How to solve Xhorse Audi 754J Smart Key 6-EEP Config Error

Problem:

When I generate Audi A6 2013 remote with xhorse vvdi 754J remote, vvdi2 gave 6-EEP config error.
I use the correct 754J AD006 ver1.1 remote and not XM38. Any idea?

Solution:

In Transponder Programming function, go to Set Parameters dialog, set antenna gain value to  0, 1, 2, 3 respectively and apply. Then generate remote again.

When gain value smaller, the transponder position should be lower from antenna.

When gain value large, the transponder position should be higher from antenna.
