The question is: What can i try? I think probably the KBM is the problem, but everything works fine, so i don't know where i need to start

I had this issue pop up the other day as well. Fortunately for me it ended up just being the drivers seat module. I figured I would just start unplugging modules one at a time and rescanning for codes and hope they would go away at some point. If that doesn't do it, probably a wire on the bus somewhere that is broken. When I unplugged my driver seat module the errors went away and returned when I reconnected. Fortunately I found a used module on Ebay for $10 that's on its way. Seat modules are the quickest thing to disconnect, also some of the modules in the trunk.
