I have a rattle on my IS200 which I thought was in the steering column, but I took it apart and couldn't find it. I also took the footwell dash panel off and couldn't find anything behind there either, I checked the bonnet release, the throttle cable and loads of other electrical cables.
The noise sounds like a loose piece of metal rattling against something, it's quite quiet, but on rough roads it chatters quite a bit and it annoying, especially with the rest of the car being solid.
Has anyone got any ideas what else it could be? Sounds like it's coming from drivers footwell but I guess that means it could be anything behind the dash even at the top (behind instruments), as the sound would exit through the footwell (if that makes sense?). It's definitely inside the car.
Has anyone on the forum heard of anything like it before?
