Thanks all for your help, but I think my problem is solved. I've only had my F a few weeks and am still learning about it. Looking at the photo I attached at the top, now that its blown up, it looks like the hole in the rectangular piece isn't to hold a clip, the edges look broken. So I looked closer under an strong light and magnifying glass. Something definitely broken off.
I suspect that there should be a tongue attached that is broken off & that piece locates under the centre tunnel console. I'll have a go at making some kind of fixing to hold it in & if that isn't successful, a replacement fascia is on the cards.
Cheers
Scotty.
