Overheated 2002 bmw 330i

So one day i was driving my car and the gauge went to the red and i pulled over right away. After it cooled down i turned it on and let it run for a bit and the gauge stayed at normal temperatue. I decided to drive it and the gauge went to the red part of the gauge again. So what im tryna say is when the car is on amd stationary it doesnt seem to over heat it only overheats when i drive it. Any advice will help.

Usually it's the other way around if the water level is a little low. The only thing I can think of would be a bad/broken water pump impeller. An engine puts out more heat when under load than when idling. It gets hot when there's no water moving thru the block and/or airflow thru the radiator. As much as it sucks to hear, resign yourself to the task of a head gasket change either way at this point.

This is exactly what my car did when the head gasket blew. It would idle all day and be fine but the second i tried to drive it it would overheat. It was pushing compression into the cooling system. Go to the parts store and rent the "block test kit". It samples the coolant and detects if any combustion gasses are getting into it. I know autozone has it, not sure about anyone else. Also on mine when i opened the bleeder screw it would push contant steam out, no liquid. Pretty clear sign right there.
