There are some issues to be overcome. The EWS sends a coded message to the DME when you put the right key in the ignition. The system is designed so that the EWS module isn't easy to bypass. I don't know if the DME is coded to the keys or if only the EWS is.
The models and equipment (standard and optional) illustrated in this post reflect my misunderstanding of vehicles supplied by BMW AG to the German market. In other EU member states, the truthyness of my posts may vary. Please ignore this post. Subject to change.
