WARNING: This page is about a different car, the 2023 Volkswagen Arteon. However, it is still accessible from the selected car via links, so may be relevant.

Required adapters for the connections to A/C compressor	Adapters necessary for the connections to the reservoir or receiver/dryer	Miscellaneous
Refrigerant Circuit, Cleaning: Low pressure side: Refrigerant Circuits Adapter Set 1 - Adapter 12:VAS 6338/12 connected to the A/C Service Station and the Refrigerant Circuit Adapter Set - Adapter:VAS 6338/48 High pressure side: Rinsing Adapter:VAS 6338/3A	Receiver/Dryer:-- Bridge the disassembled refrigerant lines at the receiver/dryer using a desiccant bag. Refrigerant Circuits Adapter Set 1 - Adapter 6:VAS 6338/6 or Adapter:VAS 6338/8 depending on the manufacturer, quantity: 2 Hose:VAS 6338/31 -- Install a new receiver/dryer (dryer) after flushing.	No expansion valve is installed in vehicles with a heat pump. -- The expansion valves Refrigerant Expansion Valve 1 - N636-, Refrigerant Expansion Valve 2 -N637- and Refrigerant Expansion Valve 3 -N638- must not be removed or replaced.-- Using the Vehicle Diagnostic Tester start the "Refrigerant circuit, charging" function in the "Basic setting". Doing so opens the electric valves on the refrigerant circuit. The function is active and can only be ended when the refrigerant circuit has been flushed. Keep the Vehicle Diagnostic Tester connected so that the valves stay open.
