I'm not aware that you can do immo off in the EEPROM. Virgin, yes, but not immo off.
Read flash and post here and see if you can get some help.

Try this file and report. Not tested so it might not work.

The checksum might be wrong in the previous file. Try this one also.

Hello,

Here is a solution for total immo off. It is to be done on the bench but I would try it first with serial and see if it works.

331388

Here are the instructions:
1) Click on Save and unpack the .zip archive

2) Connect the serial interface as follows:
KLine = P53
-12V = P24, P25, P49
+ 12V = P15,16,32,47,48
Pin 20 = Boot Mode (GND)

3) To enable the programming put
in Boot Mode (GND) the P20 for 3 seconds

4) Program with a file according to
the displacement of the car.

And here is the file:
331390

Do not forget to disconnect the immo box.

Try it and let us know results.

Best Regards

Those are the files from IUD3.2. They are always posted when someone asks for ME7.3.1 immo off files.
It is possible that they work for some cars, but I have never seen that they actually do.

It would be interesting to hear if someone have had sucess with them, and on what Alfa/model/engine.
