the fix is now official over in the vw paddock.
more details here in the mk6 forum.

hopefully skoda aus come to the party too and provide this fix under warranty.
i emailed my dealer yesterday, who has passed it on to the skoda techos and product manager.

will keep u posted on the progress.

i've had the rattle since new. not the end of the world, but surely an annoyance and sometimes embarrassing.
fingers crossed skoda end my rattles.
