I'd say it's a combination of those two.
I've had 3 water pumps fail in the 15+ BMW's. The ones that did not experience failures were typically because I replaced them before failure. Any BMW water pump +100,000 miles is starting to hit borrowed time. I replaced them in all BMW's that got flipped.
In the future though, unless the owner can prove they replaced the pump and thermostat in the last 30,000 miles... I'd insist on a water pump and thermostat while doing the guides. I couldn't imagine doing all that work and not doing those 2, in addition to tensioners, and other front end components.
^That's just my .02 though obviously. You keep doing you as it's obviously been working for you.
