Moin people, I have a problem with the ZV of my father’s Leon. the SuFu via Google has unfortunately not published anything suitable. to the problem: ZV does not work via radio and also not via keys. inside in the car at the door already. So nothing can be done by radio, via keys can lock when all doors are open, the key only opens the respective lock where you turn. If everything is closed and you turn at the door lock only the driver door opens. The car battery has been changed, according to my father also good because the car starts immediately. Backups also OK. Unfortunately, the new programming of the key did not succeed, but think that it is not because it is not possible manually with the key. Microswitches should also be all OK because all door lights work, all doors have opened separately. What could it be on? What can I check? thank you already in advance. Greetings
