I've heard of a number of people who have run their car beyond the displayed remaining range to the point it just says -- miles/km without issue. But in BMW's defense...doesn't the manual recommend not running the tank below 50km remaining in order to prevent any possibility of engine damage? OP I don't mean to chastise you so please don't get me wrong, I'm just putting on my two cents.

Edit: I do admit though that it's scary the car records how low we've run the tank for x number of past weeks among other things.
