Hi guy's
Thank you for the tips so far.
It's been back to the dealer a coupe of times and they say they couldn't see/hear anything obvious when removing the top of the dash or test driving but did add more padding, the rattle is very intermittant and can happen on any surface except very smooth new tarmac and seems to be worse the warmer the weather, it's frustrating.
As for actually removing the shelf i managed to get step 1 (lifting the shelf from the bottom of the glove box) from the diagram done with a bit of effort, but still struggling with step 2 removing it from the side of the glovebox am i right in thinking it should just pull away?
