I just purchased a 2008 SAAB 9-3 AERO cabrio with 89000 miles on it and while driving all the dash lights come on, gages stop working, and the car won't start when it's hot. I get the code U0212 for lost connection with steering module. Im extremely frustrated and the general mechanic I brought it to told me he's not familiar with SAABs. Ive been reading that it could be the CIM? Any suggestions or clues?
