BMW marketing calls many fluids “lifetime,” but heat, time, and real-world driving tell a different story. In this Under the Hood episode, we dive deep into what every BMW owner should service after the factory cover ends: automatic gearbox oil, differential and transfer case fluids, brake fluid, coolant, steering hydraulics, belts, and more.
Discover why changing “sealed-for-life” fluids at the right intervals can prevent gearbox wear, differential noise, overheating, and expensive repairs later on.
We also share ZF’s real recommendations, BMW’s overlooked intervals, and simple checks that extend the life of your engine and drivetrain.
