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 1.6 / 2.2 i-DTEC reliable?

The i-DTEC is Honda's diesel family from 2008, with two four-cylinder blocks: the 2.2 (Accord, CR-V) and, from 2013, the 1.6 (Civic, CR-V, HR-V). It uses a timing chain instead of a belt and common-rail injection. The basic architecture has a good reputation for longevity, but the emissions system (DPF and EGR) and the turbocharger account for most of the faults documented by owners themselves.[10][11][12][13]
