Same here took car out with the sales rep, <200 KM on odo and both he and I took the motor to 8400 rpm with no limitation. Sounds like bogus rumors.
What exactly does everyone think is getting broken in with these motors? Its the rings only. I have race motors that get dynoed at full rpm and then run at the track. There is no break in. Had to tear motor down sometimes for other reasons and they look great. Break in on modern motors is hardly needed. Granted BMW wants to limit rpm to <5,000 and they probably have good reason, but it's ultimately for long-term longevity and is doubtful that anyone will notice any difference in performance or longevity. My opinion only and if you want to argue that BMW engineers are a lot smarter than I am, you won't have any argument from me.
