Did you check out the DIY(do-it-yourself) section? How way miles on your X? As stated on many of the threads here, the water pump on average gives out between 60-80,000 miles. If yours falls into this range, there is an excellent aftermarket water pump with stainless steel impeller (BMW's is plastic, which is why it fails. Why plastic? Damned if I know. It sure isn't an attempt at weight reduction) Anyway, it's only available for your 3.0. Myself and other V8 owners are stuck with the OEM part.
