If you are familiar with bleeding brakes you may be fine. Go slowly and carefully. If you draw air into the circuit by letting the master cylinder get too low the air can get trapped in the ABS controller. There are dead ends, valves, and actuators there. If air does get in there you need to use the BMW service computer to cycle the ABS valves while bleeding. It can be frustrating, and a challenge. Good luck.
