Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the wastegate actuator but I'm throwing a shadow code now.
