The edge of the rear headlining on the right side next to the upper tailgate has started drooping. Has anyone got a suitable fix before I spend ££££ please? 2021 3.0 P400 Vogue

Never heard of this problem on a FFRR. Maybe it has been causes by a previous owner/vendor steam cleaning

Relatively simple fix actually. I took a closer look and found the D-pillar trim wasn't clipped on properly (not sure if it ever was as one of the plastic fixings was bent). I straightened the fixing, reattached the trim and it seems to have solved it.  2021 3.0 P400 Vogue

There are clips, fixed to the roof, that the headlining clips onto. Maybe one of these has come away. I know because the one in the centre has done this on mine (following install by previous owner of wiring for wireless headsets). Never got round to fixing it. .

As above, the headlining next to the rear pillar is held in place by the rear pillar trim.

Same as Joe90 for mine.
Dan (Duckworths) sorted me a new clip.
In the centre its two parts - a metal U shaped piece with teeth and a plastic T shaped piece which attaches to the headlining. It really is a two minute job. I removed the rubber tailgate seal first, then fit the new clip and pressed the headlining into place. The rubber tailgate seal then covers the edge of the headlining.

I may need a couple of those clips in that case. Do you have a part number please?

I'll send my Dad to Duckworth's as he's only ten miles from Market Rasen.  2021 3.0 P400 Vogue
