Hmmmm

Someone has modified my L322 headlining!

I’d take the screw out for now a cover the hole with duct tape until you decide on a permanent fix.

my previous l322 started to go there. and I reattached it with a few safety pins, to stop it getting 'a flap-on' at speed... as that kills the headlining. basically, the foam between has turned to goo, and its starting to delaminate. on a second car I drive, this happened, (Bmw) and I had a guy replace the whole headlining, material and pillar posts, and sunroof panel. he did a great job, and I collected it all, and just need to fit it in. he does range rovers all the time, often ready-made on exchange. based in Somerset.
I sold my old l322, with a tatty headlining... but the Bmw, collapsed, and got a 'flap-on'. the old foam behind, was like sticky cake!
