1.9 JTD/Multijet and 2.4 JTD vs 2.2 HDi: which engine is more reliable?

The 1.9 JTD/Multijet and 2.4 JTD and the 2.2 HDi tie on our risk index: 48/100 (moderate risk). The 1.9 JTD/Multijet and 2.4 JTD has 2 documented serious faults, the main one being «Intake manifold flap failure (swirl effect)»; the 2.2 HDi has 3 documented serious faults, the main one being «DPF clogging with additive, especially on the 128-138 hp version».

Is the 1.9 JTD/Multijet and 2.4 JTD reliable?

The 1.9 JTD/Multijet (8v and 16v) and the five-cylinder 2.4 JTD were the world's first common rail diesels and have a reputation for robust, long-lived mechanicals. Before buying, check the known faults: the intake manifold flaps and the EGR valve fail or clog with urban use, the turbo and dual-mass flywheel wear with mileage, and the particulate filter on versions that have one clogs if there are not enough long journeys.^[1][2][3][4]

Is the 2.2 HDi reliable?

This is a diesel derived from the 2.0 HDi that PSA and Ford shared in large saloons and MPVs (407, 607, 807, C5, C6, C8) and that Land Rover and Ford used under their own names (TDCi, TD4, SD4) in the Mondeo IV, the Freelander 2 and the first Evoque. According to fiches-auto it does not suffer chronically from the turbo or dual-mass flywheel problems of smaller HDi engines, but the 128-138 hp version does have a recurring problem of DPF clogging.^[5][6][7][8]
