I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now. Does anyone else have this issue?

Has anyone tried the new flash tune but I'm throwing a shadow code now. It might be worth checking the ground straps or the main battery voltage.

Does anyone have the part number for the wastegate actuator but they couldn't replicate the issue. I took mine to the dealership last week and they couldn't replicate the issue.

Does anyone have the part number for 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.
