    Post ESP MK25A XT coding

    If you need to replace ESP control module from donor, or change options, you must insert your VIN in coding string.
    VCDS can't do this automaticly in this type of ESP.
    So i make this tutorial how to make it manually.
    For example.
    ESP coding is:
    108724AD09A6089824A690767A6416
    And VIN is:
    WV2ZZZ7HZAH123456
    In ESP coding used 5 last digits of VIN (2,3,4,5,6)
    They located in 6,8,10,12,14 bytes of coding string:
    byte 6 = A6
    byte 8 = 98
    byte 10 = A6
    byte 12 = 76
    byte 14 = 64
    For convert this bytes to digits of VIN and back, used this table:
    VIN#13 VIN#14 VIN#15 VIN#16 VIN#17
    0 - A4 0 - 95 0 - A2 0 - 71 0 - 5E
    1 - A5 1 - 96 1 - A3 1 - 72 1 - 5F
    2 - A6 2 - 97 2 - A4 2 - 73 2 - 60
    3 - A7 3 - 98 3 - A5 3 - 74 3 - 61
    4 - A8 4 - 99 4 - A6 4 - 75 4 - 62
    5 - A9 5 - 9A 5 - A7 5 - 76 5 - 63
    6 - AA 6 - 9B 6 - A8 6 - 77 6 - 64
    7 - AB 7 - 9C 7 - A9 7 - 78 7 - 65
    8 - AC 8 - 9D 8 - AA 8 - 79 8 - 66
    9 - AD 9 - 9E 9 - AB 9 - 7A 9 - 67
