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

I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. In my experience, replacing the sensor completely resolves this issue.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the wastegate actuator so I guess I'll just live with it for now. I've been noticing a strange rattling sound from the front end lately.
