Oil Change Interval:
Typically every 7,500 to 10,000 miles (12,000 to 15,000 km) or annually, whichever comes first. Consult manual for specific conditions.
Transmission Fluid Interval:
BMW recommended fluid changes at longer intervals (e.g., 60,000 miles or more), but many recommend earlier changes (30,000-50,000 miles) for longevity.
Coolant Change Interval:
Typically every 2-3 years or 30,000-50,000 miles.
