Your new engine may be fine and you may never have any trouble..... Only time will tell. If you want to see how the new engine is doing, take oil samples at every oil change and if there is a clearance issue, bearing material will show up on the UOA!
One thing of note to everyone, DO NOT, under any circumstances, put any excessive load on the engine until the engine oil is at operating temperature. With only about 0.001" of oil clearance and 10w60 in the crankcase, lubrication is going to be compromised until it is at operating temperature!

I am extremely careful when the engine is cold and try and stay below 3k rpm just for the peace of mind. Also with BPM Stage I incorporating 4k rpm limit when cold the chances of any damage is somewhat minimized at the hand of an idiot workshop boy at the stealership.
But given all these issues, surely BMW should build in some tolerance in this area given after all everyone one is human and can overlook this unintentionally.
