• The compressor run-in takes approx. 120 seconds.
• The contact points of the electrical air conditioner compressor V470 and the engine must be checked prior to installation.The contact surfaces must be clean, rust- and grease-free.

📋 Procedure

1. Observe safety precautions when working on the high-voltage system Safety precautions when working on high-voltage system.
2. Observe safety precautions Safety precautions when working on air conditioning systems.
3. Observe safety precautions when working in the vicinity of high-voltage components Safety precautions when working in the vicinity of high-voltage components.
4. Comply with notes Working on refrigerant circuit.
5. Observe the risk rating of the high-voltage system Electric drive00Risk category of the high-voltage system.

6. Now de-energise the high-voltage system Electric drive93De-energising the high-voltage system.
7. Detach front part of front right wheel housing liner far enough to gain access to electrical air conditioner compressor V470General body repairs, exterior66Wheel housing liner; Assembly overview – front wheel housing liner.
8. If fitted, push noise insulation of electrical air conditioner compressor V470(5) aside or detach it partly in order to gain access to connectors and bolts.
9. Using , initiate basic setting, then perform function "Charge refrigerant circuit". [Note: Always perform the basic setting "“Charge refrigerant circuit”" using the , to make sure that all valves of the refrigerant circuit are opened. This is the only way to extract the complete refrigerant from the circuit.The must not be disconnected from the vehicle during the entire extraction, evacuation and charging process.To prevent the intrusion of moisture, all components of the refrigerant circuit which have been opened must be sealed with suitable plugs.]
10. Extract refrigerant with air conditioning service station. Comply with notes .
11. Separate connector (2) from electric air conditioner compressor V470(5).
12. Separate high voltage cable (3) from electric air conditioner compressor V470(5).
13. Disconnect earth wire (4) from electrical air conditioner compressor V470(5).
14. Disconnect refrigerant lines (1) and (6) from electrical air conditioner compressor V470(5).
15. Remove bolts (7).
16. Remove electrical air conditioner compressor V470(5).
17. Using , initiate basic setting, then perform function "Charge refrigerant circuit". [Note: Always perform the basic setting "“Charge refrigerant circuit”" using the , to make sure that all valves of the refrigerant circuit are opened. This is the only way to charge the complete circuit.The must not be disconnected from the vehicle during the entire extraction, evacuation and charging process.If the component has been renewed due to a mechanical defect (e.g. wear), purge the refrigerant circuit.]
18. If the electrical air conditioner compressor V470 has been renewed, the compressor run-in must be carried out using the . [Note: The compressor run-in takes approx. 120 seconds.]
19. Upon completion of compressor run-in, use the to clear event memory in thermal management control unit J1024.
20. Only start engine after refrigerant circuit has been assembled.
21. Only start engine when refrigerant circuits are charged. [Note: The contact points of the electrical air conditioner compressor V470 and the engine must be checked prior to installation.The contact surfaces must be clean, rust- and grease-free.]
