just glad I could help out......
And as far as wheel bearings go, if you don't have a HubShark/HubTamer/other bearing tool at your disposal, I'd recommend having someone else do it.
Flat rate time for bearing: 2.2 hours
Time to do bearing with Hubshark: 50 minutes
do-it-yourselfer in driveway time: 5-6 hours
Take care...and feel free to post any other vag-com questions :-)

**UPDATE** Bracketracer, it was the catalyst
Took it into the dealer and they confirmed the catalyst tested bad.
They had to reflash my ECM first per a TSB dated 12/19/2006. The TSB number is 24 06 06 -or- 2013801/1....I'm not sure which refers to the TSB number.
Even though I have a MY '02 (late '02 build date), I had the referenced ECM (J220) software version indicated in the TSB.
They had to reflash the ECM and run the diagnoses again to confirm the cat was bad. If the diagnoses came back OK after the reflash, I would have been out $115 and tax for the reflash. Seems crazy to me that I was on the line for the reflash $$, but I really had no choice. Since the cat still tested as bad, I did not have to pay anything.
As to the wheel bearing, it is in an Indy shop right now getting looked at, and most likely replaced. As much as I would have enjoyed replacing a bearing myself, I already determined that I needed someone else to do it as I have no press to remove/replace the bearing in the housing. They quoted $275/wheel for a bearing, $325/wheel for bearing and housing which seemed fair to me, considering my dealer charges $125/hr for service work with 3 hr book time on that job.
btw....is that your shop referenced in your email address? I'm curious what your mailing address is. I want to snail-mail something to you if you're OK with it.
Thanks again for your VAG-COM help, it saved me some money.
