Additional notes
- TIMING CHAIN WARNING: M62 has a problematic timing chain design. Get it checked before buying.
- Older BMW with 200k+ km will likely need suspension refresh (control arms, bushings: €600-1,200), possibly cooling system components (water pump, thermostat: €300-700), and various sensor replacements. Budget accordingly.
- Pre-1998 BMW M62 V8 has Nikasil bore coating that degrades with high-sulphur fuel (common in E.Europe). Causes compression loss and rough running. Engine rebuild or replacement needed. Check compression on all 8 cylinders.
- Vehicle is 15+ years old. Age-related issues: rubber seals/hoses degrade, electrical connectors corrode, suspension bushings wear. Not specific to any engine, but expect €500-1,500/year in age-related maintenance beyond normal service items.
