Has anyone tried the wastegate actuator but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the adaptive suspension 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.

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car.
