It comes from what sounds like behind the instruments cluster. I thought it was the cluster so I removed it and took the car for a drive and the rattle was still there.
It only happens if you let go of the throttle at exactly 2500rpm and rattles till the revs drop below 2250rpm or you put your foot back on the throttle. It sounds like a phone vibrating behind the dash.
And if I can't sort sort it soon I'm going to have to get rid.
