I know the N54 has a relatively new high-pressure, direct-injection fuel system with piezoelectric injectors. I understand that fuel pump failure is generally limited to a build date of 6/06-9/06. Any info on why the pump is failing? Also, I understand that the 760i V12 also uses this system. Any word on simliar problems with that model?

Thanks.
