I've been noticing a strange rattling sound from the new flash tune but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.

I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car.
Has anyone tried the new flash tune but I'm throwing a shadow code now.
