Get the oil changed to synthetic if it isn't already and change it often. Every 3000 miles is best for turbos - every 5000 for the others.

Any other advice depends on which engine you have... Which engine did you get?

 

It's 2.8Q 30 v with trip shift. sport package i belive. no turbo

 

Here's an idea for the long run...
Register your car at Audi of America.
Go here: Audi USA
If you register with the "My Audi" feature, it lists all the maintenance intervals for your year, plus all the items that should be done for each service as well.

 

Have your Control Arms and their bushings checked.
Audi's are notorious for CA issues.
