My LED (reminder) had not lit up until now. Last time in the service I criticized this and a software adjustment was made and now it flashes. (Probably my predecessor has deactivated it) In addition, the Garagist told me that the alarm system was disabled and is now switched on again. It was new to me that my V40 T2 (Bj 99) has an alarm system. How can I find out? What I know for sure that my Volvo has Deadlock. The Garagist could do not give me any further information about the alarm system, except that you start raising the car.?.? How do I test whether the alarm system really works, or, is there? Merci for the help
