Doesn't seem like there is much of a consensus as to what it is or if it is even harmful. @Chrisar82 mentioned something about changing heads, but he has a 128i, not a 135i or 1M.
The other noise that bebo-valdez brought up was the common dual-mass flywheel rattle noise that goes away with the press of the clutch. This is a well known noise that affects many cars with dual-mass flywheels.
