1.6 TDI vs 2.2 MultiJet / BlueHDi (Stellantis): which engine is more reliable?

According to our risk index, the 2.2 MultiJet / BlueHDi (Stellantis) carries less risk than the 1.6 TDI: 14/100 (low risk) versus 45/100 (moderate risk). The 1.6 TDI has 2 documented serious faults, the main one being «Timing belt and water pump»; the 2.2 MultiJet / BlueHDi (Stellantis) has 1 documented serious fault, the main one being «Unvulcanised fuel return pipe: fuel leak and fire risk».

Is the 1.6 TDI reliable?

It depends on the generation. The EA189 (2009-2015, 75-105 hp) is one of the dieselgate engines: it needs the software update and, unlike the 2.0 TDI, an air flow stabiliser, on top of the typical EGR, particulate filter and turbo faults. The later EA288 (from 2012, 80-120 hp) is not singled out by the scandal, but it shares the need to keep an eye on the timing belt and the water pump.^[1][2][3][4]

Is the 2.2 MultiJet / BlueHDi (Stellantis) reliable?

The 2.2 diesels of Stellantis's large vans (BlueHDi DW12 in the Boxer, Jumper and Movano; Multijet 3 in the Ducato) are recent engines with no fault statistics of their own. What is documented are campaigns: AdBlue and SCR software, and the fuel return pipe on 2024-2025 units, with a fire risk. Long-term history is missing.^{[5][6][7][8][9]}
