As the other friend pointed out for you, this issue really came from a: faulty coolant temperature sensor. But I also wanted to add something more by saying that: (You should'n never mix any more fresh cold coolant in the car after the engine been running Hot!!!) As it may cause some type of dilatation at the gaskets area to go bad where the hot antifreeze travels through. (I strongly recommend you to wait N'till the engine gets cooler, and add some BMW Antifreeze @ the appropriate level.
