2.2 HDi vs 2.5 / 3.0 D-4D (KD): which engine is more reliable?

According to our risk index, the 2.2 HDi carries less risk than the 2.5 / 3.0 D-4D (KD): 48/100 (moderate risk) versus 63/100 (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 2.5 / 3.0 D-4D (KD) has 3 documented serious faults, the main one being «Cracked pistons in the 3.0 D-4D (1KD-FTV)».

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 2.5 / 3.0 D-4D (KD) reliable?

Toyota's KD diesels (2.5 D-4D, 2KD-FTV, and 3.0 D-4D, 1KD-FTV) have their best-documented weak points in the injectors: the copper seats of the 2004-2007 units, which can block the oil pickup, and the Denso injectors of the 3.0. The 3.0 of the Euro 4 era also has a record of cracked pistons; for the 2.5 we have only found the injector seal problem.[5][6][7][8][9]
