Electrically-Driven A/C Compressor
- With A/C Compressor Control Module -J842- and Electrical A/C Compressor -V470-
- Removing A/C Compressor from bracket and re-installing in vehicles with 4 cylinder. Engine. Refer to ELECTRICALLY-DRIVEN A/C COMPRESSOR, REMOVING AND INSTALLING AT BRACKET (AUDI A6 HYBRID) .
  NOTE:
  Depending on the time period of production and the engine, the compressor construction type may vary.
  
  The A/C compressors are available as replacement parts with different oil capacities, therefore note capacity on the A/C compressor and the exact part number. Refer to the Parts information and REFRIGERANT R134A CAPACITIES .
  
  Depending on A/C compressor type, different refrigerant oil capacities may be designated for the refrigerant circuit. The reason for the different oil capacities in the A/C compressor for an otherwise identical refrigerant circuit is the design of the compressor. Observe these oil capacities. Too much oil in the refrigerant circuit increases the pressures and reduces the cooling output of the A/C system. Too little oil can result in lubrication problems in the A/C compressor. .
  
  When installing refrigerant lines and the corresponding brackets, make sure there is adequate distance to the other components (such as the belt, engine belt pulley, etc.).
Refrigerant Line Connection To the Evaporator in the Battery Cooling Module
- Low pressure side
  WARNING:
  - The bolts of the connection point may only be loosened when the refrigerant circuit has been discharged.
Hybrid Battery Refrigerant Shut-Off Valve 1 -N516-
- Installed in the left plenum chamber
- Check the Vehicle Diagnostic Tester in the "Guided Fault Finding" function
  NOTE:
  The Hybrid Battery Refrigerant Shut-Off Valve 1 -N516- is activated, for example, if it is necessary to cool the battery and no cooling is desired in the passenger compartment (open without activation).
- Removing and installing. Refer to Hybrid Battery Refrigerant Shut-Off Valve 1 -N516-, REMOVING AND INSTALLING .
Refrigerant Line Connection to the Evaporator in the Battery Cooling Module
- High pressure side
  WARNING:
  - The bolts of the connection point may only be loosened when the refrigerant circuit has been discharged.
Information Label
- Indicates type of refrigerant and intended capacity. .
Electric Drive Power and Control Electronics -JX1-
- Read and follow all of the supplemental warnings for all work performed on the Electric Drive Power And Control Electronics -JX1- and vehicles with the high voltage system. Refer to HIGH VOLTAGE VEHICLES SAFETY PRECAUTIONS .
