I keep getting an annoying rattle on roads which vibrate the car, it sounds like it is coming from behind the dash to the right of the steering wheel.

Has anyone had this? Wtf is it?

When does it happen? Speed, revs, bends? Is it a clicking sound? Is it only aural or do you feel it through the wheel? Would you be able to record it and post an excerpt?

Most common cause of a rattle, which can appear to come from anywhere, is the button on the handbrake. Just touch the button when you hear the rattle to eliminate this cause. If it is the cause, just trickle a small drop of oil down the side of the button.
