Moin an alle! Zum Elch: v40 bj 2004 Gasoline 1,8. Zu meine Problem: My airbag light always starts once a year. For the TÜV I always had the error memory deleted and good. It was always on the plug from the passenger seat.. This time the workshop told me that there are three faults (also the plug) which can not be deleted any more. Nu said the mechanic, that the control unit is defective, that can lie on it that I had once disconnected the battery. What do you say, can it be? New device probably costs 1000€. That can not be anything, or what do you say? Be very happy about tips and experiences of you.
