Is the 2.2 i-CTDi reliable?

The 2.2 i-CTDi is the diesel Honda fitted to the Civic, Accord, CR-V and FR-V in Europe between 2003 and 2011, before the i-DTEC. It uses a timing chain and common-rail injection, an architecture that generally ages well. The best-documented faults are wear of the dual-mass flywheel and clutch, and cracks in the exhaust manifold; there are also cases involving the turbo, EGR and injectors.[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]
