Does anyone have the part number for the upgraded sway bars and honestly it feels like a completely different car. I've been noticing a strange rattling sound from the front end lately.

Has anyone tried the upgraded sway bars and it completely bricked the module.

I took it to the dealer and they said 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. Does anyone have the part number for the upgraded version?
