Just a hypothesis - maybe at lower temp, the movable roof panel shrinks just enough that it is no longer so tight squeezed against the fixed glass portion, allowing vibration/movement which results in rubbing between the seal pieces? as Tex94 mentioned, one member found lubrication took care of the rattling.

I agree with your hypothesis. I believe changes in temperature causes the part(s) to expand or contract producing a rattle when the part(s) has contracted.

Great.. now I'm going to notice this rattle.

So far I haven't noticed it in my 2019.. but then again I wasn't paying attention to it. I'm crossing my fingers they fixed it. Reading about your issue it does sound like the contraction of materials when cold is your issue. Don't know if it's possible to add padding to the trouble areas, under the molding. Possibly just a little bit of thin double sided foam tape is needed under the trim/rubber. (note I haven't looked to see if this is possible and just "thinking out loud")

It's been fluctuating between 40-65F this week and haven't noticed yet on my '19. Though I only have 600 miles for now

It’s a noticeable noise that sounds like something is loose. When or if it does it, you’ll know it without straining to listen.

135 miles on mine and haven't noticed it. I think I would noticed a loose clicking if it's that pronounced. Possibly they fixed it for the '19 models.,

Arrhhh... It that ever happens, I would just install a pair of 12" subs pair with a 1600 W amp in the trunk, and hook the ASD to them to drown out the noise!

I was finally able to test my theory of the cold, dry air causing the glass to shrink enough to rattle. It appears this may be the cause. I drove this morning (cold but still damp) and no rattle at all. Drove this afternoon (cold and dry) and the rattle was back. Applied a generous helping of Mothers Protectant around the moving glass and all of the rubber pieces around the opening and then took it for another drive. No rattles! Very pleased with the result (or will be as long as I don’t need to apply it more than once a month or so).

Good to hear you narrowed the issue down. Where I'm located it's damp so might not hear mine for a while.

Good to know you found the solution. I think you are the 2nd one whom reported lubrication worked.

I just got my x3 back from the dealer after taking it in for the rattling pano roof. I’m thrilled to report they fixed it. I used a different dealer for this car and they did a much more thorough job at fixing the problem. They replaced both the moving portion of the seal and then replaced the fixed roof seal. Rattle is finally gone. Here is a screen shot of the work order.

Thanks so much for posting this!! I'm sending it to my dealer. They had my 2019 m40i for 5 days and couldn't replicate the rattle.

My month old 2019 X3 has the same sunroof rattle. And it seems the rattle/noise is related with humidity of out side sunroof rubber seal. This is because if I do a car wash, the noise is gone for the day but it comes back next day once all humidity is dried out.
My sunroof rattle started 2 days after I picked up a new car from my dealer. And I spent a lot of time to pin point the area of the noise. It seems the noise comes from rear passenger side fixed glass of panoramic sunroof. If I apply some pressure to the center rear glass, the noise is a little diminished or it makes slightly different noise.

Since I found where and what rattles, I visited dealer and explained everything what I and this forum members found. On the first day, they called me they were unable to reproduce the noise/rattle. Next day, I visited the dealer again and I drove with one of their engineer. The engineer identified the noise, so I left my car again. At the end of the day, dealer called me and they refused the fix. They said they tried 4 of their 2019 X3 loaners and ALL OF THEM have the same noise. So it is "characteristics" of 2019 X3 and BMW won't authorize the fix unless they have some service bulletin. I got completely speechless for a while.
I also showed them the screenshot of work order bmtespar posted. And told them another BMW dealer fixed it already. The service adviser told me, they can't identify the work order since it doesn't have model year or VIN number.

I complained again why you can't fix it since you know where and what rattles and the service adviser keeps repeating, "I understand.. I'm on your side.. it's unfortunate but it is a characteristic of the car".
After unhappy experience from my BMW dealer, I ordered a rubber protection product and applied it to outside of rubber seal as forum members here recommended. Now the noise is gone at least for two days until today. I hope this lubrication lasts long.

What fucking bullshit. There is more than enough identifying detail in that picture for him to have contacted that dealer and gotten whatever information he needed. What poor service!

European Audi Q5's have had a notorious reputation for Panoramic roof rattles over the last 2 or 3 years - so much so that some dealerships have even resorted to offering a separate Pano roof servicing schedule.
I strongly suspect that the BMW problem is a similar one, where many of the internal mechanical components simply need re-greasing on a regular basis (and perhaps more often if you live in a warmer / sunnier climate). Aware of several cases where the entire Pano roof units has been completely removed and replaced under warranty, (on this side of the pond at least), I'm afraid there doesn't appear to be a universal long-term solution yet available.

I suspect a rattling panoramic roof is the result of years of exploding sunroofs bmw had in years past. It was surmised that the sunroofs were installed with too much pressure and could explode under conditions of climate change. So now we have sun roofs with more tolerance to avoid explosions but rattle like crazy. Thanks, BMW.

I just purchased a 2019 X3 service loaner with 4K miles on it and I want to report to the group that I have the exact same rattle that everyone’s taking about. It’s clearly coming from the passenger side. I am leaning pano but not positive. Major sigh! I also have a rattle on the drivers side for a nice enjoyable stereo affect. Come on BMW! Thanks for the $50K rattle trap.

We’ll see if BMW Motorwerks can diagnose and resolve both rattles. Car goes in on July 15th. I will report back (in detail) as to exactly what gets fixed or doesn’t.

Right now I am literally embarrassed to have passengers. Funny how you don’t notice these things on the test drive with the sales person talking incessantly.
