HELP finding Heater Control Valve!! its FREEZING!!!!
I have a 03 Audi A4 3.0 Quattro. A couple weeks ago the heater stopped working. I finally came to the solution that the heater control valve is stuck on freezing cold! The problem is, I cant find that mug anywhere! Ive searched for hours to try to find a diagram that displays where the heater control valve is on my model. Could anyone please post a picture of where it is??

First of all, you are in the wrong A4 forum, you want to post this in the A4(B6) forum.
There isn't a control valve for the heater, the water is flowing though the heater core at all times. There are mutiple doors with actuator motors in the Air Distribution Chamber that regulate the temperature, along with a computer controller, temp sensors, that all relates to your problem. You need to scan with a VAG-COM (not a generic OBD2 scanner) to see if there are any codes and, if there are, it will tell you what doors(flaps, etc. need looking at.
This is where a 2003 can become expensive.......
