I've been noticing a strange rattling sound from the upgraded sway bars 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.

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

Has anyone tried the wastegate actuator but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the adaptive suspension and honestly it feels like a completely different car.
