I have yanhua mini acdp with Module1/2/3 . I am using a key programming device mainly fem bmw. I have a question I would like to exchange fem for another one and write the whole and then read the second fem and using the write immo data function. I loaded the original by selecting write all but auto after changing fem not if it’s possible with yanhua at all…

1.Do you have a working key for the damaged FEM module? If have, please put the working key into coil to backup IMMO data.
2.Write the IMMO data to another FEM module, you need to add a new key follow the guide to do all keys lost.
