Okay, let's say three.

No, TWO!

Okay, let's get back to being factual, otherwise Ecker will complain .

PS: I had not heard before that air control flaps had detached from the actuator(units). *note* But one never stops learning.

I've read the error code again.

Refrigerant pressure - Lower limit exceeded.

It used to be sporadic, but now it's constant.
The pressure gradually decreased from approximately 8 bar to 0 bar.
The compressor shuts off when the value is 3, which indicates that the refrigerant pressure is too low.

Is that definitely the expansion valve?

Serdar.

If the compressor is working properly, there is enough refrigerant in the system, and you hear a hissing sound inside, then yes.

P.S. Please don't focus too much on the expansion valve. I'm not sure if you have one. I mentioned above: expansion valve/fixed orifice.

Sure, we have one, and that's what it's called.
As I mentioned, there was approximately 8 bar of pressure before filling, and there was still pressure afterward. Then, with the hissing sound, the pressure slowly decreased until it reached 0 bar after about 2 weeks of hissing.

What exactly happens technically inside the expansion valve? I read somewhere that the phase change from liquid to gas occurs precisely at that point, and then the gas flows into the interior.
But what happens to the refrigerant if the valve is defective? Does it escape somewhere, or does it remain in the cycle only in its liquid state?

Best regards,

Sorry, but I've explained it so many times, I don't want to do it again. Here is everything:
Okay, I'm ready. Please provide the German text you want me to translate.
