-Take the door cards off (undo 4 screws for door handle (2) & door catch & window winder) and pull the card with its clips
-Tighten the screws of the plate the window winder goes into - this was causing a bit of rattle on mine
-Where the bar from the door opening handle at the front of the door goes to the latch towards the rear of the door (rear of the car), that seemed to be slightly rattling at certain engine revs/vibrations against the inner part of the door. I bent that ever so slightly away from the door so it wasnt metal to metal and it seems to have cured it. Don't push or bend too much.
This is obviously a brief experience I have just had an its open to any further tips/comments but it will add to the list of rattles you might be able to find..
