I'm not sure if VW is still using the variable displacement air conditioning compressor that they've been using for the past ten years, but if so, the problem could be the refrigerant control valve sticking. That has been a common and ongoing issue for a while now and it's possible that it has carried forward into the 2015 model year.

Currantly weighing the cost vs night vision results with a tint job. If not good at night, would have to srape it off --

My wife's RAV4 is perfect, but I do not drive it. So there is no direct comparison.
They say you can put a light shade of tint on that will still block the UV and IR rays of the sun. My wife wants dark anyway despite my concerns. It might work for you though.

I am looking at Sun-Tek cpx tint. It is supposed to last longer and they say that even the lighter tints block a lot of sun. I just got a squamous cell diagnosis on my lip so I might put some of this lighter stuff on my Passat.

My GSW has been sitting 2 years - I've had it 4 weeks with about 1,000 miles so far. I'm bringing it in for 1,000 mile check up next weekend and will ask them to check refrigerant level.
My empathy for you guys.

Beginning to believe the "2 year" storage is going to affect more than a few units.

Let us know what happens

This would explain why some people have issues and others don't. I've only used the A/C in my '15 once, but it seemed to work fine. I wonder if some refrigerant lubricant would help.

In reading this thread, I find that it is rather subjective: "Weak", "Feels", etc. and different climate/humidity conditions. Previously, mine "felt" "fine".

In an attempt to quantify, I went out and started my '15, it had been sitting in the shade for a couple days, using a Ratek surface reading probe, outside car temp. surface, black dash surface & interior seat surface all had readings of 86F to 87F. Engine started, engine at idle, AC then turned on ,external air source (not recirculating), fan on high, outlets in vent only position, w/ all vents open, the reading inside the center duct as viewed read through the open vent:
- The initial out coming air temp was 86F (consistent with the air in the system.
- The temp started decreasing quickly, within a minute, out coming air was in the low 60'ds F.
- In under 2 minutes the duct/outcoming air temp was 55F.
- I then rechecked the dash surface & seat surface, they decreased to 1 deg to 85/86F. The interior had cooled 1F.

It strikes me that -30 F temp differential with the system running at idle in less than 2 min is pretty darn good! I was amazed that it was that much. Now I know why it "felt fine".

VeeDub & IBW may be on to something.

Nice observation(s)

Wow Bob, that is what I like about this forum. Lots of serious thinkers.

It would help to know just what the temperature coming out of the vents is supposed to be according to the design of the car. I'm not sure that 55 degrees is cold as it should be.

I was thinking also that our information (aside from yours) is subjective. One person's comfort is another persons torture.

Bob, although those sound like good results, MKIV cars do better. I just picked up my wagon after having the expansion valve, receiver/drier, and compressor replaced, as it wasn't blowing air as cold as I have come to expect. With the fan on high and the A/C on recirc (I think), Mr. Chill (see what I did there) saw 32 degrees F at the vents. MKIV cars with good A/C will fog the windows on a hot day.

Typically, it is the temperature differential of the air being cooled. Temp of ingoing air vs outgoing air. i.e., how much is the air being cooler that passed over the evaporator? To me 30 deg drop is better than I expected.

That said, I am impressed by Peter's MKIV drop above, I would expect nothing less then perfection from Mr. Chill (Pun intended).

I will recheck with the air set in the in recirculation mode.

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 will agree with someone elses statement that the AC is definitely weaker at idle. I was sitting in traffic one day with the fan on 4, windows up, lowest temp & i have 22% tint. Felt like the vents were blowing out luke warm air. Started moving then i could feel the temp drop.

Not surprised as it seems like a design "feature" with the one cooling fan, high idle in hot temps with ac on etc.

I chop it up to newer cars just having a generally "weaker" feeling ac than old ones. Drove my car to vegas and back last week. Was 105+ a couple days and i never had to max out my fan speed in the car.

TL;DR AC feel is super subjective & performance is based on many things.

not the strongest A/C I've ever had, but gets the job done......My wife has a Subaru XV, seems a lot of new cars do not have ultra powerful A/C's these days....just a generalization.

Put me squarely in the underwhelmed camp with the AC on my new GSW. I have put almost 4000 miles on mine since I purchased and havent been too impressed with the ability of the AC to cool off the car quickly, although I do not like to turn the fan up over speed 3 or so, my mk4s never had this issue and I almost never turn the fan over setting 2 on those (no foam coming out of the vents and I think this helps FWIW)

My car seems to be one that was used more than most during its 2 year hiatus, as it had just over 1000 miles on it at pickup so it didn't sit as much as some of the others that I have read about.

Perhaps Ill get one of those vent termometers and see what is actually outputting. (any suggestions on what to use?)

My "new" 15 Golf is not as cold as my 11 was. I think I'm going to throw my gauges on it when I get home later and see if it needs a little 134

I think so also. Could that be because of the new refrigerants?
