Only a Vag-Com tool will be able to help you...
you need to find one in your area and get this checked. CEL lights come on for a reason (most often, at least) and are there to help you to protect your engine.
The person that will be able to help you will have a Vag-Com tool - be it a dealer or an enthusiast, and will be able to tell you the reason for the light. Then you'll need to fix the problem itself. It could be a blown DV, a bad MAF, or any number of other things... important stuff.
Without a VAG-Com, I'd hit the dealer asap. Just my $0.02.

The computer you had your car connected to was most likely a VAG-Com tool...
If that didn't work go to the dealer.
Dood, you have a $30k car - take the opportunity to service it properly and maybe it'll be around awhile.
jeesh!

so that means that it is possible that the dealer I bought it from can have that equipment and not just an AUDI dealer? If so then wouldn't it have told him the area of the trouble from the memory?
It did not locate a specific area.

OK...
Here's the skinny -
A VAG-Com tool is available to non-audi dealers and the general public. A number of companies sell this tool and the best known version is sold by: www.ross-tech.com
When a dealer connects your car to a computer he is most likely (although I have seen my dealer use a Ross-Tech version for some problems), using the much more expensive Audi/VW system which costs about $15,000.
When the CEL light comes on it will throw a code onto a part of the ECU that collects data. This code is the rationale for the light being on and can then be traced to a specific issue and consequently fixed.
If your non-audi mechanic used a VAG-Com tool, he most likely did not use the $15k version and isn't a Audi Technician either. You need to get the facts from a qualified technician or you need to learn to live with the CEL coming on and off as you have indicated it does. Perhaps the issue is one that the Ross-tech software doesn't support (?). According to you, for $75 bones, authorized service dept. will diagnose the problem. At that point you get to decide whether or not to fix it.
I know what I would do...

The dealer should make it right but they sometimes don't give a sh*t...
about you after they made the sale.Are you still under warranty or have an extended. If so you have to keep going back even though it's a PIA!
