Vehicles with High-Voltage System (without Additional A/C System Functions, for Example the Audi A3 e-tron, Audi Q5 hybrid etc.)
The refrigerant circuit is cleaned in two flushing cycles (first the section with the evaporator in the front heater and A/C unit and then the section with the high-voltage battery heat exchanger or the evaporator in the battery cooling module). Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT .
For vehicles with two evaporators or an evaporator with a heat exchanger, disconnect the circuit to the second evaporator or to the heat exchanger from the circuit for the first evaporator using the manual shut-off valves and flush it in a separate work procedure. Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT and Refrigerant Circuit .
The design of the different flushing circuits for this vehicle is similar to a vehicle with two evaporators. Refer to Refrigerant Circuit with Expansion Valve, Receiver/Dryer and Second Evaporator .
