N74B60A · 760i · Used in this car from 2009-2015
Strengths
Unique character engine
Gives the sedan excellent dynamics
Watch-outs
Hard to sell a car with this engine
Most spare parts are very expensive
Prone to oil and coolant leaks
Known engine issues
Injectors and high-pressure fuel pumpThe first generation with piezo injectors is very sensitive to fuel quality, but the updated version with electromagnetic injectors is slightly less demanding. The Alusil cylinder coating also does not tolerate poor fuel and is prone to scoring.
Oil consumptionEarly engines had poor piston rings that would stick quickly, but after an update they were replaced and oil consumption now occurs at high mileage. Also, overheating causes valve stem seals to harden, leading to oil consumption.
Timing chainDue to aggressive Start-Stop system operation, timing chains can stretch by 100,000 km, and replacement is very expensive. The fuel savings are minimal, so it's better to disable this system. Infrequent oil changes lead to contamination of Vanos filters and their failure.
Listed from most frequently reported, each with its source.
Electric water pump and cooling circuit failure
Often reported
The complex V12 cooling system includes electric water pumps and sensors that can fail with age, potentially causing sudden overheating and driver warnings.
Cooling
Oil leaks from valve cover and PCV
Often reported
In large-displacement BMW engines, including V12 versions, oil leaks from valve cover gaskets and the PCV system are frequently reported.
Engine Bay
High-pressure fuel pump failure
Often reported
In the V12 biturbo (N74) engine, the high-pressure fuel pump (HPFP) can fail or malfunction, causing hard starting, fuel delivery interruption, power loss, and limp mode.
Fuel System
Turbocharger and wastegate wear/failure
Often reported
Turbochargers and their actuators/wastegates in V12 biturbo engines can cause noise, boost loss, and performance drop. This is often due to actuator wear or play in supercharger components; if neglected, it can lead to complete failure.
