BMW FEM Car Won't Start with ELV fault after Mileage Reset

 Problem:

After FEM mileage reset car would not start. I used Yanhua mini ACDP. Coming up with ELV fault ((Electric Steering Lock), ELV signalling authentication fault.). Resetting ELV and STARTER MOTOR with ISTA allows me to turn the ignition on, but car still wouldn't start. Put backup back in to the fem and look what happens. Still same thing. Dead FEM? 

Solution:

Remove the bloody ELV out. Virginised the ELV and all is good.
