The S68 twin-turbo setup can develop bearing damage with insufficient lubrication. Oil starvation is a frequent cause, especially with hot-soaking after hard driving without a cool-down period.

Symptoms: Turbo lag, unusual noises, power loss, whistling noise

The S68 cooling system is complex and can develop leaks at hoses, thermostat and radiator. Overheating damage is particularly serious given the high power output.

Symptoms: Coolant loss, temperature warning, steam from the engine bay

The BMW S68 V8 biturbo exhibits elevated oil consumption on some units as a known characteristic. Regular oil level checks between oil changes are mandatory.

Symptoms: Oil level drops between service intervals, occasional bluish smoke

The S68 relies on extensive electronics that are prone to sporadic sensor and control unit failures. Erratic engine behaviour and warning lights without obvious cause are typical.

Symptoms: Warning lights without apparent cause, rough running, sporadic power drops

The S68 uses both direct and port injection (TVDI). Injectors can form deposits and cause rough idle.

Symptoms: Rough idle, poor fuel efficiency, occasional misfires

Software faults trigger engine management and gearbox fault messages without any mechanical defect. Particularly affects MHEV variants. OTA updates address known cases; ECU reprogramming at the dealer often necessary.

Despite the new generation, early L461s show compressor failures and faulty height sensors. ABS modulator noises addressed via OTA update. Air suspension remains inherently expensive to repair when it fails.
