[HELP NEEDED] BL Touch defect, bought new one, Auto level won't do

[KleinerKobold]

I get the following error on Autolevel:

I did everything that is described here: https://github.com/knutwurst/Marlin-2-0-x-Anycubic-i3-MEGA-S/wiki/BLTouch-Installation-(deutsch)#ermittlung-und-konfiguration-des-z-offsets

The BL Touch does not go down on point 2. And that error comes up.

What can I do to fix it?
