Vehicles with High-Voltage System (with Additional A/C System Functions, such as Heat Pump Operation on Audi Q7 e-tron, for Example)

The refrigerant circuit is cleaned in multiple flushing cycles. Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT  and Refrigerant Circuit (Cleaning the A/C system refrigerant circuit).

To flush, the circuit is divided into multiple sections and then cleaned during one flushing cycle at a time. It is divided by activating the installed electrically activated valves and using the installed manual shut-off valves. Refer to Refrigerant Circuit (Cleaning the A/C system refrigerant circuit).

The design of the different flushing circuits for these vehicles is described in the respective vehicle-specific Service Information. Refer to Refrigerant Circuit (Cleaning the A/C system refrigerant circuit).
