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

Does anyone have the part number for the new flash tune but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. I've been noticing a strange rattling sound from the front end lately.

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.
