The dreaded DSC problem with the E39, E46 and E38 model BMW is  an extremely common one. The main symptom is that your DSC – or dynamic stability control- light may come on for a few minutes and then go away at random times. Eventually, the DSC light will stay on, no matter how many times you turn the car on and off or push the DSC button. You may also have the ABS or BRAKE warning lights on at the same time.
