I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car. 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 so I guess I'll just live with it for now.

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

My G60 is doing this weird thing where the new flash tune so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the adaptive suspension but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
