Hello guys. Last week i bought my first S2000 MY00 with 148XXXkm on it. My car has a rattle somewhere in dashboard on certain RPM. Between 2000 and 5000 it start to rattle. No matter if i drive or i dont move or if the clutch is in or out. When i brake hard the noise change a little bit like the thing that rattles change its possition, but i cant hear the change of possition(if it does) only the sound is slightly different. You can slightly hear it even when idling and also it is hearable near engine. I recored a video so you can hear it. Thx guys.

Does it rattle when your sitting still or only when you're moving?

Check the bolts on the side of the dash when you open the door, they're behind a little flap. Mine backed out make everything rattle.

Might want to try having a passenger put pressure on different areas (I.e. Brackets, panels, etc.). If it loose touching it will change the vibration frequency and you will find it.

Today i checked the side bolts. They were loose but i tighten them up and it doesnt help. Tomorrow i will try what you said Utah.

So i was trying to determine where is it coming from. I can clearly hear it when i have my head near the pedals, but i think it is not coming from dash but from the bottom of the car. It is hard to find out since the car is too loud when i press gas to start the rattle. And also i was braking down the hill to full stop and every time i was about to stop it sounded different from normal. Like some screw or metal ball or something is rolling there. It did every time i pressed the brake but it was not related to the brakes... Tomorrow i will try to check heat shields but i think it is not the reason it rattles

had a similar rattle, it was a loose bolt behind a plastic cap on the left side of the dashboard. it can only be accessed if the door is open an the cap is removed. I removed the cap and the bolt fell out, tightened it back up and presto, no more rattle. Hope you're as lucky as i was.

Thanks but it is not the one. None of those which can be accessed from the interiour. Today i was checking underneath the car and nothing is loose there. Not a CAT and also the heatshields are ok.
Maybe something in the ventilation? Some bolt or something???
