Hi all,

I've got an odd buzzing noise coming from under my 2007 328i Touring with an automatic. The car has 96k miles with zero fault codes, the engine doesn't skip a beat, and gearbox shifts mostly smooth. I notice the buzzing consistently around 1250 RPM or so but I'm unsure if it persists because other noises have higher volume after that point.

I recorded a rough video on my phone. I'll post the YouTube link for you to have a listen.

Don't mind the whine that sounds like a power steering pump in an old Ford. I'm having that diagnosed next week and I want to tackle one annoyance at a time.
