It occurs sometimes when I try to start the car. It acts like a dead battery and won't start.
It will not start and says alarm system service required on 2006 Volvo S40
Similar thing happened to my car, alarm service required has been on for a couple months and it occasionally won't start. Now all my sensors have gone haywire and Volvo hasn't figured out the problem after a week... What was wrong with your car in the end?
