Is the 1.5 dCi reliable?

The post-2010 1.5 dCi engines, especially the 90 hp, have a good record. The Euro 3 and Euro 4 units (2001-2010) carry serious faults: big-end bearings that can wreck the engine, a Delphi pump that fills the injection system with metal filings and, in some 105/110 hp versions, a timing belt and dual-mass flywheel that fail early.[1][2][3][4]

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.[5][6][7][8]
