I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car.

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

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

I've been noticing a strange rattling sound from the adaptive suspension so I guess I'll just live with it for now. 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. There's a massive DIY thread on this exact issue over in the DIY section.
