🔧 Maintenance

Oil Change Interval:

Variable Service Interval Indicator (VSI) system typically suggests oil changes every 10,000-15,000 miles (16,000-24,000 km) or annually, depending on driving conditions. Consult the manual for precise BMW recommendations based on your specific model and driving habits.

Coolant Flush:

BMW recommends coolant replacement every 2-4 years or a specific mileage, often around 30,000-50,000 miles (48,000-80,000 km). Refer to the manual.

Transmission Fluid Change:

BMW historically considered transmission fluid 'lifetime' fill for manuals and sealed automatics. However, for longevity, many specialists recommend fluid and filter changes for automatics every 60,000-100,000 miles (96,000-160,000 km). Manual transmission fluid should be checked and potentially replaced at similar intervals.

Spark Plug Replacement:

Typically around 100,000 miles (160,000 km) for iridium or platinum spark plugs, but consult the manual for exact intervals and plug types (e.g., NGK BKR6EQUP).

Brake Fluid Type:

DOT 4 (BMW P/N 81 22 9 400 361 or equivalent)

Power Steering Fluid:

Pentosin CHF 11S or BMW Power Steering Fluid (P/N 32 13 1 142 575)

Cooling System:

Plastic coolant expansion tanks can become brittle and crack. Water pumps (often plastic impeller) are a common failure point. Thermostat housing leaks. Vanos (Variable Valve Timing) solenoids and seals can cause rough idle or performance issues.

Suspension:

Front control arm bushings (bushings separate from the arm are common replacements), rear subframe bushings, and sway bar links are wear items that can affect ride quality and alignment.

Electrical:

CCFL angel eye rings (if equipped) can fail. ABS/DSC sensor failures. Pixelation in the instrument cluster display. LCM (Light Control Module) issues.

Engine:

Oil pan gasket leaks. Valve cover gasket leaks. CCV (Crankcase Ventilation) system issues leading to oil consumption or leaks.
