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 VM Motori 2.8 and 3.0 CRD reliable?

The VM Motori 2.8 CRD (four-cylinder) and 3.0 CRD V6 diesels from Jeep, Chrysler and Lancia show no systemic fault in open sources: they describe injector wear, a dirty EGR and a high-mileage turbo, and AUTO BILD says durability complaints about the 3.0 are very rare. The UK DVSA identifies only one engine campaign for the 3.0 (2025).^[4][5][6][7]
