I brought my audi to my mechanics house and he said there was low compression in cylinder 2 and that it was 1500 to fix it. I checked all the basics and couldnt figure it out so i brought it to him. He first believed the timming belt was off and now believes it needs a valve job

Best thing to do is to do a leak down test of the weak cylinder with the timing belt on top dead center, to see why the cylinder is low. If you slip the timing belt it usually hurts more than 1 cylinder's valves and the engine would run REALLY bad, and have very low power.
This is not for a person who does not know these engines. Just to set the timing belt on this engine requires a $400-500 tool to hold the cam shafts, there is 1 for the 20 valve engine and 1 for the 12 valve engine. I have replaced both. It would be a good idea to take your Audi to a good German car shop, this is not a job for the drive way so to speak.
To do the timing belt you have to remove the front of the car, like I said I have done a few.
