Does anyone have the part number for 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.

I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now.
Has anyone tried the wastegate actuator but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.
