Is the rattling noise on the left side? LHD driver side? It could be the DISA valve rattling. Go get a cheap mechanic stethoscope at Harbor Freight. I have one. It's one my best tools to find rattles and noises.

Honestly....doesn't sound too bad to me. I hear the sound of the injectors clicking and the alternator whining.
Any fault codes for the VANOS? Maybe it's the VANOS rattle. That type of rattle sounds like this: https://www.youtube.com/watch?v=zAyQBiV5GbI

Listening to the video, When I rev the sound goes away, or it just gets overpowered by the revving. But I do not hear the same noises when I rev like in the video. EDIT: What are the symptoms of a failing alternator? |

I will be checking it out later today. I am going to take it out and see if the flap is messed up.

I took a video just reving it. I mean the sounds disappears while at high rpms. Just idle is when it sounds like that
