Are these noises normal?

[TylerD]

My car makes some strange noises and I wonder if they are concidered normal for cars with N55 engines.

1. A whining/humming sound from the engine bay driver side, that can be heard from the inside. It gets louder when the clutch is pressed and rpms get higher. At rpms higher than 1500 it cant be heard anymore.

2. Vacuum leak like hissing sound coming from somewhere around the instrument cluster in the dashboard. (read something of a vacuum leak in mpg gauges, but I dont think newer cars still use such a thing)

3. A strange metally (maybe engine) sound around 2000-2200 rpm. Cant really describe it. Will try to make a video of it, but I dont think that its loud enough.


The first two sounds can be heard in this video:

Any ideas what that could be?

Thank you very much!
