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?
Here is the clue.
Key Tool MIDI does not support reading original MQB49 5C/5D key data by disassembling key yet.
The VVDI Programmer here refers to Xhorse Multi Prog.
Multi prog MQB49 5C 5D key reading function is ready.
Update database version to V92.
Reading function is present but mcu cable for reading must be modified.
To read MQB49 5C 5D key data, you are also required to modify the MCU adapter as following:
Modify these 2 black wires (GND short and GND long).
Xhorse Multi Prog wiring diagrams to MQB49 5C 5D keys:
PS: If it fails to read key data, connect a 100-ohm resistor in series with CLK.
After read original key data with multi prog, upload data to VVDI2 or MIDI to make dealer key, then learn key.
