Don't expect any warranty coverage from BMW on drivetrain components (i.e. engine, transmission, differential etc.). I have had no issue whatsoever with BMW covering non-drivetrain related components (my most recent issue was electronics with daytime running lights, which BMW covered under warranty no problem). As others have said, it is dealer dependent.
