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.^[1][2][3]

Is the 1.9 dCi reliable?

The 1.9 dCi (F9Q) was Renault's first common-rail diesel (1999) and powered a large part of its range, and those of Nissan and Volvo, for more than a decade. It has well-documented weak points: on versions of up to 120 hp built before 2005, the big-end bearings can seize and the turbo tends to degrade around 150,000 km; the injectors, the EGR valve and, on the 120 hp versions, the dual-mass flywheel also fail fairly often.^{[4][5][6][7][8]}
