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 2.0 Ingenium diésel reliable?

The 2.0 Ingenium diesel is the four-cylinder diesel engine that Jaguar Land Rover designed from scratch and has fitted since 2015 to the Range Rover Evoque, the Discovery Sport and several Jaguars. Several sources repeatedly document timing chain stretch, balance shaft wear, turbo failures and fuel dilution of the oil, so it is worth checking thoroughly before buying.^[10][11]
