2.2 HDi vs 2.3 dCi (M9T): which engine is more reliable?

According to our risk index, the 2.3 dCi (M9T) carries less risk than the 2.2 HDi: 32/100 versus 48/100 (both moderate 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 2.3 dCi (M9T) has 2 documented serious faults, the main one being «Clogged or broken EGR valve damaging the turbo».

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 2.3 dCi (M9T) reliable?

The 2.3 dCi M9T is a van diesel with good durability if maintenance is kept up. The weak points cited are the EGR and the turbo, the injectors, and the particulate filter in urban use; the sources are mostly opinion websites.[5][6]
