Hello Members,
maybe someone can help me with immo off from a ST 95080 eeprom.
It is from a Magneti Marelli ECU.

(VW Lupo) Ecu Version is: IAW4LV.TA (036998034 AQ)

The problem is I cannot calculate checksum on line 95.

Would be great if someone can help me.

Thank You!

Cheers

Hello members,
after some research and tool solution compared I think I have solution:
Line 93: 02 (-1)
Line 95: 24 (+1)

Thanks to carlabimmo and Idecoder.

There are a Lot of tutorial outside showing A8 in Line 95, but Iam very sure checksum has to be corrected manually in Line 95. So if someone has a hint or if iam completely wrong please tell me/us.

Have a good night mates

On this particulary ecu will not work.

Hello lupu_sandu,
thanks for Your feedback. So You know what will work for this ECU? Maybe emulator (Julie) solution? Or is there a eeprom modification possible? I thought this is Immo 3 system because of vin in eeprom, but maybe iam wrong .
If You have a hint for me how to get this ECU immo off, it would be great.
Maybe also interesting for You: the readout and writing process only worked with xprog, I tried first hextag and got all the time ff readout, also upa didnt read it well (i got only 0 readout), only xprog worked for me completly without problems (but this only as a hint, this eeprom makes me headache).

Thank You

Immo3 system with pin and vin in ecu.
But why immo off? You can pair with cluster easy.

Hello lupu_sandu,
this is a second hand ECU because original one has for sure a powerloss failure and I wanted to try this ECU for testing the powerloss problem with identical ECU. Can You explain what You mean with You can pair with cluster easy?

Thank You

Did you try swap eeproms for test

Your ecu pin code is : 02970
In case you need

Hello raffy haddad, the car is driving with original ECU (my friend plug it off over night) and is far away from me, got second hand ECU via post and wanted to make immo Off in first try. But Youre completly right, eeprom duplicating is next step if immo off will not work (but will Take time till original ECU arrives and car is in this time Not driveable). Just wanted to give it a try.
Also thank You for the ECU Pin code. I also calculated the Pin Code and got: 31267
How do You calculated it? I used Idecoder, but maybe protocoll was wrong because of iaw4mv and not iaw4lv readout.

Thank You

Your ecu pin code is = (0)2970

[Dashtailes]

Your ecu pin code is = (0)2970

Thank You keyzex for giving this hint,
seems like Panos Software also says "For the iaw4.lv with vin number inside the programm shows the pin. No immo off for this Ecu."

Same Like raffy_haddad said.

So maybe only way is cloning eeprom and test.
But I will give immo off solution a try and report back.

Thank You
