E86 Dash rattle

[sd_dracula]

I get this annoying rattle coming from the passenger side when driving on uneven roads and since I have all the dash trim, vents, centre console, out of the car, I was wondering if I can fix this too.
Now I have no clue where it is coming from but where are the key places where this happens on the passenger side?
The vent? The glovebox?

Check the braces under the bonnet. They are known to come loose.

I've done that already about 2 weeks back, I remember reading about it on the forums.
I wonder if those clips that the vent screws go into can cause they are a bit wobbly.
