2.0 HDi vs 2.5 dCi YD25: which engine is more reliable?

According to our risk index, the 2.0 HDi carries less risk than the 2.5 dCi YD25: 55/100 versus 59/100 (both high risk). The 2.0 HDi has 2 documented serious faults, the main one being «Variable-geometry turbo failures (actuator, sensors and clogging)»; the 2.5 dCi YD25 has 3 documented serious faults, the main one being «Timing chain wear and failure».

Is the 2.0 HDi reliable?

It is a robust diesel in its simplest 90 hp version, but the 136 to 140 hp generation with a DPF (2004-2011) concentrates the engine's problems: turbo, DPF, EGR and, above all, a dual-mass flywheel that fails very often. The BlueHDi engines (from 2013) are mechanically more reliable, but add an AdBlue tank that can crystallise; the OCU (Spanish consumer organisation) has reported this fault in Spain and Stellantis covers it with a compensation programme.[1][2][3][4]

Is the 2.5 dCi YD25 reliable?

The 2.5 dCi YD25 in the Navara D40 and Pathfinder R51 is tough, but it has one documented weak point: the lower timing chain, whose failure can destroy the engine. Check its condition, as well as the EGR and the turbo.[5][6][7]
