My pano roof makes a creeking noise when closing. it happens when it lifts to vent at the back of the glass. My Cayenne is a 2012. It is a minor issue, but does anyone know where and what type of lube to use to quiet it down?

 

I'm sure it's not the right stuff, but I use regular spraying oil, and then dab the excess with an absorbent cloth.

Cheers,
