and labor.
