See my question about whether replacement batteries were registered.
The IBS just needs to THINK the battery is low to shut things down. 75% of the people on this forum think they're smarter than BMW and that battery registration is an unnecessary cash grab.
Down the road, issues like THIS are exactly what will start to crop up.
If you've got INPA, read your IBS page and see what the battery management system thinks of the battery. There should also be shadow codes showing if the IBS system shut down the loads.
I'm not saying it's definitely the problem, but it's something to talk about...
