Gentlemen, there's a new problem.
When the above mentioned idle does not occur and you can go, the following error starts to appear while driving: Gearbox warning, and the number with the gear engaged flashes. The gearbox is still working normally, it shifts gears, but you cannot switch to manual. After stopping and engaging neutral and gear again, it is quiet for a while, then the situation repeats itself.
I reread the errors, but apart from the ones above, only one unknown appeared:

Where to start here? Do I have to find an electrician?

I would go over the installation again.

After the car was stopped, there was a frayed cable in the weave to the box.
