I understand from The Auto Pool that the air mass meter is a common problem on Audis generally - just had it replaced on my S6, for example. It throws up random fault codes though, so unless you are aware of the issue it's not easy to diagnose. One of the things it does do is to activate the ESP unnecessarily so it would be worth taking your car out for some serious throttle abuse and seeing it the light comes on.
