Service Intervals General
Oil Change Interval:
Typically every 10,000-15,000 miles or 12-24 months, based on BMW's Condition Based Service (CBS) system and driving conditions. Refer to manual for specific CBS sensor status.
Microfilter Replacement:
Every 20,000-30,000 miles or 24 months.
Spark Plug Replacement:
Around 60,000 miles for N55 engine, higher for N63 V8. Refer to manual for precise interval based on engine type and variant.
Brake Fluid Flush:
Every 2 years regardless of mileage.
Engine Oil 640I:
BMW Longlife-01 (LL-01) or BMW Longlife-04 (LL-04) compliant synthetic oil, typically 0W-30 or 5W-30. Refer to manual for exact viscosity and spec.
Engine Oil 650I:
BMW Longlife-01 (LL-01) compliant synthetic oil, typically 0W-40 or 5W-40. Refer to manual for exact viscosity and spec.
Coolant:
BMW Blue Antifreeze/Coolant (G48 specification or equivalent).
Transmission Fluid 8Hp:
Specialized ZF Lifeguard Fluid 8 (or equivalent specified by ZF/BMW for the 8HP transmission). This is a lifetime fluid but replacement is recommended at higher mileage (e.g., 100,000+ miles) or per service indications.

N63 Engine Common Complaints:
Historically, early N63 engines (pre-2012/2013 'TU' updates) had issues with oil consumption, carbon buildup on intake valves, and injector failures. The 2012 models likely have the 'TU' (Technical Update) which addresses some of these but meticulous maintenance is still key. Water pump failures and turbocharger issues can also occur.
N55 Engine Common Complaints:
Water pump and thermostat failures are relatively common. Charge pipe failures can occur, leading to boost leaks. VANOS solenoid issues can also arise.
Electronics And Modules:
Various electronic control modules (e.g., DME, TCU, PDC) can fail or develop intermittent issues. Battery degradation can affect numerous systems.
Suspension And Steering:
Wear in suspension bushings, ball joints, and tie rods can occur with mileage. Power steering system leaks or electronic power steering component failures can also happen.
