What looks like a whacking great piece of pig iron behind the battery box covering the ECU is loose on my car and I'm sure it's rattling away under the bonnet and I can hear it whilst driving. I want to remove it to see if the rattle goes away. What is the point of this thing and is there any likely hood of problems if I leave it off (must be there for a reason). Alternatively does anyone make a more refined aftermarket cover - something a bit lighter than the great big standard chunk of metal lol.
