“Look at the first "Extra" field. If you see something like: Immo-ID VWZ7Z0W0648696" then you've got Immo-II (or maybe even Immo-1 in earlier non-US models).If you see something like WVZKB58001H231169 VWZ7Z0W0648696 then you've got Immo-III. The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID. “ [Close Controller, Go Back - 06]

Key Matching

Prerequisites:

• While adapting each key, make sure to place the other keys away from the ignition lock (reader coil). The passenger seat is an adequate place.
• Battery voltage at least 12.5 V.
  

[Select]
[17 - Instruments]
Write down the 14 digit Immobilizer ID number from the "Extra" field
[Meas. Blocks - 08]
Select Block 002.
[Go!]
The value in field 3 must be 1. If value is not 1, the key is not capable of being adapted to Immobilizer.
You can check each key in this manner.

  1.

     [Select] 
     [17 - Instruments]
     Write down the 14 digit Immobilizer ID number from the "Extra" field
      
  2.

     Take that ID number to your dealer and request your seven-digit SKC, along with the workshop code and importer number (all this information can be found in the upper-right corner of the Administration screen of the dealer's VAS 5051). Additional information about how to find the WSC and Importer Number can be found here.
      
  3.

     Measure the car's battery voltage, it must be 12.5 V or higher.
      
  4.

     You can check to make sure a key has the correct electronics in it so that it can be matched to the Immobilizer by:
     [Select]
