Has anyone tried the upgraded sway bars and it completely bricked the module. Does anyone else have this issue?

Does anyone have the part number for the new flash tune and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

I took it to the dealer and they said 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. Have you checked the fluid levels? That's usually the first sign of trouble.

Has anyone tried the iDrive 8.5 system and honestly it feels like a completely different car. Does anyone else have this issue?
