How to Choose the Right 51843361 ECU for Your Fiat Grande Punto

The label on this unit shows the identifiers MJD 6F3.PI and "G.PUNTO 75HP UEGO SM2". Before ordering, check that these match the markings on your original engine control unit.

Vehicle Compatibility

Fiat Grande Punto 1.3 MultiJet 75 HP – selected versions only.

Compare part number 51843361, ECU type MJD 6F3.PI and reference 71600.254.00. The hardware version is identified on the label as HW04P/3641-PI90. Vehicle model and engine power alone are not sufficient to confirm that two ECUs are interchangeable.

ECU Preparation and Installation

This ECU has been prepared in Virgin Plug & Play condition. Once installed in a compatible vehicle with a fully functioning immobiliser system, it should adapt automatically. The vehicle's immobiliser remains active. If the numbers on your original ECU differ, please send us a clear photo of its label so we can check compatibility before purchase.

Frost, Snow and Moisture: Why Do ECU, BCM and ABS Pump Faults Occur in Winter?

Why Do Engine ECU and Vehicle Electronics Faults Occur in Winter?

ABS and ESP warning lights and the engine management light coming on after a cold night do not necessarily mean that a control unit has failed. Voltage drops, a discharged or ageing battery, moisture or water entering the vehicle’s electronic modules may be the cause.

In this ECUSale guide, we look at problems affecting engine ECUs in the Audi Q7 and Opel Corsa D 1.3 CDTI, as well as Volkswagen ABS pumps. We also explain how to recognise a water-damaged control module and what to check before replacing it.
