1.6 / 2.2 i-DTEC vs 2.2 HDi: which engine is more reliable?

According to our risk index, the 2.2 HDi carries less risk than the 1.6 / 2.2 i-DTEC: 48/100 (moderate risk) versus 54/100 (high risk). The 1.6 / 2.2 i-DTEC has 3 documented serious faults, the main one being «Turbocharger failure»; 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 1.6 / 2.2 i-DTEC reliable?

The i-DTEC is Honda's diesel family from 2008, with two four-cylinder blocks: the 2.2 (Accord, CR-V) and, from 2013, the 1.6 (Civic, CR-V, HR-V). It uses a timing chain instead of a belt and common-rail injection. The basic architecture has a good reputation for longevity, but the emissions system (DPF and EGR) and the turbocharger account for most of the faults documented by owners themselves.^[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]
