It looks as though the air riveter used on the pop rivets removed the protective coating across most of the face of the aluminium rivet (it still seems to be visible on the edges). The riveter possibly had a worn nose piece on it, but the application of seam sealer should completely alleviate any corrosion issue from where the coating was removed.

As the SIB says, the structural integrity is due to the adhesive anyway, the rivets are there to tightly hold the assembly in place while the adhesive cures, the rivet corrosion without the seam sealer for surface protection would be more of a cosmetic issue in the future.

Ah, galvanic corrosion. The gift that keeps on giving.

Shouldn’t be a galvanic corrosion issue, as the unprotected / bare metal area doesn’t bridge between dissimilar metals, just exposed aluminium corrosion without the protective coating.

Ah, I misunderstood where the resin was missing, I thought it was the interior mating surfaces. Gotcha.

So the takeaway is:

1) good news: the defect was cosmetic and there's no long term issues.

2) bad news: buyers had to suffer a stop sale for a cosmetic issue rather than a later recall. BMW could have let you have your car and fixed it later.

I get why BMW didn't do that, it is much cheaper and does less PR damage than issuing a recall. Still, it's gotta sting.

Although this doesn't list the G42/G87 it describes the exact same issue for the G20 which we know were also affected by the stop sale. I suspect they may update this SIB in a future revision to include those models. Another possibility is the issue was isolated enough with those models that any cars that were affected are already being addressed.

Thanks much for sharing!

Agree with you that it's great news the issue was not structural or mechanical in nature.

However, I would have rather had the repair done at the factory or VPC than at the local dealer. By now, the techs at VPC have gained sufficient enough experience in this particular task to, hopefully, do a great job. Whereas, your local dealer techs (as good as they may be) may require additional training.

They're just applying seam sealer to the rivet heads, fairly straightforward. The worst that can happen is they are sloppy in its application but honestly who cares, no one will ever see it.

While they may/will do some, the VPC does not have the tech manpower to stop their normal course of business to address each car in need the "fix" proposed (and likewise, the factory cant stop and put completed cars back on the assembly line to do the same). In many cases, local dealerships will be the only means to have the work done.

Stop sale was cleared today and looks like it arrives later next week which is unfortunate as I will be out of town..

Normally I can agree with you, however in this particular case, when the issue can be fixed by this guy then just about any monkey can do the job. (No offense to this guy or monkeys)
