1.5 dCi vs 2.4 / 2.8 D-4D (GD): which engine is more reliable?

According to our risk index, the 2.4 / 2.8 D-4D (GD) carries less risk than the 1.5 dCi: 20/100 (low risk) versus 63/100 (high risk). The 1.5 dCi has 4 documented serious faults, the main one being «Wear and seizure of the big-end bearings»; the 2.4 / 2.8 D-4D (GD) has no documented serious faults.

Is the 1.5 dCi reliable?

The post-2010 1.5 dCi engines, especially the 90 hp, have a good record. The Euro 3 and Euro 4 units (2001-2010) carry serious faults: big-end bearings that can wreck the engine, a Delphi pump that fills the injection system with metal filings and, in some 105/110 hp versions, a timing belt and dual-mass flywheel that fail early.[1][2][3][4]

Is the 2.4 / 2.8 D-4D (GD) reliable?

No serious mechanical faults are documented in the European sources we were able to open: AutoBild saw the 2.8 as more robust than the 3.0 it replaced, although it points to glow plugs that fail early. Its best-documented weak point is the particulate filter, with a lawsuit in Australia but no equivalent recall or legal action in Europe, and there are barely any high-mileage examples from which to judge long-term reliability.[5][6][7]
