Hello Folks, Looking for some help with diagnosis of AC problem on my 2012 A4 S-line. I am trying to find reference material or some sort of troubleshooting info as it relates to the AC system on this A4. I have a good bit of experience with automotive AC systems but I am not familiar with the Audi Automatic systems. The problem is not a simple refrigerant related problem as I can tell. I need to know things such as what specific components are in the system and controls, wiring and such to diagnosis this problem. Any help with pointing me toward manuals or online references will be appreciated.
