Had exactly the same Lons, got customer services involved and version 12 was installed in April, these dealers should be held to task for "not telling the truth". Customer services phoned the dealer for me and within 3 hours the dealer had phoned me to say they had just received version 12 - rubbish.
In dispute with BMW at the moment, this morning my wife received a safety recall notice saying she needed a plate fitted under fuel pump as if there is an accident there is a possibility of a fire. The update takes about an hour, phoned dealer and they said that they would need the car all day, I requested a courtesy car but have been told they don't supply them for recalls. Now waiting for the service manager to call to "discuss".
They could have lost a Ł70000 sale through this as I was considering the new X5 when I change.
All dealers appear to be the same once they have sold you the car.
