BMW was documenting 100NM up to 2 years ago.
Since 2 years ago, all BMWs need to be tightened at 115NM.
For wheels with diameter greater than 17", you need to drive the car 10km or more and then check again.
Over tightening the nuts is a very bad idea for 2 reasons :
1. It might bend the hub of the wheel
2. When the brakes + wheels overheat, the nuts can break
I have seen both ^ in customer's BMWs.
I think you would have to seriously overtighten to cause any of those issues Alex, and our BMW;s use bolts.
