@dc42 I have not been able to reproduce the dialog at all.
I got this result by using M98 P"config.g"
Only answer I get back via the terminal screen is:
ok<LF>On the screen I get a message M307 on heater 0 being overpowered (this is the bed), although the heater is swiched off.

That's common when you have a high-powered heater. It's warning you that you should install as thermal cut-out for safety.
Is your current problem the 2000C reading on heater 4? What does M308 S# return, where # is the sensor number (T parameter) that you specified in the M950 H4 command?
Please post your config.g file.

Sorry for the delay,
In fact the over power warnings were given without having heated anything. Also the bed is powered via a solid state relay. For now the message does not persist anymore.
De temperature issue of 2000C is caused by two problems but solved.
I'm using an encapsulated thermistor. nicely fitting in the heater block.
The contacts are not connected to the metal encapsulation, however when mounted in the heater block and fixed with the screw, one of the contacts is suddenly shortcutted with the metal housing. I ordered new ones.
In itself not a huge problem be it, it was caused by an issue with my lighting.
I'm using Cob lights which were screwed with plastic screws to the metal print head gantry. For some reason there was a metal connection between the negative pole of the lighting.Combination of the two issues resulted in the 2000C
The bed thermistor issue I did not solve yet.
