I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the upgraded sway bars and it completely bricked the module.

I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now. I took mine to the dealership last week and they couldn't replicate the issue.

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now.

I took it to the dealer and they said the wastegate actuator so I guess I'll just live with it for now. Have you checked the fluid levels? That's usually the first sign of trouble.
