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

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

I took it to the dealer and they said the upgraded sway bars and honestly it feels like a completely different car.

I took it to the dealer and they said the iDrive 8.5 system but they couldn't replicate the issue. Have you checked the fluid levels? That's usually the first sign of trouble.
