Pump failure will for sure bring on an ABS light. With the engine off, key off, press the brake pedal 20 times turn the engine on you should hear the brake ABS pump run if not the pump has actually failed or there is a problem wiring issue, fuse ect.... I am not experienced enough i=with the BMWs' to say I have seen pump failures as a common BMW problem.

hi! i just did as per your instruction i pressed brake pedal 20 times key off. then i switch on 2 times i did but i did not hear any sound coming from the ABS pump. now i'm sure that the ABS pump motor actually failed. thanks for the information it is very helpful to all car owners. thanks

warning! the control unit is attached to the pump and nine times out of ten, a pump won't fix this, it's usually the controller. a well qualified BMW shop can test to see which is which because the symtoms are identical.
