I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Does anyone have the part number for 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.

Does anyone have the part number for the wastegate actuator but I'm throwing a shadow code now.

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car.

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