Problems with the engine fan

Hey everyone!

And once again, I'm having a problem. Can someone help me with this again?

After I turn off the engine, all the fans on the engine continue to run for up to 10 minutes before they finally stop. It doesn't matter if the engine is cold or warm; it always happens. Even if I only start the engine briefly and immediately turn it off, the fans keep running. My diagnostic device is showing me three errors: 18039, 17948, and 01314.

Thank you very much for your help.
Best regards to everyone!

Please enter the error code and your vehicle's make and model into the search. However, I will not comment on whether or not this is related to your specific issue. Please also check the thermal switches and, if applicable, the fan control module.

I've already tried using error codes and MKB codes. However, the specific information I have is that component G79 is damaged. I don't know if the fan has anything to do with it.
I will check the thermal switches tomorrow. Where are they typically located in an ASV (Automatic Voltage Stabilizer)? Perhaps someone has experience with this? Thank you for the information, anyway.

What does the donor say about the KW temperature? Are the values somewhat plausible for a cold engine and a warm engine? Perhaps the problem originates there.

The kw-temp sensor seems to be working correctly, and all the signals appear to be quite plausible. I will double-check it again tomorrow. Thank you.
