Default CZ: Brake

Hello, a week ago I got a parking brake error on the on-board computer... Currently the thing is that I can brake the car with the parking brake but I can't unbrake it anymore.

Error:

02443 control head
012 - Electrical Fault in Circuit

I followed the other posts and so I replaced: parking brake button, parking brake control unit (I bought 2 pcs and each one has the same error as before)

The cables to the motors are not rotten... Even when I run the parking brake test in the vag com everything goes fine..

Unfortunately I don't know what to do anymore.

And no other errors anywhere? even if they don't look to be an issue? Can you post the entire log?
Not trying to be difficult, just helps to have the whole picture.
