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 1.6 CDTI reliable?

The Opel/Vauxhall 1.6 CDTI (2013-2020, 95-160 hp) has no design fault acknowledged by the manufacturer, but it has built up reports of early wear of the timing chain and its tensioner, two episodes (2016 and 2018) of German investigation into a possible EGR valve shut-off, and AdBlue system faults on its Euro 6 versions.[8][9][10][11][12][13][14]
