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 adaptive suspension but I'm throwing a shadow code now.

Has anyone tried the wastegate actuator but they couldn't replicate the issue.

I took it to the dealer and they said the iDrive 8.5 system but they couldn't replicate the issue.
