I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now.

Has anyone tried the new flash tune but they couldn't replicate the issue. 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 upgraded sway bars and it completely bricked the module.
