This procedure details how to change the Engine Control Unit (ECU) on VW/Audi/Seat/Skoda vehicles with Immobilizer IV.

Determining VIN (ECU) & IMMO-ID/Challenge

[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 (does not apply for all models).
[Done, Go Back]

On models which do not have an IMMO-ID you need to use the IMMO-Challenge instead.
[Advanced ID - 1A]
See the field IMMO-Challenge for the current value, keep in mind that the challenge changes with every ignition cycle!
[Close Controller, Go Back - 06]


Determining VIN (Instrument Cluster) & IMMO-ID/Challenge

[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 (does not apply for all models).
[Done, Go Back]

On models which do not have an IMMO-ID you need to use the IMMO-Challenge instead.
[Advanced ID - 1A]
See the field IMMO-Challenge for the current value, keep in mind that the challenge changes with every ignition cycle!
[Close Controller, Go Back - 06]


Engine Control Unit (ECU) Swapping (Used ECU)

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) ECU to the NEW (USED) ECU.
  • Make sure to have BOTH PIN's, from the OLD (ORIGINAL) and the NEW (USED) ECU.
  • Make sure to have the Radio Code (for factory radios only).


[Select]
[01 - Engine]


[Security Access - 16]
For the following procedure, use the PIN of the NEW (USED) instrument cluster.
There are 2 possibilities how to enter a PIN, choose the one that applies for you.

  • 4/5-digit PIN
    • The PIN needs to be entered as 5-digit number. For example, if your PIN is 1234, enter 01234.
  • 7-digit PIN
    • [Use 7-digit PIN/SKC]
    • Enter the 7-digit PIN, Date on which the PIN was generated by the dealer, along with the Workshop Code (WSC) and the Importer number of the dealer that generated the code.
    • [OK]
    • VAG-COM will validate the data you have entered and return you to the Login screen, where the Login Code will show as "XXXXX".

[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.
There are 2 possibilities how to enter a PIN, choose the one that applies for you.

  • 4/5-digit PIN
    • The PIN needs to be entered as 5-digit number. For example, if your PIN is 1234, enter 01234.
  • 7-digit PIN
    • [Use 7-digit PIN/SKC]
    • Enter the 7-digit PIN, Date on which the PIN was generated by the dealer, along with the Workshop Code (WSC) and the Importer number of the dealer that generated the code.
    • [OK]
    • VAG-COM will validate the data you have entered and return you to the Login screen, where the Login Code will show as "XXXXX".

[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) ECU now shows the VIN/IMMO-ID of the vehicle now.
