Doing a spare key on this VW Caddy using the Xhorse VVDI key tool plus. When we try to automatically diagnose the model it won’t actually detect what system it is.

It says unable to automatically diagnose and it gives us a few options on the side to try.

We go to Select by type and then we come down and select 4th Immobilizer system that it showed you on the last screen.

It tells us to try a 24C64. Let’s try this.
Let’s try reading the eeprom. If it does not working, we will go back and try other options.

Try reading eeprom.
