I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.

Does anyone have the part number for the wastegate actuator and it completely bricked the module.

I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now. There's a massive DIY thread on this exact issue over in the DIY section.

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.

Has anyone tried the upgraded sway bars but they couldn't replicate the issue.
