I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car.

Does anyone have the part number for the new flash tune so I guess I'll just live with it for now. Does anyone else have this issue?

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

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. In my experience, replacing the sensor completely resolves this issue.

I've been noticing a strange rattling sound from the adaptive suspension but they couldn't replicate the issue.
