This is my back window trim on the passenger side. I think this trim may be cosmetic, but I still want to fix it. Any experiences?
I need to be more consistent in keeping my car cover on.

Why fix? free weight reduction? :lol:

But good question, I have the same exact issue. Is it purely cosmetic or does it have some mechanical function?
Cosmetic. The glass is sealed against water intrusion by itself.
That's the rubber sealant from the rear window .
And all the rubber from our cars need maintenance on time...and before it's too late .
That rubber from OP is completely dried out and will break further , a replacement is required in the situation.

Again...Rubber requires maintenance !

I figured it was. Should be easy to fix. It's taking itself off already. lol
How much is the part?

The windshield trim is known to crack prematurely. I've changed two of them so far and it's one of the easier installs. The dealer will remove the windshield to install it. You don't need to. The part is cheap too.
Cheap and easy 15 minute DIY job.

Rear trim seal: 51317119713

Either trim only costs about $30 for new OEM.

Nothing here. It's pretty self explanatory. Peel out the old one, push in the new one. No clips or tabs to break.

Cool - I'll give it a shot.

Deansbimmer is the expert but I always though that rubber around the front roof and rear surround was "glued" on and that "glue" is not fun to try and remove before putting the new one on.
There will be some residue but nothing some adhesive remover won't nix in a jiffy.

Yeah I can tell by trying to pull on it a bit that's going to require a little more elbow grease. I'll report back post-install.

Mine came off super easy. Cleaned the minor amount of residue with some denatured alcohol.
i touched mine at a gas station when i noticed a crack and the pic in the original post was the result. mine is voluntarily removing itself.
I bought this molding for 45 and had a local shop install it for 50. Took about 20 minutes or so.
was looking for this info too, thanks!
I'd recommend being extra careful to line it up properly first before removing the backing on the tape for final install. If it's a little off center the top corners (on the front windshield) won't sit exactly right. I did my m3 first and it's not perfect. Did my moms car after and got it just right. Looks a lot better on hers.

Dug up my old password to say thanks for this info, helped me greatly. Unfortunately the parts are no longer $30 in 2025 :D

I ran into some major difficulties doing mine. While trying to get one corner of the new trim metal slot to fit over the windshield edge, I cracked the windshield. My advice is to let a body shop Professional do the windshield trim replacement. Preferably someone with experience. It's not as simple as it sounds. Good luck to whoever finds this now or in the future.
