Thumbnail Filmstrip of Audi A/C Pressure Switch Schrader Valve (Upper) Images
This schrader valve is located where the A/C pressure switch is installed to allow the switch to read A/C system pressure without losing refrigerant if the switch is removed. This schrader valve is a common source of small refrigerant leaks and can go unnoticed since it is under the pressure switch. An easy way to check for a leak is to remove the A/C pressure switch and inspect around the schrader valve for signs of leaking refrigerant, which will look like a white sprayed substance.
