The answer is yes. Only to ensure the BMW control unit FEM is completed and dry enough, Xhorse VVDI2 is able to read FEM data after water damage. Besides, BMW key data still can be saved via VVDI2.
Following is an experiment:
BMW >> Key learn >> FEM/BDC Key Learn >> Get key info
There are 2 enable keys.
Currently no key is in ignition switch.
Read FEM data OK.
Insert a working key into GODIAG BMW FEM Test Platform.
Click “Get key info” again.
It tells “Key 2”.
That means the FEM is still workable for key programming.
Trial is successful!
