Engine ECU 51871693 (MJD8F2.G3) – description
On this page you can buy ECU 51871693, a Magneti Marelli MJD 8F2.G3 unit intended for the Fiat Grande Punto 1.3 Multijet. It goes through a function test before dispatch.
Coding to the immobiliser
- Virgin: the ECU codes itself after fitting – no programming, with a matching part number and a working immobiliser.
- IMMO OFF (on request): the car drives, but a red immobiliser warning is shown on the dashboard and a fault stays in diagnostics that cannot be cleared without pairing with the immobiliser.
- We recommend Virgin, as it leaves no fault.
Symptoms that may point to an ECU failure
- Diagnostics cannot connect to the ECU.
- The engine will not fire, the injectors get no signal.
- The fault appeared after water got in or after a short in the harness.
- The ECU has no power despite working fuses.
The cause may also be the wiring, the power supply or a sensor. Diagnose first, then buy.
Warranty and extra services
The ECU comes with a warranty of 6 months. Every unit passes a bench test and a test in our test car.
- Paid options on request: EGR OFF and DPF OFF.
