Everything points to it being the coolant sensor or the pump, but BMW have said they are fine, so I am at a loss as to what else it could be
What is your mileage, and how old is the car? Looks a lot like a failing water pump to me, as this is exactly what happened to me. Could also be a failing fan. So you need to buy a code reader like the peak scan tool, and pull the code to find out what component is wrong. Guessing at it, isn't the right approach.
