The car came back from the dealer on Tuesday and their fix was to update the software from 1788 to 1803. I went for a run yesterday and although initially OK the kph syndrome kicked in. For example enter a 50mph zone, dynamic sign display reads 80 (kph) (even though it reads 50mph on the sat nav display) ACC sets to 50mph , pass another 50 sign and the dash display changes to 50 (kph) and the ACC changes to 31mph. No difference from before. Anyone have any recent fixes or success?
