Transmission Fluid Service:

BMW initially claimed 'lifetime' fluid for the 6HP transmission, but industry best practice and owner experience suggest a fluid and filter change every 60,000-100,000 miles is advisable for longevity.

Spark Plug Replacement:

Approximately every 60,000 miles for the N73 V12 engine. Specific interval may vary.

Coolant Flush:

Every 2-4 years or as indicated by CBS.

Engine Coolant:

BMW Blue Antifreeze/Coolant (G48) or equivalent ethylene glycol-based coolant with silicate inhibitors.

Brake Fluid:

Known Issues Ignition:

Coil-on-plug ignition systems can be a source of misfires, especially with age. Spark plugs require replacement at specific intervals.

Known Issues Cooling:

Plastic coolant expansion tanks can become brittle and crack, leading to leaks. Water pump and thermostat issues can also occur.

Known Issues Electronics:

The iDrive system can experience glitches or failures. Various sensors and control modules are complex and can fail.

Known Issues Suspension:

Adaptive Drive systems (Active Roll Stabilization, Electronic Damper Control) can develop leaks or actuator failures, which are costly to repair.
