After completing the EME repair for BMW F15, F18,F30, i3 and i8 models, an off-vehicle test can be carried out without reinstalling the EME back into the vehicle. This greatly saves time and reduces secondary problems caused by repeated vehicle installations. When purchasing second-hand components, it is possible to determine whether the EME is in good condition before installing it in the vehicle. It is also essential when virginizing the data in the EME.
