Volkswagen Polo Service & Repair Manual: Leaks or Internal Damage, for Example Noises or No Output

  Note
For vehicles with an electrically-driven A/C compressor, de-energize the high voltage system before removing the A/C compressor. Refer to → Electrical System Hybrid; Rep. Gr.93.
–  Discharge the refrigerant circuit.
–  Remove the A/C compressor.
  Note
In the case of internal damage (on A/C compressor), flush refrigerant circuit with refrigerant R134a. Refer to → Chapter „Refrigerant Circuit, Flushing (Cleaning) with Refrigerant R134a“.
If a different A/C compressor is installed with a different refrigerant oil, the refrigerant circuit is to be flushed with refrigerant R134a. Refer to → Chapter „Refrigerant Circuit, Flushing (Cleaning) with Refrigerant R134a“.
