HELP!! Noise coming from under car - BMW 320D

[Wg93]

So i have a 2008 BMW 320D and I have taken it to 2 garages. One says my gearbox might have gone, the other says it's my clutch bearing.

There's a noise coming from under the car (possibly under the front drivers seat) - I have a link to it below.

The noise sounds like something is rotating. When I'm in neutral & stationary, the noise is slow and low. The faster I drive, the faster the rotation gets and it gets louder.

While the car is moving, If i change the gear to neutral, the noise goes. As soon as I get back in to gear, it comes again.

Any experts out here that can help me out please?

Please see the link to the video recording the noise - https://www.youtube.com/watch?v=TX4v7ggG-R8

Sorry can’t help with the noise, but I did notice your engine management light is on.

Actually on a BMW (somewhat confusingly) that's the emissions control light. The engine management light is the one that looks like a squiggle. Still, get the light diagnosed, it might reveal something useful. On my OH's 120d it was the EGR valve that was clogged when the "picture of an engine" light lit up.
