Brake Fluid Flush:

Every 2 years

Common Problems:

Head gasket leaks (especially on early M60 engines), VANOS system issues (though less common on the 4.0L compared to 4.4L), cooling system component failures (plastic expansion tanks, water pumps), oil pan gasket leaks, sagging headliner, E34 specific issues like door seal deterioration and corroded battery trays.

Vanos System:

Variable Valve Timing (VANOS) unit can develop leaks or solenoid issues, affecting performance and fuel economy.

Electrical Gremlins:

Due to age, wiring harnesses and connectors can degrade, leading to intermittent electrical faults.
