Is the 2.0 and 2.2 16v EW10/EW12 reliable?

The EW10 (2.0) and EW12 (2.2) are naturally aspirated 16-valve petrol engines with a timing belt, which PSA fitted between 1999 and 2010 to the 206, 307, 406, 407, 607, 807, C4, C5 and C8, among others. According to owners there are no frequent internal failures: the most-cited problems are the ignition coils (the only fault also reported by the press), the exhaust and, on the 2.2, oil consumption.^{[1][2][3][4][5][6][7][8]}

See the of the 2.0 and 2.2 16v EW10/EW12 fault

Is the 1.0 MPI reliable?

The 1.0 MPI is a simple, low-powered (60-75 hp) naturally aspirated three-cylinder engine with no serious or systemic faults documented. Its most frequently cited issues are above-normal oil consumption -- especially in the Seat Ibiza V -- and, more occasionally, a cooling system fault with the engine light and vibrations. The timing belt has no fixed replacement interval and shows no failure pattern.^{[9][10][11][12]}
