Is the 1.6 HDi reliable?

It is an efficient diesel, but its 16-valve versions (2004-2011) have a serious weak point: the turbo is starved of lubrication by carbon deposits from the oil, often made worse by leaks at the injector washers. The 8V engines (from 2010) improved, although you need to watch the 2010-2011 belt and the injectors, and on the BlueHDi the AdBlue tank.[1][2][3][4][5][6][7][8][9]

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.[10][11][12]
