I have been struck. 2011 335i with 82k miles. All preventative maintenance done, oil changes with BMW 5W-30 every 6k miles, never drive the car hard until oil is up to temp.
Driving around 50 mph in 4th gear and I feel a slight hesitation but no weird noises, turn into my driveway and put the clutch in, RPMS drop to zero and the car wouldn't start back up. 20 minutes later the car fires up and drives normally. The next morning it developed a knock.
