Audi A8 2008 kessy pin cs help

[Pepko bonchev]

So i have a customer with audi a8 2008 3.0 tdi
And we have to make a spare flip key with keyless...is it any chance to get the pin code and cs bytes from obd or i have to read the eeprom dump from the kessy on the bench. Programs that i have are vvdi key tool plus and abrites.

obd with abrites and protag

I think that Vvdi key tool plus should do it via obd as well…

It doesnt work with both programs. I tryed to get the pin and cs from autodetect pin cs, with wizard mode with standart mode, from the working key all this ways doesnt work. I though the kessy or something doesnt work right so i scan it for dtc and opens every unit and does not have dtc.
Also forgot to mention that the transponder is id46.
Is it there something that i miss or i have to go on the bench

Since both tools don’t work via obd, I am afraid that you have to do it on the bench.
