BMW DIFFERENTIAL FLUID SERVICE
Differential fluid works under constant load and heat, especially in higher-performance, xDrive, and M vehicles. As the fluid ages, its ability to lubricate and protect internal components can diminish.
Service intervals vary by model, drivetrain, and vehicle use. Cars driven hard, tracked, or equipped with limited-slip differentials may benefit from more frequent service than lightly driven street cars.
We drain and refill the differential with the correct BMW-compatible fluid, inspect the old fluid for unusual contamination or metal, and check for obvious leaks or concerns around the differential housing.
Differential fluid lubricates the gears and bearings that transfer power to the wheels. Replacing aged fluid helps reduce wear, control heat, and keep your BMW’s drivetrain operating smoothly.
