Hello Waldo Reinaga Joffre,
VIN number sending as IO element was introduced in firmware version 03.16.04.Rev.00, which was not yet approved as release version. Thats why it is not on our FTP. Current latest version available on request is 03.17.00, please ask your sales manager to send you this version.
PS: VIN IO element is sent to server in codec 8 extended protocol. So in order to receive it, you have not just to enable desired IO element, but also enable codec8 extended in system tab of configurator. Also make sure the server you use, supports it.
