Tempomat does not work (Cordoba 6L2)

Finally, I tackled the cruise control.

Everything is installed and wired... so far so good.



With VAG unlocked ......the system also recognizes it

Only works if it doesn't.

OK, entered the measurement block ……… code 006 or 022 and tested

For each: / Each press of a key generates values.

Change as per the instructions.

000000 Cruise control off

000001 Cruise control on

000101 Press the button

001001 RES Position

100001 Clutch engaged

010001 Brake applied

until: 'Switch B to 'OFF', before the power-up point'
Nothing happens...no bit changes.

I don't really want to run, but I also don't want to stop.

Somehow, according to the installation instructions, the values should end with a 11.
(example =001011 RES Position and not like mine 0010(0)1)
Does this missing bit have anything to say, or is it simply STG dependent?

Does anyone know what might be causing this?
PS: I used the search function and found nothing. There was no one else with the same name.
Problem BUT also without a solution.
