R3 Headliner Sunroof Aperture Plastic Trim Problem

I've just replaced the headling material on my 200 iS.

When I tried to refit the sunroof aperture trim, it appears to have shrunk. 😱

After a bit of a faff, I managed to fit all 6 clips, although one subsequently pulled away from the headliner board. 🙄

Unfortunately, it's clearly not gripping at the sides. Does anyone know what I'm doing wrong?

Was the original headlining material wrapped over the edges of the aperture? (Effectively making the hole smaller)

I couldn't remember that, so I did wonder.......then I realised that there was no evidence of old glue or foam in the upper surface!

Hi all. After a lousy past 8 months and my energy levels apparently beginning to improve (🤞), I've started to look at this problem again.

I've had to glue two of the clips to the headlining to keep them in position.

Has anyone experienced similar problems and come up with a neat, strong and lasting solution?

And ideas will be gratefully received, as until I can put it back in the car, I can't really start rebuilding the interior. Thanks.

I think I have found a solution, after looking at the headlining in my 25 Impression S3.

The clips actually retain the plastic trim to the sunroof tray, not to the headlining material. The material and backing board is merely sandwiched between the two.

I hope that helps :)

Blimey, I would never have thought of that. I will have a look.

Thank you so much for taking the trouble to investigate.

Sir, you are an absolute Genius! I've just had a look and sure enough, there are marks both on the leading and trailing edges of the sunroof frame.

I can not make a proper start on putting it all back together.

Once again, thank you so much for solving the mystery!

Oh dear, the 218iS is still in bits. My ongoing fatigue has hampered progress, although I had managed to get the headlining refitted along with various fittings.

I didn't notice it initially, but unfortunately there's a concave gap either side, which clearly isn't right. It certainly isn't present either on my Brother's 25 or a former colleague's 218 i!

The actual shade is clearly concave from below, as can be seen in the photo.

When I was cleaning all the old glue and disintegrated foam off the panel, most of the time was spent kneeling down with it laid flat on a hard floor. Surely, I couldn't have created the bow in it..........could I?

It's now out of the car again, hopefully pending a solution. Most frustrating.

As always, any observations or advice would be appreciated!

PS I assume I'm correct in thinking that the two spring loaded guides are meant to fit inthe uppermost groove?

I dunno, that concave gap looks like something one would find in a lot of cars, build quality etc.
