Hi everyone. I've got a 06 Coupe with 26k miles on it. About two months ago I noticed a slight rattle that I hear inside the car around idle or just above idle. It's coming from the engine compartment. But you can hear it best inside the car. It sounds a bit like there is a loose plate somewhere rattling slightly against another plate. It goes away if you're above idle. Has anyone experienced anything similar? I'm wondering if it's a known problem. It hasn't gotten worse.
