Oil Distribution

WARNING: This page is about a different car, the 2022 Volkswagen ID.4 and 2021 Volkswagen ID.4. However, it is still accessible from the selected car via links, so may be relevant.

When the A/C system is being used, the refrigerant oil that was in the A/C Compressor -VX81- before switching on the A/C system for the first time is distributed throughout the entire refrigerant circuit.
Depending on the previous operating condition of the A/C system when switching it off, the ambient temperatures, etc., the distribution of the refrigerant oil in the refrigerant circuit varies.
A general statement about the refrigerant oil distribution in the refrigerant circuit is therefore not possible.
Pay attention to the replacement information for refrigerant circuit components. Refer to COMPONENTS, REPLACING (R744) or COMPONENTS, REPLACING (R1234YF) .
