Engine ECU 55258957 MJD 8F3.GH for selected Fiat Grande Punto 1.3 Multijet 85 HP models, prepared in VIRGIN condition for automatic immobilizer pairing after installation.
The Magneti Marelli ECU offered here has been prepared as VIRGIN with an autocoding function. Once installed in a compatible vehicle, the module automatically pairs with the immobilizer during the first engine start.
Before ordering, compare Fiat part number 55258957 and ECU designation MJD 8F3.GH with your original unit. The label also shows reference BC.0117704.B. Vehicle model, engine capacity and power output alone are not sufficient to confirm compatibility. If the numbers differ, please send us a photo of the original ECU label together with the VIN.
These symptoms may also have other causes. Before replacing the ECU, we recommend checking the power supply, grounds, wiring and stored fault codes.
The VIRGIN autocoding version is prepared to automatically pair with the immobilizer of a compatible vehicle after installation. There is no need to copy immobilizer data from the old ECU beforehand or program the replacement ECU with a diagnostic tool. After the first start, we recommend scanning for fault codes and checking that the vehicle operates correctly.
If you need to retain the data and configuration from the original module, please ask us about ECU cloning. This service requires the original ECU to be sent to us and its data must still be readable.
