Introduction:

From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car’s electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.

Why VAG CAN Emulator should be used?/ Working Theory.

IMMO Box (Anti-Theft) must be replaced if car’s engine starts and stops immediately. Immo warning lamp/indicator will flash on the dash panel after engine is stop.
