Car shows -40 celsius and no air is coming out

[joojo]

My fan system has stopped working, no air is coming out.
The temperature shows -40 celsius, while where I live the temperature is 5 celsius.
I can't change the speed or change the temperature
Has anyone experienced this and have a solution?
The workshop visit is in 2 weeks...

Press and hold the physical Home button for 10+ seconds until the infotainment system resets. See if that helps.

Did that without a result, I have done a system reset too without any results.

A call to your dealer is probably in order.

Is the external temperature sensor broken or iced over? You can see it poking through the front grill next to the front number plate
