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 1.6 CDTI reliable?

The Opel/Vauxhall 1.6 CDTI (2013-2020, 95-160 hp) has no design fault acknowledged by the manufacturer, but it has built up reports of early wear of the timing chain and its tensioner, two episodes (2016 and 2018) of German investigation into a possible EGR valve shut-off, and AdBlue system faults on its Euro 6 versions.^{[4][5][6][7][8][9][10]}
