Hello everyone,
The car I have is: Skoda Fabia MK3 Kombi 1.2. TSI 110KM 2015
Problem: The air conditioning stops working at temperatures of 30°C and above. When it's colder it works normally.
The car has automatic air conditioning.
What was fixed:
The car was at the air conditioning service and they replaced the air conditioning compressor control valve.
The service couldn't find anything, so they acted blindly.
The only trace that was on the computer and was repeated when there was a cooling problem:
590081 [0x090101]

After replacing this valve, unfortunately the problem still persists.
I read somewhere on the internet that it may also be the fault of the air conditioning panel.
Not thinking much about spending blind money at the service center, I ordered an air conditioning panel.
I only ordered a newer 2020 Fabia 1.0 TSI car model.
After installing this new panel, everything seems to be working, but in fact whether the AC is "on" or "off" makes no difference. The air conditioning generally does not work, everything else works, but the air conditioning does not work even on a colder day.
When the new panel is installed on the computer, there is an error:
590087 [0x090107]

With the old panel, at least it works on cold days, but with the new one it doesn't even work on cold days.
Is it possible that the new panel has different parameters and is simply trying to start a different compressor than the one in the car? Maybe someone has an idea how to solve it or has already had such a problem with air conditioning.
Thanks
