Is the 1.9 JTD/Multijet and 2.4 JTD reliable?

The 1.9 JTD/Multijet (8v and 16v) and the five-cylinder 2.4 JTD were the world's first common rail diesels and have a reputation for robust, long-lived mechanicals. Before buying, check the known faults: the intake manifold flaps and the EGR valve fail or clog with urban use, the turbo and dual-mass flywheel wear with mileage, and the particulate filter on versions that have one clogs if there are not enough long journeys.^[1][2][3][4]

Is the 2.2 TD4 / SD4 reliable?

This is the 2.2-litre diesel of the Freelander 2, the first Evoque, the 2014-2015 Discovery Sport and the Jaguar XF 2.2D. The sources consulted do not describe it as a problematic engine, but they point to three things: the EGR cooler, the DPF in urban use, and replacing the belt along with the water pump.^[5][6][7]
