It's been over 90 here the last 2 days, mine is blowing ice cold, also my widows are tinted so that helps a bit having the wagon.. No complaints
Also everyone is "tweaking" the last drop of any improvement(s) - or compromises to get up to the next higher MPG on the MONRONEY.I think so also. Could that be because of the new refrigerants?
Good idea. Prior to reading your post, I was going to suggest attempting VCDS tweak of trying the VCDS tow setting as per the post: http://forums.tdiclub.com/showthread.php?t=478382 It is understood that that energizes the radiator fan more which gets air moving across the condenser. The Hot Temp countries probably does the much the same.There has been plenty of discussion about inconsistent AC systems over at vwvortex. If you have a VCDS you can check to see if you have "Hot Country" enabled. It seems like there are some cars sold that had it enabled and others that didnt. Reading through the thread below, people have reported getting cold air much faster after making the VCDS tweak.

Instructions from the link above:
1) Open VCDS
2) Go To Select Modules
3) Under the "Installed Modules" window - select number 08 - Auto HVAC
4) After the control loads - select Coding - 07
5) Click the button for "Long Coding Helper"
6) Press Tab or arrow down key until you see "Byte 12" selected
7)Under the drop-down for "Bit 4-7" select "10 Temperature Adjustment: Cold (Hot Countires)"
8) In the top-left corner of the window - select the "Exit" menu item
9) Press the "Do It" button to save the new setting
10) If all goes well - you should see a popup "Coding Accepted"
I haven't done this myself or checked what my setting is since I am happy with how my AC performs. Might check just to see what my settings are just for kicks.
Thanks for the info. Just checked both of my Washington DC area-purchased Mk7's and both were set to "00 Temperature Adjustment: Normal". I set both to "10 Temperature Adjustment: Cold (Hot Countries)" and will see how it goes. I rarely use A/C outside of June-August, so when I do use it, it is in a "hot country" situation.There has been plenty of discussion about inconsistent AC systems over at vwvortex.

I think I saw on the news that you are pretty hot there right now! I am hoping that this will be a solution. If it is, that would answer why there are so many different opinions on how well the A/C's on these cars are performing.Thanks for the info.

Many modern air conditioning systems (including VWs with Climatronic) will reduce compressor load in most situations when the temperature setpoint is satisfied.Wow, 32 degrees!! I remember my sister's 78 honda civic would freeze up (literally a block of ice) if you set the compressor too cold! I liked that you could could actually adjust the compressor on those cars rather than now where the compressor cycles don't change and you have to introduce HEATED air if you are too cold. Seems wasteful. I end up doing what the previous poster said, turning the a/c on and off if it is too cold
I know this image is tiny, but for some reason I can only get it to show as a thumbnail.
What it shows is the temp in the vents of IBW while sitting in an 85 degree shop with the A/C on full. Air coming from the vents was about 36 degrees. After a little more tweaking Chill got it to 32 degrees.
Not sure you're talking about the same thing, Bob, but if so this is about a 50 degree drop compared to the temp in the car, which wasn't moving, engine was idling, and it never had a chance to cool down inside. Not sure if the GSW would be able to do something similar. I drove the car around this morning and it was 90 and sunny out. I kept the fan on 1 and had the vents pointed away from my face.
Thanks. I never owned any Climatronic cars. I would like it if they all muted the compressor that way.Many modern air conditioning systems (including VWs with Climatronic) will reduce compressor load in most situations when the temperature setpoint is satisfied.

40 or low 40s sounds good to me. I think that Dad said his car put out air just under 50 with outside temps in the 80s. I will see what readings he gets in the next few days assuming the dealership returns his car today.never saw temps under 40 degrees with a prob in the center vents.
Your symptoms sound identical to what I described above as the same RCV problem VW has been plagued with for years.My brand new (old) 2015 GSW has an AC issue. On my 30 minute commute home today it didn't come on until I turned it off and turned it on in my driveway. It has a major delay if it ever decides to come on. Plus it seems pretty weak when it is on. Taking it back to the Dealership next Wednesday. This sucks because I was planning my first major road trip, with my son, in the car to Cincinnati this weekend and now I think I"m staying home. Thanks VW. Your AC sucks. :-(.

Part I do not understand is: We do not run the A/C for 5-7 months at a time. But nothing (generally) go bad for years.
Yes.That's why I use A/C at least once every couple of weeks in the winter, usually in the form of defrosting the windshield. Keep that compressor lubed up and exercised!
Saw something similar with my Gen4 4Runner. It was a best practice to engage 4Hi and 4Lo once a month or so as some people who went a year or more would get a stuck actuator and couldn't engage 4wd.
