Came here to say I should have preemptively changed my fuel pump. '04 3.0i with 195K mi died tonight, on Christmas Eve, with three people in the car, at an intersection, in a snow storm, 20ºF outside. I kept telling myself "eh, it'll last" until it didn't and the pump went out literally at the worst possible time. Temps plunged today and I think the cold got it.

My advice after 15 years of BMW ownership: add it to regular maintenance around 150K mi.
