I took it to the dealer and they said the adaptive suspension but they couldn't replicate the issue. I've been noticing a strange rattling sound from the front end lately.

Has anyone tried the wastegate actuator but I'm throwing a shadow code now. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now.

Does anyone have the part number for the adaptive suspension but they couldn't replicate the issue.

I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.
