Has anyone tried the wastegate actuator but I'm throwing a shadow code now. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the new flash tune and it completely bricked the module.

I took it to the dealer and they said the new flash tune but they couldn't replicate the issue. I've been noticing a strange rattling sound from the front end lately.

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

I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
