Hello. Out of nowhere our 2021 id4 allows us to turn on ac as normal but no cool air is felt. Tried restarting infotainment. Would love this to an easy at home fix but perhaps we need to see the dealer? Is there a known issue? Thanks!
ID.4 Air Conditioning issue

9/22/22 update:
Audi part is not approved. Obviously Amazon replacement part voids VW warranty. Below is latest invoice.
Last night low was 49 F, today's high 67 F. I opened the sunshade for the first time since April.
Current status: no AC. Next visit to dealership is when part shows up.
To be continued...

That's funny (or sad) that they claim they won't cover the Audi 'part'. They have the exact same part number.

I think they don't have a way to charge it back to VWoA under the warranty.
🤷♂️
The Audi part may be unavailable as well.

Might be that everyone figured out the Audi network had them in stock and bought them all up as well.

I first posted Aug 24th. Today, Sept 29th the A/C was fixed. I complained to VW customer service last week who followed up with one of the two dealers I took the car to. After previously telling me that the part was unavailable in the US, the dealer called me a couple of days later. They had obtained the part from another dealer. The next day I received a call from the first dealer who also obtained the part. I took the car in 4 days ago for replacement of the A/C sensor. The part # is 4 M0-959-603-E Sensor. Note that it is a different part number from some listed by others above. In removing the old sensor the technician stripped the threads of the refrigerant line the sensor attaches to. That required them to order a new refrigerant line (1EA-816-743-J CoolantPIP). The car, which was previously drivable, was now undriveable and sitting at the dealer for 4 days.. Thankfully they received the part today and I just picked up the car and it appears everything is working. Hope this helps others.

And yet it's also still an Audi part as well. 2020 Audi Sensor. Pressure. Refrigerant. Air. Conditioning - 4M0959603E - Genuine Audi Part (audiusa.com)
Not that that helps.

SitRep 10/27/2022 late entry:
Part finally came in I delayed repair to coincide with 20k service 19,757 mi.
Dealership forgot to reset service reminder 😖, had to return for 20 min the next day.
Waited two weeks for a warmish day to test.
Resolved.
First "major" (at least from my wife's pre-menopausal point of view Lol) issue with our 2023 and 4k miles. AC isn't blowing out cold air. We tried ever setting possible (I think) and no cold air. Appt scheduled for next month, no loaners!?! So from his Thread, it looks like a bad sensor, but there are many various part numbers???
AC on our 2023 ID4 Pro (2,300 miles) did not work for 1st use about 2 weeks ago. Took to the dealer and it had no refrigerant, obviously a leak but the dealer could not find it. They charged the system and put a dye in it, told us to use it and if it fails again to bring it back. After 2-3 days of use it stopped blowing cold, assume it leaked the refrigerant again. Will be taking back to dealer next week.
I literally just got ours back, and they did the same...no refrigerant (they blamed the factory, yeah okay) and the dye test indicated no leak. Now I'm bummed to hear that yours wasn't fix as both our 2023 appear to have identical issues. Please keep me posted on the next "remedy." I'll let my wife know to enjoy the cool air for the next couple of days SMH
Just used my AC for the first time a couple days ago. It was making a squealing noise and not blowing through the vents. Discovered that all the dash vents were turned off and that the slider on the vents turns them on and off instead of moving the air stream left and right as in a normal car. 
Once the vents were turned on it worked great and of course the squeal went away because the air now had someplace to go...

Upper 80's this week and my wife would not be pleased without air conditioning, so the loaner has working A/C
The AC stopped blowing cold air on our 2021 ID.4 with ~9k miles. Took it to the shop. The car was throwing the U032A00 code. The fix was to reprogram the AC control module.
There is a VW Technical Tip (not a TSB) for this issue: 87-23-02TT.

Yes and you should have the proper recover/vacuum/recharge equipment. This would probably violate your warranty.
