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 1.4 TDI reliable?

It depends on the generation. The unit-injector one (1999-2010) calls for watching the timing belt - which also drives the unit injector pumps - the water pump, the turbo and the EGR, with a DPF only on the last BlueMotion/Ecomotive versions. The later EA288 (2014-2019) is not singled out by dieselgate, which according to the sources consulted was limited to the EA189, but it shares the need to watch the belt, turbo, EGR and DPF.^[8][9][10]
