You are absolutely right. Apparently, in my controller, whichb I only use for slew options, steering was connected . Great. Thanks so very much. All systems A oké now.
It is strange. I have done the following:
1) empty community folder
2) start up the sim on the runway
3) released the parking brake. When the airplane started to move I could steer left and right.
4) stopped the plane, applied the parking brake.
5) released parking brake again. Now I couldn't steer anymore (just like before going straight).
I now enabled the community folder
1) from the beginning no steering possible
Thanks your interets. It happens every time. Attached a small vid. No difference whether nose wheel steering is on or of in the both EFB or Control options. This is the result.
