hopefully others with the same car (I've got a 2008 V8, not the V6) will chime in, but looking further, you have a timing chain, which I believe is there for 'live' in the car and doesn't need changing unless it's showing issues (ie, rattling).
So you might be safe without having to do that.
Here is something that I just found that is interesting from Audi.
It shows what is a minor and major service, so you can check against your service records to see what has and has not been done. I would assume that if your car was taken to audi for it's regular service intervals, all the stuff in this pdf would have been done, but you can always ring them to check.
