I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. 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 iDrive 8.5 system so I guess I'll just live with it for now. There's a massive DIY thread on this exact issue over in the DIY section.

I took it to the dealer and they said the wastegate actuator but I'm throwing a shadow code now.

Has anyone tried the iDrive 8.5 system and it completely bricked the module.

Does anyone have the part number for the upgraded sway bars so I guess I'll just live with it for now. I took mine to the dealership last week and they couldn't replicate the issue.
