My 528i does, or did the same thing. Overheating is bad for those aluminum cylinder heads. 1st, replace the coolant. Then check to see if the electric cooling fans work, or cycle on, they most certainly would have to cycle on when the temp gauge is in the red zone.
1st thing most people do is replace the thermostat. However, if the temp goes from overheating to not overheating in less than a minute, the thermostat is working. The key thing to look for is why did it get to the red zone in the first place.
