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

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

I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. In my experience, replacing the sensor completely resolves this issue.

Has anyone tried the iDrive 8.5 system but they couldn't replicate the issue. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the upgraded sway bars so I guess I'll just live with it for now.

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now.
