The part is bench-tested before shipment and sold as-is, not coded for your vehicle. To start the engine, coding/pairing to the immobilizer and VIN is MANDATORY, to be performed via an optional service or by an equipped professional. Available references below (HW/SW) to verify compatibility with your original unit. This Bosch ME7.4.4 is a cost-effective alternative to new, while remaining a sound base for compliant adaptation on your car. Please carefully check the markings on the label and the unit before ordering.

Overview

The Bosch ME7.4.4 engine ECU is the electronic unit that oversees injection, ignition, throttle control, and coordination of engine actuators. Part of the Bosch ME7 family, it processes sensor information (temperature, pressure, position, airflow, etc.) in real-time to adjust engine operation for stable and efficient combustion. It also ensures communication with other modules via the vehicle network and manages immobilizer-related authentication.

In a PSA/Stellantis group vehicle, the Bosch ME7.4.4 plays a central role: without correct pairing, the engine will not start. Therefore, any replacement requires electronic adaptation. This reference is offered here as a used part, bench-tested, ready to be coded to join your vehicle architecture after verifying hardware and software compatibility.

Your ECU at Incarline

This Bosch ME7.4.4 is offered as a used part, bench-tested before shipment. It is sold as-is, not coded and not programmed for your car. A functional check is performed to validate communication and essential ECU functions under simulated conditions. Applicable warranty terms are specified at the time of order on the product page.

For integration into your PSA/Stellantis vehicle, coding/pairing is MANDATORY. Depending on your needs, options can be added to the cart via the configurator (e.g., cloning, programming, or immobilizer-related solutions), or the intervention can be performed by a workshop with the appropriate tools. Finally, to avoid any errors, we recommend confirming the exact HW/SW references of the Bosch ME7.4.4 before purchase and planning the necessary electronic intervention during installation.
