I just recently purchased a 2007 Audi A4 2.0T Quattro. I know how to work on cars, however this is my first Audi. It does have some problems such as the airbag light is on, it needs a new oxygen sensor, and lastly a new seatbelt. If anyone has any suggestions for any of these problems it would really help.

 

Your BEST INVESTMENT is to buy a Bentley Manual.You can find them on
Amazon,either in book form or CD.It will be about $95 but well worth it.
A VAG connector for a laptop would be a good purchase as well(with Ross Tech installation)
Your question needs to be more specific concerning your car issues.Need the codes!
Hope this is a good starting point.

 

Okay do you happen to have any links to the VAG connector?

 

Again check Amazon...Are you in the States Jacob?
