my car is a 05 545i with 81k miles, so what's the life expectancy of the water pump? Should I just go ahead and change it now, rather than get stuck on the side of the road in the near future?

Replace with quality unit that has metal impeller, and do belts, hoses, expansion tank, thermostat, sensors and coolant flush also.
Good knuckle-busting, money saving Saturday for DIY - or pay the Indie.

30-130k Seriously I've read of them failing everywhere and anywhere in that range so its pretty much a crap shoot. I think the recommended is 100k but just go for it if you want some peace of mind. Still going strong here at 87k on the N52

I bought a little cigarette lighter voltmeter which I use to monitor voltage and keep an eye on the system.
