Hey everyone I'm Adam, new here. Have a Silverstone 03 GTI VR6. I'll post a couple pics of my car later on.

Got a question..
I have this strange rattling sound coming from the front end of my car when I turn the key just enough for all the electronics to start up but not the motor and i get a nasty sounding rattle from the front of my car. it sounds like a penny on a vibrating metal surface.

I had the larger of the two radiator fans replaced yesterday for other reasons and i'm replacing the ect sensor in a couple of days from the faulty black to the updated green sensor.

any ideas?? I've used my googling skills to no avail..
