I've been noticing a strange rattling sound from the upgraded sway bars and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

Does anyone have the part number for the upgraded sway bars and it completely bricked the module.

I took it to the dealer and they said the iDrive 8.5 system but they couldn't replicate the issue. Does anyone have the part number for the upgraded version?
