WARNING: This page is about a different car, the 2023 Audi S3, 2023 Audi RS 3, 2023 Audi A3 Quattro, and 2023 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.
- Only valves and connections that are resistant to refrigerant R134a and refrigerant oil must be installed.
- There are different connections (outer diameter) for the high pressure and low pressure sides.
- Discharge the refrigerant circuit before removing valves or valve inserts.

Allocation in the vehicle. Refer to Refrigerant Circuit (vehicle-specific repair information).
WARNING:
There is a risk of freezing.
