Well I had a look at the weekend .. trim came out really easily but I couldn't find anything in there that was suspect. Coupld of wires resting on outside of car I moved away and funny little box (like a transformer bolted into the side of the car that again I moved away slightly from outside of car. Put it all back together and got the same rattle.
Thought I would move the seats to see if that is the issue folded up and put some silicon spare on all the runners and the springs and relocated. Unfortunately I still have the same rattle.
On normal driving I have nothing at all ,even over speed bumps etc nothing. Its when I hit small ridges and sends a jarring through the car, thats when it sounds loose somewhere but I can't workout where ... I had a look underneath car but nothing looks loose ...
any other suggestions ??
