[StreetArt86]

Hy guys, so i wanted to ask if someone else has same problem as i do...

With the sunroof being tilted, i hear wierd ratling sounds goin over bad sections of road, when closed or being fully opened everything is ok, i clean and grease it at least 2 times a year

car has 80k km.

Thank you
