57 / E57
Sweating in cooling loop at low ambient conditions
This code typically points to
- Refrigerant leak
- Low charge
- EEV issue affecting superheat control at low ambient
- Thermistor issue causing incorrect EEV response
Next checks to confirm
- Test for refrigerant leaks
- Verify refrigerant charge
- Check EEV operation and thermistor readings
- Verify suction and discharge temperatures at low ambient
