I think there is a setting in the heating interface that allows you to always have cool air blowing from the centre vents. I can't say exactly where without going out to my car.
Just got mine back from a/c work. The rear was blowing colder than the front and the passenger was blowing colder than the driver. Ended up being the compressor was going and was sending metal shavings into the system causing it to clog. Dealer replaced compressor, dryer, and condensor and it's as good as new!
Is it both outers, or only the driver side that is warm? Generally, the warm driver side is low refrigerant.
Both outers. I checked and it has plenty of refrigerant.

I did this and it is set to colder, but I want all cold. Do i set these to something else to get that?
Did you actually drain it with a sealed professional system and weigh the refrigerant? (As in, the only way).
Net, from my own experience my money will be on this one that has been dismissed apparently. Been here, done this as it were, and it was the refrigerant after trying a variety of other stuff. Like me, second guy (PaulW--posts more on QW) had the same experience w/ his 2007 S8) last season. The system holds relatively little actually--part of the global warming oriented stuff ultimately--so well under a pound of it means the system is trying to run with 50% or less, and it just can't.
I pulled the solenoid covers and the solenoids. The rear valve was covered in a burnt coolant goo. I cleaned everything and put it back together. The heat works and the ac works; with the valve opening and closing when necessary. I also did an at home coolant flush; not the pressurized stuff, and put in fresh coolant. That was two weeks and 500 miles ago and the car is good!
