Regular service intervals during the initial 30,000 miles are critical to maintaining your BMW's peak condition:

• 10,000 miles:

  Replace engine oil, oil filter, and check coolant levels. A comprehensive vehicle inspection and tire rotation are also performed if necessary.

• 20,000 miles:

  Inspect and replace fuel filters, along with a repeat of the 10,000-mile service. The CBS system is also reset during this service.

• 30,000 miles:

  Major vehicle inspection that includes checking the HVAC system, exhaust, and suspension systems. Replace brake fluid, and for manual-transmission BMWs, replace the transmission fluid.

As your vehicle ages, maintaining its dynamic performance and safety becomes crucial:

• 40,000 miles:

  Engine oil change, brake system inspection, spark plug replacement (if applicable), and tire rotation.

• 50,000 miles:

  Thorough inspection of engine components and safety systems, including driver assistance sensors and cameras.

• 60,000 miles:

  Comprehensive service similar to the 30,000-mile check, with additional inspections on transmission components and drivetrain. Replace engine air filter and inspect and replace brake pads and brake rotors as necessary. For automatic-transmission BMWs, replace the transmission fluid.

Maintaining high standards of luxury and performance in high-mileage BMWs requires detailed attention:

• 70,000 miles:

  Repeat of the 40,000-mile service, with additional focus on suspension components and electronic systems.

• 80,000 miles:

  Check and replace cooling system components, inspect the fuel system, and conduct additional diagnostics as per CBS alerts.

• 90,000 miles:

  Major inspection and replacement of wear-and-tear parts like hoses, belts, and additional filters. Replace timing belts and hoses as needed.

Continuing comprehensive and preventive maintenance is vital for BMWs that surpass 90,000 miles:

• Post-90,000 miles:

  Adhere to the 5,000-mile maintenance schedule and repeat the maintenance intervals listed above. Continue monitoring and replacing parts as recommended by the CBS system, with particular attention to engine and transmission health and updating any outdated electronic modules.
