Our 2011 Cayenne base model has indicated that the parking brake, ABS, and suspension management systems are inoperable. However, the parking brake works fine, the brakes are fine, and the drive into town yesterday was fine. The only system that was not working was the cruse control, and there was no indication from the dash data that it was having a problem. Is there anyone on the forum that knows about these things and could provide some insight into a permanent fix, or is it just a simple reset button somewhere that needs attention? The opportunity for our electronics to be zapped by incoming radio waves seems to be a problem in this age of wrenching by electronics. Thanks in advance for your assistance.
