Early 90's 735il's had this "feature" as well.  I had leased
such a beast (awesome road car BTW) in 1991 and upon taking
it in for its third or fourth oil change, they pointed out I
had blasted past redline three times, and warned me that
this could violate the engine's warranty.  I argued and said
"That's what the rev limiter is for - to protect the
engine", but the service guy insisted he was in the right. 
Not in the paperwork, too bad.  But, still, the point is I
brought the car in, they knew I had pegged the tach three
times.
