ECU/TCU replacement with ZN051 DS Box and EM003 emulator (IMMO III/IV EMU)

The procedure to use when you have to replace an immo module with an emulator: the EM003 emulator emulates the engine ECU or the transmission ECU within the IMMO system. It is mainly needed when the CS and PIN of the ECU or TCU cannot be read without opening the unit. It applies to the transmissions of Audi A6 2003-2010, Audi Q7 2005-2015, Audi A8 2003-2010 and to all Immo III/IV engine ECUs (EDC16/EDC17/ME7/MED9/MED17/Simos petrol/Simos PPD/Simos PCR/Magneti Marelli/Delphi). It lets you fit immo parts to another vehicle, even of a different make or power output.

Procedure

1. Read the PIN and CS from the engine ECU (in the manual's example an EDC17 in diagnostic mode). Alternatively you can try reading them from "Immo parts adaptation" > "Engine Control Unit".
2. Go to "IMMO PARTS ADAPTATION" and open "IMMO III/IV EMU".
3. Enter the data read from the ECU.
4. Press "OK" and make sure the emulator is connected to the vehicle's internal CAN-BUS (it can also be connected through the DS box during the procedure).
5. Emulator connections: RED = CAN High, BLUE = CAN Low, YELLOW = B+, BLACK = GND.
6. Select the unit you need (in the example, the master ECU).
7. Start the procedure: check you have an internet connection and a power supply on the car, then wait for the calculation to finish.
8. Alternatively you can write the immobiliser data into the ECU/TCU manually by selecting "Immo parts adaptation" > "Immo III/IV Emulator Write Data".
