Bmwemulator User Manual (

This device can emulate BMW EWS2 and EWS3.2 immobilizer systems for cases where the original system is faulty or transponders are lost or damaged. It connects to the vehicle's diagnostic port to program the device with the correct vehicle-specific ISN number via software. Once programmed, it replaces the factory EWS module to allow vehicle startup and operation without the need for the original transponders or system. The installation requires removing the factory EWS unit and connecting the emulator in its place.
