⚙️ Engines — what to expect
BMW/PSA petrol turbo — N13
Known issues
- Similar chain tensioner issues to N47 though less severe. Listen for rattling. (~1 200–2 500 € repair)
- Wastegate develops play, causing rattling noise under boost. (~400–1 000 € repair)
BMW N-series petrol turbo — N20
Known issues
- Chain guides and tensioner wear, causing chain to stretch. Rattling on startup is the telltale sign. (~1 500–3 000 € repair)
- Common oil leak point. If ignored, oil can drip onto serpentine belt. (~150–400 € repair)
- Plastic charge pipe can crack under boost. Aftermarket aluminum pipe is a permanent fix. (~150–500 € repair)
- Electronic water pump fails — common BMW issue across N-series engines. (~300–700 € repair)
- Wastegate actuator develops play, causing rattle and potential boost control issues. (~400–1 200 € repair)
BMW B-series 3-cylinder petrol — B38
Known issues
- 3-cylinder engines have inherent vibration — this is normal, not a defect. Engine mounts wear faster compensating for imbalance. (~0–300 € repair)
- Chain tensioner can lose pressure after cold soak, causing brief rattle on startup. Usually harmless but should be monitored. (~500–1 200 € repair)
- Plastic expansion tank can develop hairline cracks. Slow coolant loss without visible external leak. (~100–250 € repair)
🚨 What to check before buying
Overall risk score: 9/10
Serious risks
- Timing chain stretch: Similar chain tensioner issues to N47 though less severe. Listen for rattling.
- Turbo wastegate rattle: Wastegate develops play, causing rattling noise under boost.
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.
