Expansion Valve, Removing And Installing (Front A/C Unit): Notes

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Audi S6, 2018 Audi A6 Quattro, 2018 Audi A6, 2017 Audi S6, and 2017 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.

Special tools and workshop equipment required 

WARNING:

Danger due to refrigerant coming out under pressure.

Danger of frost bite to skin and other parts of the body.

  • Extract the refrigerant and immediately open the refrigerant circuit after that.
  • If the refrigerant was extracted more than 10 minutes in the past and the refrigerant circuit was not opened, extract the refrigerant again. Pressure in the refrigerant circuit is caused by evaporation.
NOTE:

Certain tools are required to discharge the refrigerant circuit. These work procedures may only be performed by trained personnel. .

There are different versions depending on the refrigerant (R134a or R1234yf). Refer to the Parts information.

NOTE:

After switching off the A/C compressor in this vehicle, it may take a relatively long time for the pressure on the high pressure side to decrease. This is because the expansion valve is cold and the pressure on the low pressure side increases quickly after shutting the compressor off, then the expansion valve closes and the refrigerant flows slowly to the low pressure side.
