I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.

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

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. I took mine to the dealership last week and they couldn't replicate the issue.
