There are members on here that will scan the car for you for beer tokens as such, there's a link in my sig to check whose near you or I can sell you the tool to check the light, if you intend to stick with the VAG brands, then vcds, aka vagcom, would be the ideal company for the car & this will advise of the airbag fault reason, then you can post the logs on here mate & we can advise as much as possible as to the reason for the issue, which will then possibly allow you to resolve by yourself, thus saving a kings ransom.
