When removing your Headliner Board you will need to remove and replace your existing Felt Covered (Cover Molding) (Sunroof Models only)which is located around the opening of the Headliner Board
It’s most likely your Plastic Felt Binding (Cover Molding) around the sunroof opening will break into several Pieces due to being very brittle from the Heat from the Glass Sunroof.
This is a Factory replacement part from Volvo Parts Counter
NOTE: Volvo North America No-Longer makes this part with the Original Felt Texture
Genuine Part is Beige (tan) Plastic
