Citroën C8 problems (2002–2014)

We have documented 2 engines for the Citroën C8; the 2.2 HDi has high or critical severity faults. The safest option is the 2.0 and 2.2 16v EW10/EW12 in the 2.0 16v 136 hp (EW10J4, RFN/RFR, 1999-2005) and 2.0 16v VVT 140-143 hp (EW10A, RFJ, 2004-2011) versions, with a «Buy» verdict. Outside the engine, the Citroën C8 has no known recalls; owners cite electric side doors, tyre wear, rear electric windows and electronic faults, mainly on the earliest cars.

Among the 2 engines we have documented, the safest option is the 2.0 and 2.2 16v EW10/EW12 in the 2.0 16v 136 hp (EW10J4, RFN/RFR, 1999-2005) and 2.0 16v VVT 140-143 hp (EW10A, RFJ, 2004-2011) versions, with a «Buy» verdict. It is the simplest 2.0 (no variable valve timing or direct injection) and owner reviews of the 206, 406, Xsara Picasso and 307 point to wear parts - coils, lambda sensors, catalytic converter or manifold - rather than internal failures; gebrauchtwagenberater.de describes the 307's petrol engines as simple and easy to maintain.^{[1][2][3][4][5][6]}

Outside the engine, the Citroën C8 has no known recalls; owners cite electric side doors, tyre wear, rear electric windows and electronic faults, mainly on the earliest cars. The most important documented faults are: electric sliding side door failure on the C8 (bodywork and interior, medium severity), repeated electronic faults in the BSI control unit and wiring (electronics and infotainment, medium severity), premature tyre wear caused by the front axle geometry (tyres and wheels, low severity) and failure of the rear electric windows and their switches (electrical system, low severity).^[10][11]

The most important by severity and frequency, on the engines we have documented, are: DPF clogging with additive, especially on the 128-138 hp version (2.2 HDi, high severity), turbo faults, somewhat more frequent on the sequential twin-turbo versions (2.2 HDi, high severity), piezo injector wear and failure (2.2 HDi, high severity), faulty ignition coils (2.0 and 2.2 16v EW10/EW12, medium severity) and dual-mass flywheel wear, less frequent than on other HDi engines (2.2 HDi, medium severity).

According to our rating by year, the best are 2014, 2013, 2012 and 1 other years with the same rating (7.8/10); the worst rated is 2002 (7.2/10). Each year's rating counts only the engines sold that year and the faults that affect those units: open each year to see what changes.
