Just thought I would share that I have replaced the rear seal on the opener of the panoramic sunroof today. It had shrunk over time and this left an 8-10mm open gap each side of the panel.

It's really easy to change and isn't bonded on, the profile of the rubber just fits into the plastic molding of the glass panel, it took about 10 minutes to change with a set or steps to get up there.
Part no. Of the rubber is 54107493155 and it's slightly over sized so you just have to trim it down.

I didn't take any pics before but have a couple of it fitted.

I have seen other posts where this was cited as a source of wind noise. BMW will replace under warranty if the car is still covered

Funny that - mine had shrunk by the same amount. Dealer ordered and installed new one a couple of months back. Seemed to lessen some whistling noise I was getting from omni-direction :-)

got me curious, and ran out to check my car.
Did'nt understand and looked fine on the drivers side, then checked out the passenger side, wow- Here is your "BEFORE".....

Thanks for posting this!

The thread that covers it is called

Wind noise / whistle on 2022 X3 M40i

Can't seem to link it on my phone sorry.

Mine didn't give me any wind noise or whistle but I was concerned about the extra water ingress when it rained or the car was washed.
The gaps on mine were similar if not slightly bigger than the ones on kevinkays car.

The thread might be useful to a few people.

Thats a great document.

On a side not any know where the rear drains exit? I'm Guessing its behind the bumper looking at the doc.

Appointment made.

For DIYer's:

Indeed a great document. I love it when a company has rigid process. This caught my eye:

An extra screw may have
fallen into the track during production. The screw is not
missing from any location.

-- So they have enough "loose screws" on production that it makes it into an advisory :-|

My plan is to drive in, show my SA and if any question arises - lets walk over to the showroom or new car lot and compare rubber.

Just had mine replaced at the dealer - under warrantee.
Drove in and showed the service adviser the gap, she made me a service appointment. unfortunately they did not pre-order the part so took 2 days to get the new seal once the tech looked it over. I watched the tech put it on - took about 20 min and tech was using a mirror (like a dental mirror) and maybe a screwdriver. Looked like he was verifying it was properly attaching with the mirror.

hey All,, just replaced mine front seal but the rubber is not flush nowwhen i push it in than it is flush the sides no gap anymore or is it normal that the rubber is a bit above the glas panel?

thank you all greetz from rotterdam

mine was replaced under warranty at 7 months after picking it up from the factory.

Mine was replaced under warrantee because I asked with the knowledge of this post - THANKS
I also asked it be "adjusted" as I thought the center of the movable glass was a bit higher in the center where it met with the back glass. The service adviser didn't really agree with me but the tech did. They tried to adjust but at max. adjustment they could not get it flush, determined the back glass was "defective" and so replaced the rear glass panel. Took a week, but I had a loner and always happy to get new parts!

Thanks for reposting this! I just started to hear some noise from the sunroof, it’s worse driving into the wind. Even though it’s a MY23, I’m going to have it checked out at my next service appt.

I’ve been through hurricanes that make less wind noise than my sunroof right now. It’s shrunk about a half inch so I scrunched it over to one side and have a piece of painters tape covering the hole. It’s working for now until my next service appointment but ugly as anything.

Had mine checked during recent service, and it had shrunk a little both sides, MY2022, dealer ordered and replaced, picked up this morning and had a couple of hours drive. The cabin is quiet, but just had a little whistling now and again at motorway speeds which was the reason I had them check, can confirm nice and quiet again now.

When I finally order my X3 I just might step up to an X3 M just to option out of the damn sunroof. I much prefer a slick top. I'd pay extra not to have a sunroof. Such a shame the X3 M40i forces the glass roof upon you.

I would have said the same thing about a sunroof deletion but after I got the pano roof for the first time I’ll never go back. Now if they had a full sheet, fixed pane of glass that would be even better. Couldn’t care less about opening the sunroof.

Mine is a Sept 2022 pickup, 2023 Model.

I have had this replaced 3 times under warranty.
