Good question, I think I'd have mine done if there were a guarantee that it'd be perfect with no squeeks, rattles etc.... but can they guarantee this?

I'm curious about your work parking location. You stated it's a parking deck which piqued my curiosity.

Is it always the same stall?

Is it sloped (ie: on a level change ramp)?

Are the stalls perpendicular or angled?

M2CS roof replacement isn't something to take lightly. Is Global Imports your center?

[robopp]

I'd tell them to buy it back. Zero chance I'd want them replacing the structural roof and zero chance I'd want to keep the car the way it is.

[gemini.m3]

sorry man, I'd push to get them to buy it back -- I'm just thinking of all the potential issues you could have down the road in trade off for a cosmetic issue - replacing the rear and front windows is no joke - your car is going to be down for months likely

I'm so sorry this has happened to you, I'm still curious what the cause was.

[mchart]

I'd ask them if it's cosmetic only, and if it won't get worse. If it's just cosmetic and it doesn't get worse - I wouldn't risk a replacement unless I knew EXACTLY how the body shop is going about doing it.

[Tornado1M]

I'm so sorry to hear about this! I can't imagine how frustrating this must be.

Since it is cosmetic and not anything more, I would go the route of getting compensated if you wish to keep the car......I certainly would not want to deal with it going through major surgery! You just don't know the other issues that may arise down the road.

Take the money if it's an option and it should be in the neighborhood of 10% of the price you paid in my opinion. $1-3K is not going to work!!! Don't settle for something low like that.

If that's all they offer, I'd sell it back to the dealership!

Good luck and keep us posted!

Yikes 👀

[Golden3ye]

Am I missing something. Seems like getting it swapped is a no brainer.

[gemini.m3]

He's taking it much easier than I would. I would absolutely NOT settle for anything but a buy back to be honest even being compensated for it wouldn't do it for me. This is a brand new LIMITED edition car that can't be replicated and isn't in production anymore. I would ask them for VERY specific technical details on how they would even approach replacing the roof and if I wasn't content, which I don't think I would be, I would start e-mailing/contacting BMW of USA and turning this into a big deal. If this was anything but the roof it would be acceptable to be repairable.

This is absolutely a shit situation and for me getting out of the car albeit disappointing would be the only solution. This isn't some used car purchase.

Please elaborate.

At least in Spring 2018, BMW offered a CFRP roof for the F22 2er, F87 M2, F87 M2 LCI and F87 M2C as part of their M Performance Parts portfolio (BMW part # 41 31 2460277). Classic 'on top' CF roof (keeping the roof drip rail with flaps and roof rack anchorage points + roof bow) - not the M2 CS only 'integrated' sandwich-structured composite CF roof (the M2 CS does not feature roof drip rail with flaps and roof rack anchorage points and also does not feature a roof bow). For ordering and installation, customers were referred to their BMW M dealers (though I can imagine that most would outsource this type of uncommon operation, preferring to steer clear from screwing up a car - this ain't no 'plug & play' type of operation).

Excerpt of a Spring 2018 interview with BMW M (see here):

The vehicle on display is the same car that was revealed last weekend at the Hockenheim Ring. The talk discussed all the questions we had and a lot more. You will read all the details below.

• Can or will all of the M performance parts be installed by the dealer? Cough, including the roof, cough...
BL: All aftersales parts are being installed at the dealer. Every single part!!!! The dealers will be handed extensive manuals on how to deal with it. The installation will be done as we have seen before in videos online. The window screens are removed, the welds are being drilled and the new roof is put into place. The dealer will have to do it. If they don’t want to do it, it means you should go to another dealer who does want to do it. For the U.S. market it means that all parts are either fitted at the port on new cars, or at the dealer when you have a 2nd hand M2C, M2 (LCI), M240i, or a normal 2-Series Coupe.

• Does BMW want to sell plenty or only a few MPP CF roofs?
BL: I cannot comment on sales numbers.

• What about certification of the newly fitted parts?
MR: In certain countries you would need to go to the local technical check/registration office and make sure your car is checked by them after you have installed the parts. Especially when you fit a carbon roof, carbon bonnet, carbon side fenders and carbon trunk. Certain countries might require you to have this mentioned in the paperwork. Unknown which countries, this is totally specific to your situation. I will not have this in Czech Republic. Frank van Meel pointed me on this and definitely check it locally. U.S. will be a lot easier when you order it via the port since then it is all included in the handover and type approval of the vehicle!

Required: new CFRP roof, new front window, new rear window, materials + labor.

[mchart]

He's saying a normal body shop likely isn't qualified to do the work. If the work is even possible, because it's not just slapping on the non-structural CF panel. The structural roof on our car is bonded on with adhesive, and some other procedures unknown to most people if you didn't see it done on the factory floor.

I'd be very curious to see the documentation BMW sends the body shop on how replacement is done, to see if it's even possible without the car being declared totaled due to safety concerns.

Maybe it is just as easy as slapping a new panel on and applying auto seam sealer, but I really doubt it. If it is, great news for all of us as we know it's an easy fix.

I've seen the youtube videos of the installation you refer to above and none of them did it anywhere near my own level of comfort. They were performed in dirty environments with unknown solvents and temperature using who knows what adhesive.
In the world I am familiar with, which is aviation and space we do these dissimilar material bondings in clean room environments at very specific temperatures with very thorough procedures and check lists.
Yeah sure, your car is not an airplane or spacecraft, this is true, but the same principles apply and I for one have zero interest in letting some kid whose training consisted of basic metal fabrication and wet sanding install my CF roof. This is leaving out the question of exactly how they are going to successfully and fully debond the old roof pieces and clean the surfaces for the new one.
I am sure it can be done, just about anything can be done, but not on anything I own.

According to BMW, also a new front & rear window are required for a CF roof install.

And afterwards the interior will smell 'some kind of glue' for some time.

It's sheer impossible to beat the precision of a KUKA robot at the BMW factory. This is an expensive operation (materials + labor) requiring experienced hands and dedication for achieving a near-perfect result (which also includes an immaculately preserved interior, everything properly reconnected, no creaks and zero niggles or gremlins in the future).

Sorry to hear. I agreed with some post that asking BMW to buy back if possible because this is a limited run and not a mass production. It's not going to cost a few grands for sure so they might willing to compensate to avoid PR nightmare

I would email the CEO of bmw to file a complaint to start. His email can be found on google.

We need to stick together because our CS are limited and if it happen to anyone of us then we should start a class action lawsuit

Good point. I'd be very curious what the root cause is here because if this isn't a one off that's going to be a nightmare for current owners and potential buyers.

I trust that BMW will properly take care of the situation. The car was inspected and rapidly the proposal was made to replace the M2 CS CF roof under warranty: this reflects that BMW is prepared to walk the extra mile for the unfortunate customer. And as far as we know, this is the only car (so far). So let's refrain from hostile 'torches & pitchforks' litigation talk.

[Fuji550i]

Of course BMW is going to fix it under warranty the car is literally brand new

Not being hostile but BMW has a pattern with long term issue with M car such as subframe issue with E46 M3. Rod bearing etc. I had to deal with E46 subframe after the limited time warranty expired as a long term owner. I know this is one case only but once warranty expires, we will be stuck with the problem to deal with if this become a pattern.

[g.lor]

After some thought and reading everyone's input I'm leaning towards trying to get BMW to buy back. It just makes me sick to the stomach having to send my brand new car in for major body work after just 1500 miles. I hope this is an isolated issue and no one else has to go through this. I'll keep you guys posted with any new developments. Thanks for the support!!

I'd wait to see what the process is for replacement. If there is a clearly defined process that seems fine i'd just let them fix it. If the fix is crap, you can just lemon it / buy back at that point.

[AxM2CS]

On the other hand, if you can get the buyback that's a bird in hand that would be hard to refuse. You can most likely get another M2CS among the handful remaining in the US. Don't know if you have/wanted DCT vs. MT, or color options, but ultimately a brand new car would be a good outcome.

Let us know how it goes. Ideally they do this and provide an explanation- might be good to just mention there are enthusiasts this car went to that are aware of this scenario and how BMW NA handles it will resonate with that group.

If they push back, I would quite simply ask them how they would plan to replace the roof considering it’s a structural element of the car.

I’d mention this is highly invasive surgery and that you’re more concerned (as they should be) about short and long term safety if the structure of a brand new car is compromised. Sounds silly but does this body shop or service center even know how the roof is made? What kind of technical documentation would they be getting from BMW for repair? Do they just have other roofs with that pattern laying around for a car that’s out of production ?BMW needs to own up to this, I think if you push back this hard they might try to press you to prove it didn’t happen while in your care but I don’t see with no scuffs or other identifiers them proving that

Just remember you’ll get more out of them with sugar than salt, be nice

Remember that, unlike other BMW M CF roofs, the M2 CS CF roof is a structurally integrated part of the car. The operation involves some invasive surgery.

As usual, very conscientious advice here, Artemis

To supplement your install videos, here's a PDF of the official instructions for laying down an M Performance carbon fiber roof, on the M2.

https://rparts-sites.s3.amazonaws.co...on%20instr.pdf

Not exactly a CS top but extrapolating from this general instructions, I believe, more or less, it gives you the gist of what the job entails.

No one asked for my 2 cents but I just want to say that if I was fortunate enough to have the pink slip to a CS, in an attempt to circumvent this inherent cosmetic defect, I would just do like Ferrari and Lambo and just paint my carbon fiber roof in the color of the body. - And right there, yet another one of life's perpetual problems is solved.

[F87EVO]

I might be wrong , but the procedure is a lot more different on the M2 CS (than the M2 Competition M performance roof)..Since its a structural part .. I would most probably leave it as it is.
