VAG immobiliser emulator schematic diagram
Project of immobiliser Emulator for VW, Audi, Seat and Skoda vehicles.
Fast, easy and cheap solution for emulate immobiliser in case of defect Immo Box, Transponder Coil etc. in old VAG vehicles (Immo-1 and Immo-2). Presented solution is used from many years. It has some drawbacks, but is simple, tested and working. Project based on AT89C2051 microcontroller and can be modified in many ways. Working emulator, in the basic version can be assembled within several minutes.
Here you can download a binary file for programming AT89C2051 for this project.
