Water pumps do fail. Lots of people, including the Roundel tech guys,
prefer to replace them at some interval (ranging from 60K to 100K miles.)
However, when they do fail, it's usually not a big deal as the leak from
the bearing is easily evident. Caveat: if you have one with a plastic
impeller it can clog engine/other coolant passages and the engine will
probably die.
Given all that, the radiator and especially the expansion tank can
fail catastrophically and you'll probably lose the engine, unless you
IMMEDIATELY stop it.
I've got a '01 330xi; I've changed the radiator, expansion tank,
thermostat and hoses (at 100K) but still have the original pump.
YMMV.
