2.2 HDi vs 1.9 TDI: which engine is more reliable?

According to our risk index, the 2.2 HDi carries less risk than the 1.9 TDI: 48/100 (moderate risk) versus 66/100 (high risk). The 2.2 HDi has 3 documented serious faults, the main one being «DPF clogging with additive, especially on the 128-138 hp version»; the 1.9 TDI has 3 documented serious faults, the main one being «Big-end bearing failure».

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.^[1][2][3][4]

Is the 1.9 TDI reliable?

It depends a lot on the version. The rotary pump (1996-2003, codes ALH and AGR among others) has a reputation for great durability. The unit injector system (1999-2010) improves performance and emissions, but has more documented faults: dual-mass flywheel, turbo, EGR valve and, above all in the 105 hp version, cases of broken big-end bearings.^{[5][6][7][8][9][10][11]}
