Is the 1.6 and 2.0 MultiJet II reliable?

The 1.6 and 2.0 MultiJet II are Fiat diesels with a solid mechanical base, but with known faults worth checking before you buy: the timing belt tensioner may need replacing before the official interval, the EGR valve clogs with urban use, the particulate filter becomes saturated if there are not enough long journeys, and the dual-mass flywheel and the occasional injector wear with mileage. There is no officially recognised recall campaign for these faults.[1][2][3][4]

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.[5][6][7]
