Fluids and Filters:
- Brake Fluid: Change annually to maintain braking efficiency.
- Cabin Microfilter: Replace annually to ensure clean air within the cabin.
- Engine Air Filter: Replace annually for optimal engine performance.
- Coolant: Flush and replace every 2 years or 30,000 miles.
Transmission and Differential Fluids:

- Coolant Hoses: Inspect for wear and replace if necessary every 4 years or 60,000 miles.
Long-term Component Replacement:
- Water Pump: Replace every 6 years or 100,000 miles to avoid cooling system failures.

It’s important to follow these guidelines closely and adjust based on your specific driving conditions and habits. Regular maintenance not only ensures the optimal performance of your BMW E30 but also helps in preserving its value. For detailed service procedures and to perform some of the simpler maintenance tasks yourself, consulting a repair manual can be very beneficial. This will save costs and enhance your understanding of your vehicle's operational dynamics.
