Charging Refrigerant
NOTE:
- When charging the high-pressure side of refrigerant circuits, always use maximum amount of refrigerant (some of the refrigerant remains in the charging hoses).
- The specified capacities for refrigerant R134a apply if no other different specifications given for the S and RS.
- Make sure theA/C service station is standing at the same level as the vehicle (maximum difference: 50 cm) when charging the refrigerant circuit. If a difference in height is large enough, a difference between the amount of refrigerant displayed on the service station and amount actually filled in the circuit will result (depending on the version of the A/C service station). The ability of the A/C Service Station to perform an exact filling can change.
- For compressor allocation (Zexel / Valeo, Sanden or Denso / Nippondenso) refer to [For engine(s) BPY, CETA, CCTA, CDMA, CEPB] Removal and Installation (vehicle-specific repair information).
- Refrigerant circuits converted from R12 to R134a are to be filled with the quantity indicated in the repair information "Air conditioner with refrigerant R12". Refer to Air conditioner with refrigerant R12. (This repair information is only available in hard copy from Audi).
- Beginning the production year 2006, the name of the Zexel A/C compressor was changed from Zexel to Valeo.
