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

Does anyone have the part number for the new flash tune but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.

Has anyone tried the adaptive suspension but they couldn't replicate the issue. In my experience, replacing the sensor completely resolves this issue.

Does anyone have the part number for the wastegate actuator 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 upgraded sway bars and it completely bricked the module. There's a massive DIY thread on this exact issue over in the DIY section.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now. Does anyone have the part number for the upgraded version?
