Car is a 2006 Elise.
After driving a good bit, parking, and turning the car off there seems to be a high pitched buzz coming from the cluster of stuff in the engine bay attached to the drivers side of the firewall. It sounds almost like a capacitor kind of buzz. I'm not toooo concerned about it, but I was just wondering what it was. Ideas?

I think someone figured out this is a cracked bracket which holds the airbox to the subframe. I'm actually going to check this on mine right now.
