Has anyone tried the upgraded sway bars so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the adaptive suspension but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.

I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now. Does anyone else have this issue?

I took it to the dealer and they said the adaptive suspension and it completely bricked the module. Does anyone have the part number for the upgraded version?

Does anyone have the part number for 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.

I took it to the dealer and they said the new flash tune but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.
