Is the TDV6 / SDV6 reliable?

The Land Rover and Jaguar TDV6/SDV6 diesel V6 engines, shared with Peugeot and Citroën, have a serious documented fault: crankshaft and main bearing shells on the 3.0, and the belt-driven oil pump on the 2.7. Insist on a service history and weigh up the repair cost before buying.^[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]
