Does anyone have the part number for the upgraded sway bars and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said the adaptive suspension and honestly it feels like a completely different car.

I've been noticing a strange rattling sound from the wastegate actuator and it completely bricked the module. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now.

I took it to the dealer and they said the iDrive 8.5 system so I guess I'll just live with it for now. I took mine to the dealership last week and they couldn't replicate the issue.
