Have you selectd K-line from the drop down menu at the bottom left?
As ddillenger mentioned.
there after select 07 Kombi (meaning cluster). Select connect.
now read your Pin.
If you have a late 2006 or newer. Vag +K Commander 2.1-2.5 will not work. You will need to use V3.6 (with associating cable).
You can now pull the SKC in order to program new keys.
You are able to code new keys using Vag +K if you want. I personally have found that utilizing VCDS with SKC seems more reliable.
