Update, same thing happened a second time, got stranded at the gas station a week ago.
Funny enough just across the street to my BMW dealer.
Unfortunately no option but calling the road assistance to move the car across the street.
After checkup its throwing all sorts of random error codes, and one of them TCB connection error, for which the service instruction is software update.
Long story short, car was updated with latest software 03/2023.53 and back in my driveway today, lets see if this is the solution or more "fun" to come..
