I think I'm just looking for confirmation on the compressor being dead from looking at the measuring blocks here. The first is with ECON on... group two is showing 6.0 and the second is with ECON off, and it's showing a 0.0. System was emptied and refilled in 2018 so unless I have a leak I think it's a little soon to be low. No Auto HVAC / module 08 codes at all. Both fans working as they should. If it's the compressor, is there anything else I should get to while I'm there besides the drier and the orifice up top?
My 2006 W12 leaks out every approx. 5 or 6 years. Not worth the time to find what must ultimately be a tiny leak. Was just refilled by brother in law in last month for probably 3rd, maybe 4th time. Back on the job blowing nice and cold again.
System only holds just over 600g of refrigerant. That is only half or so what a system did a few decades earlier. From the one time dealer gave me the measurements pre- and post work, by time it was down half (to about 300g) it pretty much no longer worked.
Net, for the dollars, go get it recharged. The correct way with the shop standard machine--empty it and weigh amount added. The DIY can stuff alternative without measuring is your much more likely path to then actually need to diagnose the compressor if/when it blows.

I was hesitant to try this first because I thought that the compressor needed to be able to run in order for the system to take the refrigerant. Is this not the case?

If you are thinking 60's-80's/old style A/C with a clutch that clicks on and off, that is not the Audi set up for a long lime. There is no clutch to engage or disengage it--a variable displacement compressor IIRC. If the fan or serp belt is turning, the compressor is capable of working and probably rarely actually failed internally. Even on the clutch type (or these), if system was opened, you typically get in as much as you can using the can or recharge system pressure on the "low" (pressure) side, and then compressor does its thing to allow suction to draw in more and reach intended refrigerant capacity.

Whoa whoa whoa, some terrible advice being given here, sorry!
Do not try and diy fill it with a can of EZ FREEZ or whatever from your local parts store. That’s a one way street to overfilling it and hydrolocking the compressor and $$$$ to repair.
This is an oft overlooked nuance with “always on” variable displacement AC compressors that has led to lots of expensive mistakes. Just folk don’t realize that they wrecked the compressor by overfilling it and just think that because the AC still doesn’t work after a diy fill is because the compressor was already blown. If they’d only filled it using the proper equipment, they wouldn’t be down an AC compressor and a whole bunch of other AC system parts that are now full of swarf from the blown compressor.
The only safe way to do it is to have it done properly by a shop with an AC charging machine.
You have been warned. Up to you how lucky you’re feeling.

Frankly, please read back to my first reply when I tried ot help guy out a week+ ago . 'Way, way, way' too fast on the trigger to blast someone. Happens when you come in mid stream and don't read back to understand context.

Well, aside from I can't really even read whatever you tried to quote...,
Rather than deflect, how about start with a novel thought: admit you pretty obviously did not read whole thread carefully. Classic fire, ready, aim. You went right past that.
Guessing at what you are trying to refer to, in context I think response made sense. Also not aware in that once a warning is issued--in the very first reply from the same guy and to the other very same guy--we are supposed to repeat it all again. Hmmm, ... x 3. FWIW, later on, I took it the guy was asking perhaps a more general question about recharging I took as generic or from other car experience. Maybe not D3 specific in particular. Also why--well before your last reply--I had already gone into the variable compressor and how it's different than old clutch driven ones. That should itself have been a clue back to you too...if you were taking time to read it. Since I have posted the warning in dozens of other threads, yeah I know it...just like I did here for folks who bother to read it.
Gets old answering questions and trying to help by the way on almost two decade old cars. Then you come in and take full on, way off base pot shot in your opening line, a week late. And now BTW, the interrogation back of my intent and meaning as you try to defend. Huh x 3. Not cool either.

Word salad? From a guy who can't use AW's text tools (other than curiously the face stuff?), leaves a literally unreadable post we have to guess at, and who obviously didn't timely read the thread to start with but can't bear to admit it? More bob and weave instead. Not what I expect of AW veterans. You do have strong knowledge and good posts often, but the 'tude here was unnecessary and just not right.
