Default How good is the AC?

On the GSW? We had some warm weather last week, about 75 degrees. Driving on the interstate with the windows up and the sun shining the cabin got pretty warm so I ran the AC for about an hour. It was OK but didn't seem icy cold like I thought it would be. Cool enough at 75 degrees F but I am wondering how it will be when we get to summer temps of 100 plus here in the desert. I do realize that it is a temperature differential and I will stick a thermometer in the center vent for my next test to see where I am at with that.

Normally I buy white cars with light interiors but the black interior on this car looks really great so I bought it anyway. The outside is white and I plan to get tint before summer.

In a word: very.
Even driving in temps pushing 35-38C, I've never had complaint about the A/C in my mk7.

There is a technical service bulletin out on the AC compressor solenoid valve.

My dealer changed out the entire system under warranty because they get to charge VW more money than just changing the valve.

Blows cold now. But not cold like my wife's Honda.

hot country will change your world!

IMO in normal coding mode, at idle the AC duty cycle is something like 25-50% it'll be coolish but not cold. its not until rpms are constant and above 1,500 that ac duty cycle is increased.

Once coded the AC will blow a solid 38F no matter what the engine is doing. At least this is my experience with manual HVAC system on our Alltrack.

South Florida guy here. I've noticed around town the car is not as cool as other cars I've owned. But once on the highway and doing 70mph it drops the temperature and definitely feels pretty damn cold. May have to read up on that hot country code for when the Florida Summer is in full effect.

Central Florida guy here.

I don't feel my A/C gets too cold during the summer. I always have to run it on Max on a higher fan setting than I would prefer. (Last summer was my first in the GSW)

I was able to set it to Hot Countries last month and hadn't had much of a chance to notice any difference as it's been cool here. Last Thursday I drove the 90 miles to the stealership for an oil change and had it running for 45 mins on Max fan droning away and it was only barely cool enough.

Even checked to make sure my settings had been saved correctly the next day. Still set to Hot Countries. I was considering breaking out my A/C gauges and adding some refrigerant, but you can bet I'll check the A/C thread next instead.

Edit: I have 20% tint all the way around and a 10% strip at the top of the windshield.

Thanks and cheers!

No need to break out the A/C gauges, read what VCDS is requesting and what the demand is.

RCV are still a thing on these cars and easy to replace (yet a dealer will toss a new compressor in as their only solution under warranty or not)

This has been my experience, too. Our VW A/C's ('98, '12, '15, and '16 eGolf) have all been adequate but not even close to comparable to the asian imports my wife's parents own.

Mines pretty weak even after replacing the return control valve. Wow did you really drive 90 miles for an oil change???

When I was shopping for mine, I noticed a number of 2015 Golfs had recharged ACs listed on their Carfax.

Being of the impression that a recharge = leak, I called a couple VW specialists to arrange PPI’s and they assured me it was normal with MK7’s due to use of new environmentally friendly refrigerant and the system only holding ~1lb of it.

Mine is ice cold, but I also recently learned that mine was a “Hot Country” model sold in Florida.

I had my rear coil spring recall done today and I asked about the VCDS hot climate adjustment.....neither the service manager or the tech had ever heard of it....the service manager went so far as to say if there even was such a thing, it would cause the system to freeze up.
Until I get set up with my own VCDS I'll ask the local VW indy to check it for me.
