There are at least 2 sensors that only affect DSC......steering angle and yaw rate accelerometer. The steering angle sensor error sometimes occurs after a front end alignment is performed.
Was your mate able to read the DSC module with his laptop connected? Do you know what software he was using? If your e39 has the underhood diagnostic plug you must use it, not the underdash connector, to read all modules.
The DSC light is also characteristic of having a used but uncoded DSC module installed.
