The dreaded "AWD and DSC malfunction" has happened to my new 2007 530xi, with less than 2000 miles on it. Does anyone who has suffered through this know the actual name and/or part number of the sensor that is supposedly responsible for this ? I am calling the dealer tomorrow morning, and from past experience it always helps to be prepared. Also, does anyone know if the sensor is on back-order and how long does it take to get one ? Thanks.
