WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
This control module switches on and off the A/C clutch and therefore the A/C compressor. It turns on the radiator fan and calculates the refrigerant circuit pressure in vehicles with a High Pressure Sensor -G65-. Refer to appropriate SYSTEM WIRING DIAGRAM and COOLANT FAN, REMOVING AND INSTALLING (vehicle-specific repair information).
