SEAT Leon Service and Repair Manual / Heating and air conditioning / Air conditioning system / Refrigerant circuit / Removing and installing refrigerant circuit pressure sender - G805-


Danger from refrigerant escaping under pressure! Freezing of skin and other body parts.

  • If when loosening the G805 refrigerant escapes for more than 1 second from the coolant line, the G805 must be retightened. The non-return valve in the refrigerant line is defective and must be replaced.
  • Evacuate the refrigerant and then open the refrigerant circuit immediately.
  • If more than 10 minutes have elapsed since evacuation and the coolant circuit has not been opened, evacuate the refrigerant again. Pressure builds up in the coolant circuit as a result of secondary evaporation.


  • Detach the electrical connector -2-.
  • Screw out the pressure sender -1-.
