Has anyone tried the iDrive 8.5 system and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the upgraded sway bars and it completely bricked the module.
