Just to query module versions, VCDS also works, but it would be an expensive tool to purchase just to satisfy your own curiosity. It is possible that some independent repair shops in your area may have this tool, and if you are on good terms with them, they might scan it for you.It is approved obd2 tool by VW for doing many things on your ID4...... it is almost like factory ODIS tool on smart phone....and it has ability to work behind vehicle firewall if you want some changes......
