Audi TT cluster replace 8j0920930

[J328D]

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 tryed 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
