The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. On A/C compressor replacement, the quantity of oil in the A/C compressor is therefore to be adjusted. Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING .
Different A/C compressors are installed depending on production period and engine.
At the start of production, A/C compressors manufactured by "Denso" type "6 SEU 14C" or "Sanden" type "7 PXE 16/14" were installed. Refer to [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair information).
Depending on the engine, A/C compressors from manufacturers "Sanden" type "11 PXC 14" or "Delphi" type "6 CVC 140" may also be installed at a later time (launch TBD, planned from 09/2012). Refer to [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair information).
Depending on the engine, a different version of "Denso" or "Sanden" A/C compressors may be installed at a later date (introduction not yet finalized).
These A/C compressors are available as replacement parts with different oil fill capacities, therefore note the capacity on the A/C compressor and the exact part number. Refer to the [For engine(s) CTUA, CEUC, CRDB, CGXB, CPNB] System Overview - Refrigerant Circuit (vehicle-specific repair 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 with 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 performance 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.
From 11/2013 the refrigerant oil quantity for the A/C compressor manufacturer "Denso" with the part number "5Q0 xxx xxx" was gradually increased from 80 ccm to 110 ccm. The increased refrigerant oil capacity applies retroactively to all vehicles with this A/C compressor. On vehicles that were built through 11/2012 with this A/C compressor, check whether the refrigerant oil capacity was already topped up during a previous workshop visit. If not, fill the refrigerant circuit with an additional 30 ccm of refrigerant oil. Then note the refrigerant oil capacity with a waterproof marker on the sticker and fill the refrigerant circuit with the above-specified refrigerant quantity. Refer to Commercial Names and Designations (vehicle-specific repair information). Refer to CAPACITIES FOR AUDI A1 (8X_) FROM MY 2011 .
