Hi. Posted about this a few times before but havent yet got it fixed. Does anyone know where the alarm siren is on a 17 plate A class? The only way i can stop my alarm going off when it’s locked is to manually lock it with the key. i don’t really want to remove the siren but my dads a mechanic and has absolutely no clue. was taken to a ‘mercedes specialist’ paid 50£ for him to tell me i’m not closing the doors properly! And was taken to another garage who had no clue.
