'''[Done, Go Back]'''<br>
'''[Close Controller, Go Back - 06]'''<br>


=== Immobilizer (integrated in Kessy) ===

'''[Select]'''<br>
'''[05 - Start/Access Authorization]'''<br>
Look at the first "Extra" field. The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.<br>
'''[Close Controller, Go Back - 06]'''<br>

---OR---

'''[Select]'''<br>
'''[05 - Start/Access Authorization]'''<br>
'''[Meas. Blocks - 08]'''<br>
Select Block 081.<br>
'''[Go!]'''<br>
''The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.''.<br>
'''[Done, Go Back]'''<br>
'''[Close Controller, Go Back - 06]'''<br>


== Engine Control Unit (ECU) Swapping (USED ECU) ==

'''<u>Prerequisites:</u>'''<br>
* The NEW (USED) ECU is installed in the car.
* Battery voltage at least 12.5 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]'''<br>
'''[01 - Engine]'''<br>


'''[Login - 11]'''<br>
''For the following procedure, '''use the PIN of the NEW (USED) ECU'''.''<br>
''There are 2 possibilities how to enter a PIN, choose the one that applies for you.''<br>
* '''4-digit PIN'''
** The PIN needs to be entered as 5-digit number in the New Value box. ''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!]'''<br>


'''[Adaptation - 10]'''<br>
Enter 050 in "Channel Number".<br>
'''[Read]'''<br>

'''[Done, Go Back]'''<br>
'''[Close Controller, Go Back - 06]'''<br>


* 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 and if supported IMMO-ID of the vehicle now.


== Engine Control Unit (ECU) Swapping (NEW ECU) ==

'''<u>Prerequisites:</u>'''<br>
* The '''NEW''' ECU is already 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 ECU.
* Make sure to have the PIN of the CAR.


'''[Select]'''<br>
'''[01 - Engine]'''<br>
'''[Adaptation - 10]'''<br>
Enter 050 in "Channel Number".<br>
'''[Read]'''<br>

'''[Test]'''<br>
Check the 1st measuring value.<br>
'''[Save]'''<br>
'''[Done, Go Back]'''<br>
'''[Close Controller, Go Back - 06]'''<br>


* Switch OFF the ignition and let the car sit for ~1 minute, then switch ON the ignition again.
* Verify that the NEW ECU now shows the VIN and if supported IMMO-ID of the vehicle now.
