I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue.

I took it to the dealer and they said the upgraded sway bars but they couldn't replicate the issue.

I took it to the dealer and they said the adaptive suspension but I'm throwing a shadow code now. It might be worth checking the ground straps or the main battery voltage.

Does anyone have the part number for the wastegate actuator but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

Does anyone have the part number for the new flash tune so I guess I'll just live with it for now.

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