- 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.
