Does anyone have the part number for 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. Have you checked the fluid levels? That's usually the first sign of trouble.

Does anyone have the part number for the new flash tune but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module.
