I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module.

Does anyone have the part number for the wastegate actuator so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.
