1.7 CRDi vs 2.2 HDi: which engine is more reliable?

According to our risk index, the 1.7 CRDi carries less risk than the 2.2 HDi: 38/100 versus 48/100 (both moderate risk). The 1.7 CRDi has 2 documented serious faults, the main one being «Injectors that lose calibration with mileage»; 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 1.7 CRDi reliable?

The 1.7 CRDi (U2 D4FD, 2010-2018) is a reasonably reliable diesel if it is properly maintained, with one specific documented problem in cold weather: power loss and stalling caused by the turbo actuator, the diesel filter and the glow plugs. It also suffers the emissions-system wear (EGR, DPF) typical of its generation, injectors that can lose calibration and, in a particular mileage range, high-pressure pump failures.[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]
