Seat Ibiza 1.4 16V immo and ecu problem

[armpower]

Hallo

I've a problem with 2003 Ibiza 1.4 16V ecu number 036906034DG.
The car have a dead battery problem.
So the ecu is locked and dashboard immo loight blink.
I've taken apart the ecu, read the 29F400 flash and reflashed with file taken from the forum.
Also the ST95080 was corrupted.No Vin and Pin number inside.
I've write a file (taken from here) inside with 95080.
After that i've tried to code the ecu with new file and pin number with the help of VAG-Can professional.
The procedure was:
Login to ecu
go to adaption channel 50.The value inside field is 32000, i've written the dashboard pin and clic test button.
The dashboard immo stop blinking and after a couple oif second the procedure abort with a 31 error.
I've tried also virgin st95080 file but no luck.I can't code the ecu to dashboard.
So my question is.
What is the correct way to code this ecu to dashboard? I haven't the original ecu pin code but only the pin from a new file.
Please explain me the correct way to do coding.
In dashboard there isn't any time lock all value are 0.
In alternative.Have you got a couple of working file for this ecu?
The vdo dashboard is 06L0920820H Ecu 036906034dg

Many thanks for your time and effort

Thanks.

I know.Marelli 4MV doesn't have any immooff.
I'm searching a good 95080 to write back to the ecu and pair the ecu with dashboard.
Also I'm searching a guide or tips to perform a coding because I've tried several time with no luck.

Hallo mates.I've solved the issue.
Was a stupid error during coding.
In the first attemp to code the ecu, i've done login, adaption channell 50, inserted the dash pin than I pushed the test button and waited something to happen.http://www.~~~~~~~~~~~~~~~~~~~~~~~~~~~/images/smilies/sadsmile.gif
So after a couple of second the error 31 came and the procedure abort.
The correct procedure is :
Insert dash pin, push test save and close in sequence without any pause beetween.
Now the ecu is coded correctly and the car start.
