Yes, there IS a low coolant light AND an over heating alert light as well. For the over heating light, first there is a yellow and then a red (!).
The red stick inside the coolant expansion tank should be(atleast!) level with the top of the tank when the engine is cold.

As for how long the water pump will last... I think it depends on who the supplier was(I am sure bmw has more than a few suppliers) and how good the bearing inside the pump was. Its all a crap shoot.
