I changed my AC to Hot country. Much improved performance, especially with my non-tinted, black interior, GSW

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.
