Well, after getting back from Dunsfold and having to listen to the rattle in my door, I had a look when I got home. I removed the door card which was pretty easy... thanks to the forum
I found that I wasn't the first to enter this place, I found a missing screw behind the airbag plug, tweeter cover has a broken clip and the plastic sheet was torn in places.
I had a good mooch around and after taping and banging the door I noticed that the rattle was the side impact bar, it was loose on the front bolt. After tightening this, my rattle pain was no more.
I repaired the plastic sheet as best I could, and put it all back together. I now have a door that goes thud when shut... JOY
It may be worth checking this bolt before open door surgery takes place as you can get to it behind the wiring loom that goes into the door from the A post, it sits behind a plastic cap.
Does anyone have a spare tweeter cover for the drivers door and a screw that goes behind the airbag plug
Thanks.
