Ok, i started the car up today and as i moved it out the garage, i heard a little 'ping'. Anyway, thought nothing of it until i spotted this little thing underneath where the engine bay was.

Anyone know what it is as i dont have a bloody clue where its come from?!?!?! It might not even be from the car but thought id check to see if its anythings that fallen off.

If it IS from my car then im sure someone will know on here exactly what it is/does, but if it ISNT from my car i dont have a bloody clue what it is and how its got in my garage!
