Jetta 2010 immobiliser issue discusion

[issam216]

I tried to make a spare key for a VW jetta 2010 uds 9s12 dash with clone avdi, i done the
Job with sucess but car didn't start... Even the original key didn't make the car anymore.
I tried to make verification and when i read the immobilizer data after programming
I observed that all data was ok (vin, pin, number of keys) except Cs bytes In place of reel
Cs byte 00000000000000 was displayed.....

I extracted six byte from ecu and pin but with my tool i failed to extract the 7th byte
From the existing key...

My question is ; if i brought an original avdi can I extract the 7th byte from key and
And can update the immo with the correct data. ?

If i failed to extract the 7th byte can i put back the First six byte to the immo data
And choose any 7th byte from my mind and erease existing and make new keys with the
Choosen byte?

Thank you for helps
