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 1.8/2.2 DI-D reliable?

Yes, in general: Mitsubishi's own 1.8 DI-D (4N13) and 2.2 DI-D (4N14) diesels have a reputation for reliability compared with the Volkswagen and PSA engines they replaced in 2010. Their best-documented fault is a clogged particulate filter with oil dilution on short journeys, along with occasional cases of injector, turbo and balance shaft problems. Do not confuse them with the PSA 2.2 HDi that the Outlander used earlier, shared with the C-Crosser and the Peugeot 4007.^[4][5][6][7]
