1.6 and 2.0 MultiJet II vs 1.9 dCi: which engine is more reliable?

According to our risk index, the 1.6 and 2.0 MultiJet II carries less risk than the 1.9 dCi: 52/100 versus 67/100 (both high risk). The 1.6 and 2.0 MultiJet II has 2 documented serious faults, the main one being «Saturated diesel particulate filter (DPF) from incomplete regenerations»; the 1.9 dCi has 3 documented serious faults, the main one being «Seizure and wear of the big-end bearings».

Is the 1.6 and 2.0 MultiJet II reliable?

The 1.6 and 2.0 MultiJet II are Fiat diesels with a solid mechanical base, but with known faults worth checking before you buy: the timing belt tensioner may need replacing before the official interval, the EGR valve clogs with urban use, the particulate filter becomes saturated if there are not enough long journeys, and the dual-mass flywheel and the occasional injector wear with mileage. There is no officially recognised recall campaign for these faults.^[1][2][3][4]

Is the 1.9 dCi reliable?

The 1.9 dCi (F9Q) was Renault's first common-rail diesel (1999) and powered a large part of its range, and those of Nissan and Volvo, for more than a decade. It has well-documented weak points: on versions of up to 120 hp built before 2005, the big-end bearings can seize and the turbo tends to degrade around 150,000 km; the injectors, the EGR valve and, on the 120 hp versions, the dual-mass flywheel also fail fairly often.^{[5][6][7][8][9]}
