Is the 2.3 MultiJet reliable?

The 2.3 MultiJet (F1A) in the Fiat Ducato and Iveco Daily has few faults with a solid source: the best documented are three campaigns on the 2016-2019 Euro 6 Ducato (intercooler hose, EGR pipe and camshaft). Owners and garages also cite EGR, throttle body, injectors and AdBlue, almost always on forums or commercial websites, with no statistics.[1][2][3][4][5][6][7]

Is the Isuzu 2.5 / 3.0 / 1.9 Ddi reliable?

These are the diesels of the Isuzu D-Max: the 2.5 twin-turbo (4JK1) and the 1.9 Ddi (RZ4E) of the European range, and the 2.5 and 3.0 of the Latin American Chevrolet D-Max. Auto Express speaks of enviable reliability; what is documented is diesel in the oil of the 2.5 on short journeys, soot in the EGR and a 2017 campaign for the camshaft gear.[8][9][10][11]
