🚨 What to check before buying
Overall risk score: 9/10
Serious risks
- VANOS solenoid failure: VANOS variable valve timing solenoids wear out — causes rough idle, loss of power, and check engine light.
- Valve cover gasket oil leak: Valve cover gasket leaks oil onto exhaust manifold — burning smell and smoke. Common age-related failure.
- Eccentric shaft sensor failure: Valvetronic eccentric shaft sensor fails — causes limp mode. Common on high-mileage N46 engines.
- Car is 15 years old — expect age-related wear: rubber seals, bushings, water pump, AC compressor
- Higher mileage (195,953 km) — check for timing system condition, turbo health, and suspension wear
Additional notes
- BMW N20 timing chain stretches after 80k km. Rattle on cold start is the first sign. If ignored, chain can jump timing causing engine damage. Replace chain preventively. Cost €1,000-2,500.
