Immo off Bosch MED17.4.4: PSA (Citroën/Peugeot)
The Bosch MED17.4.4 ECU is widely used in PSA Group vehicles, including select Peugeot and Citroën petrol models equipped with the 1.6L THP engine. Our solution for this ECU allows permanent deactivation of the factory immobilizer system—ideal for use in ECU cloning, replacement, or start authorization bypass when original keys or BSI/ECU sync data are missing.
This is a fully software-based solution implemented directly on the ECU file. It disables the immobilizer function without triggering diagnostic errors or affecting other ECU operations.
