Does someone know how it is possible to read the pin/skc for a vw lupo with specs from the subject?

I tried to dump with me7_95040_v1.31, vag commander 2.5/5.5, vag k pin  reader 3.9b, vw audi login reader 3.08. And I failed all the time. I have a vcds 12.12.3 clone cable (FT232R).
But it is like the usb to serial isn't working I never see the led flash like when I am working with vcds to connect... I tried rosstech vcp driver, ftdi, changed ept with vagcommander one... I don't know what i can do further more now...

Thanks in advance!

I get already a little bit further with nefmoto but I still can't connect with ecu... I use 10400 baud and slow init because I found it on the forum here somewhere that is needed for an ME7.5.10 ecu...
I was able to get further than coudn't read device in nefmoto by disabling verify cable in dump mode in nefmoto...

But now I Get this:

Thanks for your answer!
What is the best way to do that? Is it also possible through obd to read eeprom from the valeo immo box?
I know its possible to read it via an MAX2990 I²C interface... But I its not that easy anymore to take out the immobox to do that because there are added quite some electrics that are placed before the immo box so I can't get it directly out of the car...

did you read pin from valeobox by obd??? that should be impossible, think you got it from ecu then?

you can just desolder the 24c04 from immobox and read it in external programmer. Or power the immobox and read it using a clip

Hi is there a reply to how someone read the immo box using an obd2 cable ? and has someone made a scope of the proper signal the ecm wants to see for car to be allowed to run? Thanks!

Hi!  so i just read the bin from the valeo immo box 24c04 using an old school willem chip programmer. I did it while on the board using jumper wires and an ecm stand. I looked at the file and used info about where the skc was from info I found in OBD 365. c o m. Used the vagcom and it accepted the code! so a small victory. I had only 5 pins connected. I researched the datasheet from the chip to decipher how to read the chip as far as what to probe. There were pin out holes i put my leads into as some spots so that was handy. Hope this helps! I haven't found info on reading and re writing the ecm to eliminate the immo yet but still fighting.
