Direct injection causes carbon deposits on intake valves. Walnut blasting may be needed. (~250–600 € repair)
Coolant reservoir or thermostat housing can develop micro-cracks. (~200–600 € repair)
HPFP can wear over time, causing rough running or hard starts. (~500–1 200 € repair)

BMW B58 inline-6 turbo petrol — B58

3.0L Petrol 326–388 к.с. Reliability: excellent Risk: 2/10 (low)

🚨 What to check before buying

Overall risk score: 6/10

Additional notes

BMW N54 3.0 twin-turbo (335i, 535i, Z4 35i): legendary performance but known for: (1) Waste gate rattle — turbo actuators wear, causing rattling. BMW dealer fix is twin turbo replacement at €3,000-5,000. (2) High-pressure fuel pump failure — sudden loss of power. €500-1,000. (3) Fuel injector failure — coking and cracking. €200-400 each, 6 total. (4) Water pump/thermostat electronic failure — €400-800. The N55 single-turbo successor is more reliable.
