Radical idea?
You could buy / borrow a code reader or a Vag.com , carry it in the car and when the light comes on find out what the code is.Then write it down and come back here and ask again.
Or you could change every part on the car while we all make random guesses.
It's possible to purchase code readers for less than $50 nowadays. That's about 20 minutes of your dealers time.

Audi Check Engine Posibilty
Ok, well I went down to my local Advanced Auto Parts and used there computer to check my car, and it said there was 4 different codes or faults with my car.
1) P0441 EVAP Emission Control Setup System.
2) P0432 Main catalyst Below Threshold (Bank 2).
3) P1425 Manracturer Control Auxiliary Emission Controls.
4) P1472 Manfacturer Control Auxiliary Emission Controls.
the last 2 codes had a weird symbol at the end of them like a p on top of a b and yes the last 2 codes said the same exact thing. Now I don't know exactly what these codes mean or what i should do. Is there any way to fix these problems inexpensively?

No. You need to get a real scan with a VAG-COM or dealer to do, because Autozone's scans are often completely wrong.
Do it right the first time, even if it's "more" money, because then you don't have to spend money redoing it a second time.

I second that - getting a VAG-COM is worth the cost - especially if you have a older Audi - or find a friend locally that has one (post in the local forum to see if anyone close has one - if not then it pays to get your own)

Snap On scanner will work with that year.They can go in Generic OBD 2 or have the Euro software and access Audi specifec. So an independant that uses that equipment will be able to trouble shoot it. Sometimes one code/problem will start a dominoe effect. Just have to figure out which code is first in line.If you do not have a independant shop that you frequent, it's time to ask around. Most of the them worked at a dealer as lead techs then branched out on there own.So they are trained by Audi/MB/BMW at there schools then take that knowledge and run with it.Not as expensive as dealer and they give you real answers.
