I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car.

Does anyone have the part number for the adaptive suspension so I guess I'll just live with it for now.

Has anyone tried the adaptive suspension but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the iDrive 8.5 system so I guess I'll just live with it for now.
