The receiver/dryer may be attached to or integrated in the condenser on the Audi A1 / S1, depending on the version of the condenser. A dryer cartridge is installed in the integrated receiver/dryer and can be replaced separately. An attached receiver/dryer (introduction TBD) must be replaced after the flushing. Refer to the Parts Information and Refrigerant Circuit (vehicle-specific service information).
There are different versions of the A/C unit (different heater core and sears different expansion valve etc.) depending on time period of production and from the VIN number on Audi A1 / S1. Refer to the Parts Information. Vehicles with the type keys "8X1" and "8XA" in the VIN have an expansion valve installed, where both refrigerant lines are attached at the top. This is where the Refrigerant Circuits Adapter Set 1 - Adapter 34:VAS 6338/34 fits. For vehicles with the model codes "8XF" and "8XK" in the VIN number, an expansion valve is installed, on which both refrigerant pipes are attached at the bottom.
