1.6 HDi 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 HDi: 48/100 (moderate risk) versus 71/100 (high risk). The 1.6 HDi has 2 documented serious faults, the main one being «Turbo failure through lack of lubrication (carbon deposits and union filter)»; 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 HDi reliable?

It is an efficient diesel, but its 16-valve versions (2004-2011) have a serious weak point: the turbo is starved of lubrication by carbon deposits from the oil, often made worse by leaks at the injector washers. The 8V engines (from 2010) improved, although you need to watch the 2010-2011 belt and the injectors, and on the BlueHDi the AdBlue tank.[1][2][3][4][5][6][7][8][9]

See the 7 of the 1.6 HDi faults

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.[10][11][12][13]
