For a few days, the following phenomenon has been observed:
In the morning, I'll start the big guy and go....all good. A few kilometers later, I stop at the kiosk. I start the engine again, and see how an LED flashes in the climate display (old climate). Now it's cold air. The blinking stops after about 1-2 minutes, but it still only comes cold air. Even putting up the Themperatur hardly brings any improvement. After a restart of the engine everything is as it should be.
What could that be... where should I start looking?
