Hey guys, my 2007 328xi e90 has been making this weird noise for the past couple months. I have done research and haven't found anything that resembles the sound I am hearing. It never gave me any noticeable issues so I haven't really done anything to try and fix it. However, I recently started to get an occasional rough start, and receive a p114d "manufacturer control" engine code that comes on and off. I attached a video of the noise, although the sound is more noticeable in person than in the video. Anybody have any advice or experience the same thing?

I have an N51 as well and this does not sound like my issues (vacuum pump and power steering pump failed). The pump sound makes me think its something air focused and possibly crankcase related.
