If you are losing a gallon of fluid every couple weeks or so, and your dealer could not find a leak that big, then you need a new dealer. As for filling it, just go buy the same blue stuff for any car for a couple bucks at the auto parts store. There is nothing special about washer fluid even if BMW tries to convince you that there is. Then keep track of how long it takes for your light to come on, and how much you actually used it. The fluid does not just evaporate.

sorry for not making it clear. I would say both.
first one is the fluid will really go low after a refill without being used.
also from time to time, it is not really low, but the car will "think" it is low after a sharp/hard turn. I guess this is just the fluids shifting around in the tank and the sensor misread.
