I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the new flash tune and it completely bricked the module. There's a massive DIY thread on this exact issue over in the DIY section.

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