Is the 1.8, 2.0 and 2.2 16v EW7/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]

Is the 2.3 VR5 (V5) reliable?

The 2.3-litre VR5 is a naturally aspirated five-cylinder with the timing chain at the rear of the engine. Gebrauchtwagenberater rates it as a buy with no known problems in the Golf IV, but in the Bora it warns that the chain sometimes stretches; AutoHints adds the coils and the plastic coolant parts as points to watch.[9][10][11][12]
