Yeah it seems that BMW probably tops off the coolant every oil change to hide that the car is boiling the coolant off, I was under the min line by a good 6-8oz. My engine has been off for 4 hours and was still pretty hot but not boiling, when i opened the cap some steam coolant still came out. You don't pay attention to something like this and a few hard pulls and bye bye motor.
