    Default Audi TT 8j cluster replace 8j0920930 help

    Hi,
    has anyone a solution for me.
    A costumer came with a ,,new'' dash (it is used and Safe in the display) and i would like to learn it to his car with FVDI 2018.

    I read Pin / CS / MAC by ECU. Then i tried to read config and immo data by dash. No communication because security acess faild.

    Then i used a trick and read the eprom 24c32 with a programmer, saved the dump and load a damage dump to it.

    After installation back in the car the display show DEF and i can write the org dump back via OBD.
    Now i can read config an immo data, but immo data locks like not good only the VIN is correct. I think fvdi decrypt eprom / micronas wrong. So i can't upload new immo data.

    After Dash reset it show Safe again.

    Can anyone tell me a solution or how to fix the problem with fvdi or something like that.

    Thaks in advanced

    Service mode has destroyed Immo Data. You need the original key to learn a new cluster

    Thanks for your answer,
    But i have Not tryed a Service Mode, i have write a ,,damage“ dump to 24c32 and After Installation i Write back the org dump. With this Trick you become acess to the eprom and immo Data normaly.
    This is a „all lost key“ Solution for 24c32 and 3217g micronas
