I found someone local with a VAG-COM who checked the stored codes. I'm not sure of the number (possibly 445) but the text read something to the effect of; 'A/C shut off due to refrigerant loss.' Additionally, per the TSB in Depiry's post #7; MVB 13, field 1 displayed a value of 12.
I'm going to take it to the dealer tomorrow with fingers crossed in hopes that they fix it under warranty. I think I heard somewhere or read in this forum that dealers won't recharge an A/C system as a warranty item. Has anyone else experienced this?

I'm happy to say the dealer recharged the refrigerant and added a dye to check for leaks. I think it's odd that a 4yr old car would lose refrigerant so quickly, and it was appropriate that it was covered under warranty.
Hopefully any leaks will show up with the dye. The dealer told me to return in a couple of weeks for them to look it over with a UV light.
We're just happy we have A/C now. It's been warm enough the last week to need it.

I appreciate the info.. It's the dealer's problem as far as I'm concerned. They put the dye in it, so if it creates issues later they're on the hook for fixing it.

Just for general information, dyes are a wonderful tool to pinpoint where leaks are when a simple soap water or other tool doesn't work. However once the leak is found and sealed should a vacuum need to be pulled by doing so you're not only getting rid of whatever 134 is in there but also the dye you just injected. This clogs up the extractor, pump and gaskets which is why many shops will not do it. It's also hard to hide as you've got this purple dye visibly showing...

Does the dye not have a similar effect on the vehicle's compressor, gaskets or seals?

Both the sealant and dye inject foreign chemicals into the system. When you draw a vacuum, you pressure suck all air and loose particulates out of the system in addition to the refrigerant. So yes it's a catch 22 but it's the best of a bad situation. The alternative is to replace the faulty part normally upwards of 2 grand. Since A/C shops invest thousands into their tools they obvioulsy don't want their tools crapped out and would prefer to reinstall a compressor, evap etc and do a purge on a clean system that on one full of .... .
Since the dealer is going to cover this, it's a non issue for now. Since he won't replace the entire system the next person who does it will inherit it...

The dye is not the problem, it's the sealant. Use the dye, find the leak, repair it. Pull a vacuum, and recharge. Avoid the sealant.

I neglected to mention that the dealer didn't give me a copy of the service invoice at the time of the repair. They mailed a copy. Now that I have it in hand I see that they replaced a leaking o-ring at the compressor. They also noted that I should drive it for a couple of weeks, then return for them to check for signs of leaking dye. Hopefully the bad o-ring at the compressor was the only leak and we're all set for a while.

Chris consider yourself very lucky. My wife's 300M just out of warranty had a leaky O ring and it was only through sheer perseverance (oh surprise) that I found the O ring in San Antonio (whilst in Hawaii) after 5 days of trying. No one would sell me just the O ring. They wanted me to throw out a perfectly good compressor for a 18 dollar part plus 35 bucks to ship it FedEx. The compressor for the 300M was made by Toyota btw,
The week after I installed that, the Evap went and I swore I will never go through that again. Sixteen hours to get to the *&&^%^&^&**(*&^% evap.
Air bag, steering colum, the entire dash ripped out to the bulkhead...
But guess what? My heater core died on me on my Durango last winter and went thorugh the same pain to get to that. But that's it!
So consider yourself lucky that it was just the O ring and they didn't charge you for a new compressor. My advice is get the part number for the O ring and buy a spare....

Ugh. Heater cores suck. I imagine there's a good reason they don't put them in a more easily accessible place.
Replacing the compressor would have been a warranty repair anyway, but I'll take that advice and find the part number for a future spare... Thanks.

Per siberian's suggestion, for posterity; The part number according to the dealer's service advisor is 8E0260749. <-Those are two zero's, not O's.
edit; BTW- I forgot to mention I returned to the dealer last week. They checked the system again and found no evidence of leaking dye. Looks like the O-ring at the compressor was the culprit.
