"The system is active and governs drive and braking force. The warning lamp comes on and stays on while driving:
DSC has been switched off with the button.
If, after repeatedly pressing the DSC button, the warning lamp still does
not go off, then that means that the DSC, HDC and the vehicle's roadholding
ability are defective.
Please have the system checked by the nearest BMW center."

Did you try pressing the button?
