Oil Distribution

When the A/C system is being used, the refrigerant oil that was in the A/C compressor 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.
Note the information about replacing refrigerant circuit components. Refer to the appropriate Service Information .
