(Please correct if I am wrong) From what I have read and understand the typical situation (not money shifts or over revving) is the crank hub slips a little. This throws the timing off and the computer puts the car into limp mode or if it has slipped enough it prevents the car from starting. This is done to prevent any internal engine damage. BMW then has to replace the crank hub, bolt and retime the engine.

Does anyone have an accurate repair bill from BMW when their car has gone into limp mode or not starting from the crank hub slipping? What was replaced/repaired?

That would be the deciding factor for me in any pre-warranty expiration mods. From my understanding we are not talking about total engine replacement just a new crank hub, bolt and re-timing.
