EGR + AIR Help
As long as it didn't drop near anything that is moving it should cause any harm.If it fell INTO the engine that will cause harm.
You can worry about how you get it out after you find it

Obviously you'll want to find this if you can. Just don't lay awake at night worrying what damage it will cause if it only fell into the engine bay.
Try to get the vehicle in better light and look again.
