Technical Background

Event Entry about Inoperative Expansion Valves (diagnosis address C5).

Production Solution
Optimized shut-off/expansion valve for heat pump from VIN: AU_LW912563.

Service
WARNING:
Extremely dangerous due to high voltage. Electrocution can cause death or very serious personal injury.
Have the high-voltage system de-energized by an E-Golf certified technician.
Observe the safety precautions when working on the high-voltage system. Refer to Safety Precautions
when Working on the High-Voltage System” in Elsa.
Pay attention to safety precautions when working near high-voltage components. Refer to Chapter
“Safety Precautions when Working near High-Voltage Components” in Elsa.
Pay attention to the high-voltage system danger classification. Refer to Electric Drive; Rep. Gr.00; HighVoltage System Danger Classification in Elsa.
 Connect the Vehicle Diagnostic Tester and extract refrigerant.
Note:
It is absolutely necessary to perform the basic setting “C5-fill the refrigerant circuit” using the Vehicle
Diagnostic Tester so that all refrigerant circuit valves are open. Only then can the entire refrigerant in the
circuit be extracted.
Do not disconnect the Vehicle Diagnostic Tester from the vehicle during the entire extraction,
evacuating and filling process.
There is a risk of damaging the AC compressor if the refrigerant circuit is empty. Never start the vehicle
with refrigerant circuit empty.
