i have been trying to find out some information about this. It has been going on for a while. We took it in to the shop. They said they cleaned all the wires and that car was starting and everything. Well its been about a month, i was driving and the speedometer turned off. Well i got to where i was going and i went to leave and my car wouldnt start and it said immobilizer failure. So i got a ride and went back later and it started. any information please. Its a 2003 saab linear 9-3.
