Hey, I'm looking to buy my first AUDi ever! got my eye on a 2005 TT quattro 3.2. Airbag warning light is on, seller says the passenger airbag has to be replaced, there's a crease or indentation on the passenger side of the dash, but it's not ripped so the airbag has not been deployed. How much money, worst case scenario ? I'm not able to do any of the work myself.
