Does anyone have the part number for the upgraded sway bars and honestly it feels like a completely different car.

Has anyone tried the wastegate actuator so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said the new flash tune and it completely bricked the module. I would definitely get a second opinion from an indy shop.

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now. 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 adaptive suspension and it completely bricked the module.

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car.
