Engine Control Unit (ECU) Swapping (USED ECU)
Prerequisites:
- The REPLACEMENT (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 ORIGINAL (OLD) ECU to the REPLACEMENT (USED) ECU.
- Make sure to have BOTH PIN's, from the ORIGINAL (OLD) and the REPLACEMENT (USED) ECU.
- Make sure to have the Radio Code (for factory radios only).
[Select]
[01 - Engine]
[Login - 11]
For the following procedure, use the PIN of the REPLACEMENT (USED) ECU.
- 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.
[Do it!]
[Adaptation - 10]
Enter 050 in "Channel Number".
[Read]
For the following procedure, use the PIN of the ORIGINAL (OLD) ECU.
- 4-digit PIN
- The PIN needs to be entered as 5-digit number. For example, if your PIN is 1234, enter 01234.
[Test]
- The values may change to "32000", this is normal
[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 REPLACEMENT (USED) ECU now shows the VIN and if supported IMMO-ID of the vehicle now.
- Verify that the REPLACEMENT (USED) ECU has the same Coding as the original unit, or code it from scratch using the repair manual or coding chart in VCDS when applicable.
Engine Control Unit (ECU) Swapping (NEW ECU)
Prerequisites:
- 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]
[01 - Engine]
[Adaptation - 10]
Enter 050 in "Channel Number".
[Read]
For the following procedure, use the PIN of the CAR.
There are 2 possibilities how to enter a PIN, choose the one that applies for you.
- 4-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.
- This information is NO LONGER GIVEN OUT by dealers and has not been since 2005 as explained here.
- [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".
[Test]
Check the 1st measuring value.
[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 ECU now shows the VIN and if supported IMMO-ID of the vehicle now.
- Verify that the NEW ECU has the same Coding as the original unit, or code it from scratch using the repair manual or coding chart in VCDS when applicable.
- Activate Cruise Control if needed on new DBW ECU's
Activating Cruise Control on a new ECU (DBW)
DBW (Drive-by-Wire) Factory fresh ECU's often come with cruise control de-activated.
