Question:
Tried to disassemble the original VAG MQB49 5C key and read key data to add a spare key using Xhorse Key Tool MIDI, the MIDI does have this option, but it says function not supported and needs VVDI Programmer to read it first. Any clue?

The VVDI Programmer here refers to Xhorse Multi Prog.
