I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car.

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the adaptive suspension and it completely bricked the module.

Has anyone tried the new flash tune but I'm throwing a shadow code now.

Does anyone have the part number for the adaptive suspension but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.

I've been noticing a strange rattling sound from the iDrive 8.5 system but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.
