2.0 HDi vs 1.7 CDTI: which engine is more reliable?

According to our risk index, the 1.7 CDTI carries less risk than the 2.0 HDi: 36/100 (moderate risk) versus 55/100 (high risk). The 2.0 HDi has 2 documented serious faults, the main one being «Variable-geometry turbo failures (actuator, sensors and clogging)»; the 1.7 CDTI has 3 documented serious faults, the main one being «Dual-mass flywheel and clutch wear».

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 1.7 CDTI reliable?

The 1.7 CDTI (Isuzu, 2003-2015) is a simple, widely used diesel, but it has built up accounts of soot-fouled EGR valves and injectors, a clogged diesel particulate filter (DPF) with oil dilution, wear of the dual-mass flywheel and clutch, and of the Hitachi-brand alternator; it also requires the timing belt to be changed every 150,000 km or 6 years to avoid a serious failure.^{[5][6][7][8][9][10][11]}
