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 D4/D5 reliable?

The Volvo D5/D4 covers two different engines: the classic 5-cylinder (2001-2016, D5244T/D5204) and the 4-cylinder VEA (D4204T, from 2013). On the former, several owners document the auxiliary belt breaking and taking the timing belt with it, destroying the engine; on the VEA the most common problems are the EGR, the DPF and oil consumption that can damage the turbo from 90,000-150,000 km. Neither is an engine to buy without checking its service history.^{[8][9][10][11]}
