Had an annoying rattle from the rear which was driving me insane over bumpy/crappy roads. It shounded like the boot lid was loose. Took it apart 3 times yesterday and it fried my brain for a couple of hours trying to find the culprit. Luckily a mate with a Sharan dropped by and said it’s the half taillight part on the lid 100%. I was like no way untill he took it off and started jiggling it
The round reflector part surrounding the fog light was loose in there. We ghettoed it away by drliing a small hole and fitting a thin screw to keep it in place and not moving. Problem solved, no more rattles.
Here’s a vid of the noise and pic of the culprit.
