My dealer is Schmidt cars close to Munich. They had quite some troubles but were finally able to update the software. I've got my car back and it runs quite well and doesn't show any error messages so far.Who is your dealer/agent? Have the problems been solved? Do you have your vehicle back?
I am asking as I have been told by my agent that the only thing stopping them from handing over my vehicle to me is the software update gone wrong (odo and remaining range gone blank).
