okay, I'm only replying because I also have a rattle from driver's side, under the engine. Mine though, is likely the throw out bearing, and is audible at idle. Also, it is rhythmic and goes away when I depress the clutch. Hope that helps. But, also I had a rattle about 25K miles ago coming from deep under the engine, and you could hear it at idle, and as it got worse, at particular rpms in particular gears...that turned out to be a new engine(bad bearings).
