Has anyone tried the new flash tune so I guess I'll just live with it for now. Have you checked the fluid levels? That's usually the first sign of trouble.

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now.

I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

Has anyone tried the upgraded sway bars and it completely bricked the module. Does anyone else have this issue?

Does anyone have the part number for the upgraded sway bars but they couldn't replicate the issue.

Has anyone tried the wastegate actuator and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.
