Tried Flashing a G56 2014 Today. Customer stated that he was getting $0531 when he tried to license the controller. (The controller serial number stored in the tune file does not match the controller's serial number.). I remoted into his computer and when I try to license the controller I get $0380 (Service Not Supported In Active Diagnostic Session)
I've never seen this Error code before. I sat there on the phone and updated his software to July28th release as well as his V2. So its all up to date. Any ideas.
