Capacities For AUDI Q7 (4M_) From My 2016
The capacities for refrigerant R134a can be found in the vehicle-specific repair information. Refer to the appropriate Service Information. .
On the Audi Q7 e-tron there are differences to the other vehicles additional components installed in the refrigerant circuit. For the layout of the different refrigerant circuits, refer to Refrigerant Circuit (vehicle-specific repair information).
Due to the layout, the high pressure side service connection in the refrigerant circuit is located on the Audi Q7 e-tron on the high pressure side service connection only when operating the refrigerant circuit as a high pressure heat pump. In the A/C system operation the pressure is the same as on the low pressure side service connection.
To discharge, evacuate, and charge the refrigerant circuit on the Audi Q7 e-tron the valves installed in the refrigerant circuit which are power operated are opened. Activate and open the valves through a routine stored in the Thermal Management Control Module -J1024-. Refer to Refrigerant Circuit (vehicle-specific repair information) and use the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.
