Engine, Starting With Empty Refrigerant Circuit When Necessary
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2022 Audi S5 Sportback, 2022 Audi RS 5 Sportback, 2022 Audi A5 Sportback, 2021 Audi S5 Sportback, and 2021 Audi RS 5 Sportback. However, it is still accessible from the selected car via links, so may be relevant.
If it is necessary to start the engine on a vehicle with an A/C compressor without a A/C Clutch -N25- with an empty refrigerant circuit.
- The refrigerant circuit must be fully assembled.
- There must be no vacuum in the refrigerant circuit.
- If the A/C compressor was removed: At least a quarter of the prescribed refrigerant oil amount must be in the A/C compressor.
- Engine speed must not exceed 2500 rpm.
- The engine should not be run for longer than absolutely necessary (for example, to move the vehicle into the workshop area).
If only the refrigerant was evacuated (the A/C compressor was not removed), it is guaranteed that there is enough refrigerant oil in the A/C compressor to continue lubricating the A/C compressor for a short operating period due to the design of the refrigerant circuit.
