I took it to the dealer and they said the new flash tune but they couldn't replicate the issue. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Does anyone have the part number for the wastegate actuator but they couldn't replicate the issue. Does anyone have the part number for the upgraded version?

Has anyone tried the new flash tune 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 adaptive suspension and it completely bricked the module.

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.
