Weirdness

[fordel]

I was driving through town today, and all of a sudden my car started to make this strange pusling noise, like something hitting a bit of plastic on and off all the time.

Nothing changed with the way the car drove, so got it home and had a looksee.

There is a silvery box bolted to the firewall with some cables going into it, this is what is causing the problems, an actuator of some sort, yet i have nfi what.

Anyone got any ideas clues etc ?

Looks like its off to fraud this week to get it looked at.
