Possible symptoms of a faulty ECU

- 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.
Choose by part number
This ECU was removed from a Fiat Punto 1.3 Multijet. We match these ECUs by part number only, because the version is decided by the number, not by the MJD 8F3.GG type alone. Number 55261325 on your label must match the number of this unit.
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.
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.
If your ECU has a different part number, check 55250632 MJD 8F3.Q1, 55246587 MJD 8F3.F6, 55260725 MJD 8F3.D4, 51908938 MJD 8F3.S2 or the whole Fiat engine ECU category. About the manufacturer: FPT.
