Maybe something interesting for peoples likes me and their 6c that has some rattle coming from sunroof open or closed.
I had to replace my headliner due to water leaks and damages.
I took advantage of this removal to inspect the sunroof, which was still making noise.
It was driving me crazy.
It felt more like a wooden trawler than a car.
Headliner removal is straight forward.
Patience and calm is the key to do it right.
In 1h, it was done:
And I decided to check all the bolt that tight the sunroof frame to the car and surprise: all were loose
Here the official VW workshop manual for the torque of each bolts (3 types, 3 torque level):
I removed one by one screw and put loctite (medium blue on them) and tight them.
For the "biggest" one, "4" on the document, I did 1 turn and hafl before the torque wrench "click".
After road test, no more noise.
