Is the 2.0 BlueHDi reliable?

The 2.0 BlueHDi is mechanically one of the sturdiest PSA/Stellantis diesels: in the samples available for its 150 to 180 hp versions, the turbo, DPF, EGR and injectors fail noticeably less often than on earlier generations of the same engine from before 2013. Its documented weak point is the AdBlue tank, a fault so widespread that Stellantis compensates affected owners without a definitive fix.^[1][2][3][4]

Is the 2.2 dCi and 3.0 dCi V6 reliable?

Renault's big 2000s diesels, the 2.2 dCi (G9T) and the 3.0 V6 dCi (P9X), have a poor reputation among owners: big-end bearing failures are cited on the 2.2 and overheating on the V6. The sources are mainly forums and the press that reports them, with no official statistics.^[5][6][7]
