This is the second FEM I am having an issue with this week, I keep getting these error messages.
(Ecu is missing some flashing info, You cannot downgrade. Do you want to restore it?)
Second message
(Error in Communication with WVCI)
I restored it and it goes back and forth with same message between the TWO error messages.
Extra key on both cars, put the car back together and the car start with original key.
