Yuppdahee: Der Hersteller hat geantwortet:
" I have checked and the PKC is flashed to the latest (part of 2.1).
From your serial number your key fob should have automatically flashed as well. Unfortunately, we are not able to confirm this remotely.
Additional improvements have been made to improve the battery life in the next PKC release, which is part of 2.2."
Na dann brauche ich auch nicht mehr rätseln.
