1.4 HDi vs 2.2 HDi: which engine is more reliable?

According to our risk index, the 1.4 HDi carries less risk than the 2.2 HDi: 43/100 versus 48/100 (both moderate risk). The 1.4 HDi has 1 documented serious fault, the main one being «Timing belt and water pump»; 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 1.4 HDi reliable?

It is a small diesel that is generally reliable, but with a very well-documented weakness: the injectors tend to lose their seal over time and let diesel escape. The turbo and the EGR valve also fail on a noticeable minority of units, and there are isolated cases of the crankshaft damper pulley failing at very high mileages. The timing belt does not seem to cause more problems than on any diesel of its era if it is changed on time.^[1][2][3]

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.^[4][5][6][7]
