I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now.

Has anyone tried the iDrive 8.5 system and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

Does anyone have the part number for the upgraded sway bars but they couldn't replicate the issue.
