2002 BMW 530i Q&A
2002 BMW 530i Question: I have a traction control light on. How do I fix that?
First I would recommend taking your E39 to a shop that has a factory scan tool, let them diagnose the problem. The DSC light could be a number of different problems. Might be a problem with the module itself, could be a Precharge pump issue, wheel speed sensor, steering angle sensor, etc.... Basically I wouldn't disconnect anything that just might cause more problems. - marque motors
