The coolant level sensor needs to be in the correct position, otherwise it will measure coolant incorrectly. Maybe it won't cause much trouble to hang it loosely, but as the BMW owner, it is a legally binding requirement to do things correctly

The sensor has a notch on it, and it should be a slot connected to the hole at the bottom of the coolent tank. If you can take a picture it would easier to explain. You need to match the notch with the slot and push all the way in. It is not tight, just gently push in then twist to lock it into place.
