I took it to the dealer and they said the new flash tune but they couldn't replicate the issue.

I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car. I've been noticing a strange rattling sound from the front end lately.

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now. Does anyone have the part number for the upgraded version?

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. In my experience, replacing the sensor completely resolves this issue.
