This is a small but very sophisticated engine immobilisation ECU, interacting wirelessly with a chip in the Key fob to validate correct ownership and then with the engine ECU using rolling code communication algorithms. Engine management ECUs can only learn codes once so after installation this ECU and the engine management form a unique pair. It is a very secure system, owed mainly to the fact that BMW control production and core programming of every single unit produced. This means replacements can only be ordered by VIN number through dealers and proof of legitimate vehicle ownership. As it is an ECU which is unique for each vehicle it is also used to store vehicle specific information.
