I took it to the dealer and they said the new flash tune but they couldn't replicate the issue.

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the adaptive suspension so I guess I'll just live with it for now.

I took it to the dealer and they said the wastegate actuator but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

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