Im happy to help you.hy,
i have the same problem like you. I have an i30 N-line with panoramic roof and when the weather is not warmer i have rattle on the pano roof.
I have allready fix the rattle around th sunglasses holder but i have have noise on passagers side.
My dealer in France Don't have any note or any notice to fix that and i know me, when de summer goe out, i want to be crazy by the noise.
i read you notice and i have a question about the headliner. It's just fix with torques or it's glue somewhere?
I am happy to have found help here because this car is fantastic but the noise of the roof makes me crazy.
I think that the noises do not come from the panoramic roof but only from the roof sky insulation
The roof is not glued anywhere, you need to remove the parts i have listed in previous post.
