Most common problem of the DSC/ABS and Brake light up is caused by malfunction of sensors like speed sensors, ABS pulse sensors or steering wheel angle sensor. However, you must have it diagnosed with BMW DIS system to read the fault code so that you can tell what the problem is. Replacing speed sensor or steering wheel sensor is very simple job and the part is not expensive, but code is needed to make the sensor work. Replacing DSC/ABS module repair kit is also very simple job, but the part is pretty expensive and it must be coded after replacement to make it work and must be adjusted to make it work with steering angle sensor and other sensors.
