Your said: Hello everyone. Fiat ducato 250 Ecu Visteon engine. Mil light on the dashboard and fault code P1304 with MES impossible to clear. Thanks for your help.

Code P1304 is P1304 = EGR Calibration High

Check for EGR faults

Thanks for your help. The fault code given by MES is: P1304 pilot injection learning. The 4 injectors are new with their codes correctly recorded and visible in the Visteon engine ECU parameters. I cannot learn or clear the MIL light.

If MES is saying P1304=pilot injection learning then I assume MES is using the correct code description for your vehicle/Ducato.

The code discription I quoted was from a Fiat generic list of codes.

Did you replace the injectors at some point in time? It could be that the ECU is not happy with the coded values. e.g. fuel adjustment required for those codes it outside of the ECU's range.

Sugget you web search for "P1304 pilot injection learning" etc.
