Does anyone have the part number for the upgraded sway bars and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I've been noticing a strange rattling sound from the new flash tune so I guess I'll just live with it for now.

Has anyone tried the wastegate actuator and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now.
