I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now. There's a massive DIY thread on this exact issue over in the DIY section.

I've been noticing a strange rattling sound from the iDrive 8.5 system and it completely bricked the module.

I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
