It seems even with entire new fuel tank/pump/lines etc BMW still can't get this design right.

Hmmm, it just came back for me also. Not sure if coincidence, as we're coming out of winter and it happened after I filled my tank also. The noise is very slight but I still hear it. I haven't replaced anything related to this humming noise but it's discouraging that even w/ some members replacing 'everything' the noise is still there. Will report back after my next drive.
