    Hi all

    On the A3T's climate controle you can use some factory codes to get some info on your car. Is there any one that knows what the code is for charge air temp ?.

    From what is posted elsewhere on the forum, the cc can tell you what the settings are etc, but you need VAG com to change them.

    Press and hold the recirculation button. Then press the manual flow control up arrow. You should see a 1c. Press the temperature up ("+") or down ("-") buttons to select a code number. Then press the recirculation button again. The value should display. Press the temperature up or down button again to display another code.

    NOTE: Air Flow Motor (V 71) and Potentiometer (G 113) are not installed in USA/Canada vehicles. Disregard values displayed for these components.

    I've only used C17 - speed in km/h. Does anyone know if this can be changed to mph?
