ECM Matching


  • Battery voltage at least 12.5 V.
  • Immobilizer II ECM

[17 - Instruments]
[Adaption - 10]
Leave channel at "00"

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

Turn ignition OFF for 15 seconds. Start vehicle.


  • For cars with a separate Immobilizer (Includes 2000+ EuroVan, Cabrio, and many older non-US models), use [25 Immobilizer] instead of [17 - Instruments]. The rest of the procedure is the same.
  • On some Euro Audi models with Immobilizer 2, a PIN will be required.
