ECU 52096056 – what to know
We offer a working MJD 9DF.G1 unit (Magneti Marelli) with part number 52096056. It controls the engine of the Fiat 1.3 Multijet. We test every unit before dispatch.
Possible symptoms of a faulty ECU
- the engine does not start, no injector control,
- no communication with the ECU during diagnostics,
- no power supply to the ECU although the fuses are fine,
- failure after water ingress or a short circuit in the wiring.
These symptoms can also have other causes – wiring, power supply or sensors. Run a diagnosis before buying.
Does this ECU fit your car?
MJD 9DF.G1 units went into Fiat vehicles with the 1.3 Multijet engine. The model and year alone are not enough. Look at the label of your ECU: if it shows number 52096056 and type MJD 9DF.G1, it is the same version. A different part number is a different ECU.
Virgin or IMMO OFF
- Virgin – Plug & Play: after fitting, the ECU codes itself to the car and immobiliser, no programming needed. Condition: matching part number and a working immobiliser.
- IMMO OFF on request: the car runs correctly, but a red immobiliser warning appears on the dashboard and a fault is stored in diagnostics that cannot be cleared without pairing with the immobiliser. The Virgin version does not have this fault.
Preparation before dispatch
- Bench test.
- Fitting and check in our test car.
- On request, for an extra charge: chip tuning, EGR OFF and DPF OFF.
Instead of the Virgin version, we can also clone your old ECU at no extra cost – we then need the data from your current unit. Warranty on the ECU: 6 months.
