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 2.3 dCi (M9T) reliable?

The 2.3 dCi M9T is a van diesel with good durability if maintenance is kept up. The weak points cited are the EGR and the turbo, the injectors, and the particulate filter in urban use; the sources are mostly opinion websites.[8][9]
