I'd probably plan for it at like... 80k miles if the car hasn't had it replaced already. Before that, eh. They all seem to be lasting about that long at the minimum, and I seem to recall a few E82/E90 people pushing the original pump to like 140k in forum banter.
And with some miles on it, it may have been replaced already.
oil filter housing gasket, valve cover gasket, coils and cooling system will all come due with some age.
