Cluster Swapping with Immobilizer II
Posted  3 Dec. 2002

Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk.

This procedure details how to install a NEW Instrument Cluster in Immobilizer-equipped VW/Audi vehicles with Immobilizer II . As of 11 Mar. 2002, VW and Audi are providing 7-digit Secret Key Codes in place of the earlier 4-digit SKC's. Keys must be coded using the new 7-digit SKC (secret key code) method unless the owner still has the correct 4-digit code.

Immo-3 knows your car's VIN. Access 17-Instruments (or separate 25-Immobilizer on vehicles that are set up that way) and look at the first "Extra" field.

If you see something like: "Immo-ID VWZ7Z0W0648696"  You've got Immo-2 (or maybe even Immo-1 in earlier non-US models).

If you see something like "WVZKB58001H231169 VWZ7Z0W0648696" You've got
Immo-3. The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.

Procedure for installing a NEW  Instrument Cluster in vehicles with Immobilizer II:

--- Reading the Old Cluster ---

1. With the OLD Instrument Cluster in the vehicle, write down the current mileage.
    

2. (Volkswagens only, if you are working on an Audi, skip to step 3)
   [Select] 
   [Display] (Less Common Modules) 
   [19 - CAN Gateway]
   Write down the 5 digit number from the "Soft. Coding" field, make note that is the CAN coding.
   [Close Controller, Go Back - 06]
    

3. [Select] 
   [17 - Instruments]
   Write down the 5 digit number from the "Soft. Coding" field, make note that is the Instrument Cluster coding.

   [Close Controller, Go Back - 06]
    

6. Take that 14-digit Immobilizer ID number (along with your VIN number) to your dealer and request your seven-digit SKC, along with the workshop code and importer number ( the workshop code and importer number can be found in the upper-right corner of the Administration screen of the dealer's VAS 5051 - for more info, see the Options Screen Page).
   
   --- Recoding the New Cluster ---
    

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

8. (Volkswagens only, if you are working on an Audi, skip to step 9)
   [Select] 
   [Display] (Less Common Modules) 
   [19 - CAN Gateway]
   [Recode - 07]
   Enter the 5 digit number that you wrote down as the CAN coding.
   [Do It!]
   [Close Controller, Go Back - 06]
    

9. [Select] 
   [17 - Instruments]
   [Recode - 07]
   Enter the 5 digit number that you wrote down as the Instrument Cluster coding.
   [Do It!]
   
   --- Matching the New Cluster to the Engine ECU---
    

10. [Adaptation - 10]
    Enter 00 in Channel Number
    [Read]
    [Save]
    [Done, Go Back]
    [Close Controller, Go Back - 06]

    [Do It!]
     

14. [Adaptation - 10]
    Enter 21 in "Channel Number"
    [Read]
    The "Stored Value" is the number of keys currently matched.
    Enter "new value" of 0
    [Save]
    This clears out the old key-matchings.
    Enter a "new value" corresponding to the total number of keys to be matched, including any existing keys
    [Save]
     

15. [Done, Go Back]
    [Close Controller, Go Back - 06]
    Switch ignition off and remove key

    --- Entering the Mileage in the New Cluster ---
     

18. [Select]
    [17 - Instruments]
    [Adaptation - 10]
    Enter "channel number" 09 to select channel
    Put in the number of km divided by 10.  Example: If old cluster had 50,357 km, put in 5036.
    Note:  Some clusters may require a Login of 13861 before you can set the mileage.
    [Test]
    Observe the Instrument Cluster and make sure the mileage displayed is correct. Once you save this value, you will be unable to change the mileage EVER!
    [Save]
     

19. Make sure all keys start and run the vehicle, and that the mileage reading is correct.
