Brake Fluid Change:

Every 2 years, regardless of mileage (DOT 4 LV high-performance brake fluid recommended).

Cabin Air Filter:

Annually or as per CBS recommendations.

Engine Oil Sdrive28I:

SAE 0W-30 or 0W-40, BMW Longlife-01 (LL-01) or BMW Longlife-04 (LL-04) approved synthetic oil.

Engine Oil Sdrive35I:

BMW Blue Antifreeze/Coolant (G48) or equivalent ethylene glycol-based coolant with corrosion inhibitors, mixed 50/50 with distilled water.

Power Steering Fluid:

BMW power steering fluid or Pentosin CHF 11S (if specified for electric power steering assist components, consult manual).

Convertible Top Mechanism:

Potential issues with hydraulic pump, seals, microswitches, or actuators for the retractable hardtop operation. Regular lubrication of seals and mechanisms is recommended.

Turbocharger Issues:

Early N54 (predecessor) and N55 engines could experience turbo wastegate rattle or actuator issues. Proper warm-up and cool-down procedures are crucial for turbo longevity. Inspect for oil leaks.

Valvetronic Actuator:

The Valvetronic system can develop issues with the eccentric shaft sensor or actuator motor, leading to rough idling or performance problems. Diagnostic codes are critical here.

Water Pump:

Electric water pump on N20 and N55 engines can fail over time, leading to overheating. Monitor coolant temperature closely and listen for unusual pump noises.

Ignition Coils And Spark Plugs:

Common wear items that can cause misfires. Regular replacement as per schedule is advised.
