2.2 16v 158-163 hp (EW12J4, 3FZ/3FY, 1999-2010) engine: faults and reliability

PSA 2.0 16v EW10 and 2.2 16v EW12 (gasolina, 1999-2010) version

With caution

Oil consumption is what comes up most in owner reviews of the 2.2 (10 of 56 according to the Fiches-auto.fr table, 5 of them in the 407 2.2, although in the 407 at least one testimony refers to the steering oil rather than the engine). It is a small sample with no independent second source, so it is worth measuring oil consumption and demanding proof of the last timing belt replacement.[1][2][3][4][5]
