Problem: The Xhorse VVDI2 was unable to program BMW motorcycle 8A key learn. It always said:
"Reading data failed! Attention: make dealer key require unlock X_SLZ/X_EW first! Warning: coding was lost!!!"

And it was interrupted while trying to unlock X_SLZ/X_EWS:
"Target unit doesn't response, or response error command! Error:7F 10 12"

What's the problem? Please advice.

Solution
In this case, it's suggested to do coding with VVDI BMW BIMTool Pro Tool again. Then the problem will be solved.
