VCDS is an invaluable tool for these cars, get one, even if its a cheapy ebay one, just so you can check for faults etc.
I presume by "York, PA" your in the US? This is primarily a UK forum, and there are slight differences between the models. Your car will most likely have electronic throttle, whereas UK 1.8T quattros are all cable throttle. Thats a good thing though as it means you have a wider range of diagnostics available to you.
