So i've been looking at the post and can't seem to fing any help. My 04 A4 Airbag light comes on every time the rear seat belt is pulled out. The seat belt doesn't even have tobe clicked inif you just pull it out the light goes off. its onlythebeltbehind the driver seat. I don't know what to fix. the whole belt or i've heard the tensioners.Please help

there is nothing you can do. you have to replace the whole belt assembly and its not cheap. if you have a good relationship with the dealer they might cover it or discount it due to safety. warrarnty is screwy, i am a tech and dont know all the coverage aspects.
