A/C COMPRESSOR, REMOVING AND INSTALLING, MECHANICALLY-DRIVEN A/C COMPRESSOR, Vehicles with 2.0L Gas: Notes

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Depending on time period of production and on engine, the compressor type may vary. Refer to OVERVIEW - REFRIGERANT CIRCUIT .

At start of production, vehicles without a high voltage system have A/C compressors manufactured by "Denso" (type "6 SEU 14" on vehicles with a 4-Cylinder or 6-Cylinder engine, and type "7 SEU 17" on vehicles with an 8-Cylinder engine). At a later point A/C compressors from other manufacturers can be installed. Refer to REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS (Refrigerant R134a Servicing, Refrigerant R134a Refrigerant Oil and Approved Refrigerant Oil Capacities) refer to parts.

These A/C compressors are available as replacement parts with different oil fill capacities, therefore note capacity on the A/C compressor. Refer to REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS and the exact part number, refer to parts .

Depending on A/C compressor type, different refrigerant oil capacities are designated for the refrigerant circuit. The reason for the different oil capacities in the A/C compressor for an otherwise identical refrigerant circuit lies in the design of the A/C compressor itself, note these oil 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.

If a new mechanically-driven A/C compressor has been installed or new refrigerant oil has been put into these A/C compressors (for example, after flushing refrigerant circuit), the A/C compressor must be turned by hand approximately 10 turns. This ensures that the A/C compressor is not damaged when activated. Refer to A/C SYSTEM, GENERAL INFORMATION (Refrigerant R134a, Servicing; A/C System, General Information).
