Immobilizer IV Immobilizer Swapping (Instrument Cluster)

From Ross-Tech Wiki

This procedure details how to change the instrument cluster on VW/Audi/Seat/Skoda vehicles with Immobilizer IV, where the immobilizer control module is integrated in instrument cluster. See the separate instructions for models where the immobilizer control module is integrated in kessy (Keyless Entry and Start SYstem).


Determining IMMO-ID & VIN (ECU)

[Select]
[01 - Engine]
[Meas. Blocks - 08]
Select Block 081.
[Go!]
The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID..
[Done, Go Back]
[Close Controller, Go Back - 06]


Determining IMMO-ID & VIN (Instrument Cluster)

[Select]
[25 - Immobilizer]
[Meas. Blocks - 08]
Select Block 081.
[Go!]
The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID..
[Done, Go Back]
[Close Controller, Go Back - 06]


Instrument Cluster Swapping (Used Cluster)

Prerequisites:

  • The NEW (USED) cluster is installed in the car.
  • Battery voltage at least 12.0 V.
  • All relevant coding and adaptation values have been transferred from the OLD (ORIGINAL) cluster to the NEW (USED) cluster.
  • Make sure to have BOTH PIN's, from the OLD (ORIGINAL) and the NEW (USED) instrument cluster.
  • Make sure to have the Radio Code (for factory radios only).


[Select]
[25 - Immobilizer]


[Security Access - 16]
For the following procedure, use the PIN of the NEW (USED) instrument cluster.

  • 4-digit PIN
    • Enter zero followed by the 4-digit PIN. For example, if your PIN is 1234, enter 01234.

[Do it!]


  • The instrument cluster now shows Immobilizer Adaptation active, wait until it changes to Immobilizer active - this may take up to 2 Minutes.


[Adaptation - 10]
Enter 050 in "Channel Number".
[Read]
For the following procedure, use the PIN of the OLD (ORIGINAL) instrument cluster.

  • 4-digit PIN
    • Enter zero followed by the 4-digit PIN. For example, if your PIN is 1234, enter 01234.

[Test]
[Save]
[Done, Go Back]
[Close Controller, Go Back - 06]


  • Switch OFF the ignition and let the car sit for ~1 minute, then switch ON the ignition again.
  • Verify that the NEW (USED) instrument cluster now shows the VIN/IMMO-ID of the vehicle now.
  • Proceed with Key Matching now.


Special Notes

If Adaptation Channel 050 is not saving when the PIN is confirmed to be correct make sure the WSC/Importer/Equipment numbers are NOT all zeros before clicking Save. If address 25-Immobilizer shows all zero details (Shop #: WSC 00000 000 00000) in the Auto-Scan after failed matching they can be changed on the VCDS program [Options] screen. Any value that is not all zeros or ones should work.
