Oil Distribution
WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. 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 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 before switching off and the ambient temperatures, 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. Therefore, observe the notes for replacing the refrigerant circuit components. Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING .
