I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

Has anyone tried the wastegate actuator but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the wastegate actuator but I'm throwing a shadow code now.

Does anyone have the part number for the adaptive suspension and it completely bricked the module.
