I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. I would definitely get a second opinion from an indy shop.

Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. Does anyone else have this issue?

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

I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?
