(1) At the start of production, the compressor types in the first line of the table were supplied with a refrigerant oil quantity of 180 cm . These A/C compressors can be recognized by the part number index (8E0 260 805 with one index or with double index up to "AH"). In model year 2004 (as of approximately 01/2004), a gradual change was made to other types of compressors with a refrigerant oil quantity of 120 cm or 130 cm . These compressors can be recognized from the index of the part number 8E0 260 805 (with a double index as of "AJ") or 4F0 260 805 (and the index "E" for vehicles with 8-cylinder engine). Refer to the Parts Information.
NOTE:

The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. If the A/C compressor is being replaced, the quantity of oil in the A/C compressor must be adjusted. Refer to Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING .

The Audi A4 is equipped with different A/C compressors depending on engine and production period. This A/C compressor is available as a replacement part with different oil capacities, therefore note the exact part number. Refer to the Refrigerant Circuit (vehicle-specific service information) and the Parts Information.

The reason for the different oil capacities inside the A/C compressor is due to the design of the A/C compressor (with or without an oil separator on the high pressure connection) or to the design of the refrigerant circuit if the A/C compressors are have the identical design. Pay attention to the different capacities. Too much oil in the circuit leads to higher pressures and reduces cooling output of the system. Too little oil may lead to lubrication problems in the compressor.

A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
