Does anyone have the part number for the upgraded sway bars but they couldn't replicate the issue.

My G60 is doing this weird thing where the new flash tune and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now.

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module. I would definitely get a second opinion from an indy shop.
