2003 BMW X3 Battery/Warning lights

There is a possibility that the DSC control unit has either set a fault or the control module has failed and will require replacement. If you have the DSC system scanned there will be faults set, possibly for steering angle sensor calibration or front wheel speed sensor plausibility. These will need to be worked through. The plausibility faults can often be ignored, recalibrate LEW, clear faults and drive the car. (LEW is the abbreviation for steering angle sensor)
