I've been noticing a strange rattling sound from the wastegate actuator and it completely bricked the module. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the upgraded sway bars so I guess I'll just live with it for now.

Does anyone have the part number for the new flash tune but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the iDrive 8.5 system so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
