My water pump went at around 40k. There were a few signs.. coolant level was low (but not extremely low), engine overheat minor came up on iDrive. The next day it failed and showed the same message but followed by a critical failure telling me to pull over and stop immediately.
Had it towed to the dealer, replaced the pump under CPO.
Btw- even with autoclear on it will show a check engine light that WILL be visible, but it will reset itself and disappear. The menu to disable autoclear is 1>4.
