I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.

Does anyone have the part number for the new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the new flash tune and it completely bricked the module.

I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the adaptive suspension but they couldn't replicate the issue.

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.
