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 1.8 TDCi reliable?

The 1.8 TDCi (codename Lynx) was Ford's standard diesel between 2001 and 2014, with Delphi common-rail injection and a variable-geometry turbo. It is an engine with well-documented faults: the dual-mass flywheel and clutch are by far its weakest point, followed by the injectors, the EGR valve and, to a lesser extent, the turbo hoses and the timing drive itself.^{[8][9][10][11]}
