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.[1][2][3][4]

Is the TDV6 / SDV6 reliable?

The Land Rover and Jaguar TDV6/SDV6 diesel V6 engines, shared with Peugeot and Citroën, have a serious documented fault: crankshaft and main bearing shells on the 3.0, and the belt-driven oil pump on the 2.7. Insist on a service history and weigh up the repair cost before buying.[5][6][7]
