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

Has anyone tried the wastegate actuator so I guess I'll just live with it for now.

I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.

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

Has anyone tried the iDrive 8.5 system so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
