1.4 HDi 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 1.4 HDi: 20/100 (low risk) versus 43/100 (moderate risk). The 1.4 HDi has 1 documented serious fault, the main one being «Timing belt and water pump»; the 2.4 / 2.8 D-4D (GD) has no documented serious faults.

Is the 1.4 HDi reliable?

It is a small diesel that is generally reliable, but with a very well-documented weakness: the injectors tend to lose their seal over time and let diesel escape. The turbo and the EGR valve also fail on a noticeable minority of units, and there are isolated cases of the crankshaft damper pulley failing at very high mileages. The timing belt does not seem to cause more problems than on any diesel of its era if it is changed on time.[1][2][3]

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.[4][5][6]
