Sagging headliner in a C4 Grand Picasso.

[habo]

The headliner of my Citroën G. Picasso has sagged. I tried fixing it with spray adhesive and a syringe needle by poking holes and injecting the glue, but it seems that the foam of the fabric has deteriorated, and it won't stick. The only solution now is to remove the roof panel, buy new fabric, and glue it on. What discourages me is the plastic trim that needs to be removed, as I'm worried I might break a clip, and also the airbags around the area, which I believe there are 6. Has anyone done this themselves who could offer some advice?

The best thing I'd advise is NOT to put any glue in there in case it needs to come off later, which will make it impossible. The best thing to use is double-sided tape. Depending on where it is sagging, you may be able to put a bit of tape in through the roof mounted console access or the courtesy light unit at the rear, or from the tailgate.

Basically it's one large unit that slides in and is held by the grab handles and the pillar trims etc and depends of whether you have a sunroof of course as to the complexity.
