Is the 1.6 CRDi reliable?

The U2 D4FB (2009-2018) is a generally robust diesel if well maintained, with known turbo failures in the early units and timing chain problems from 120,000-150,000 km. Its successor, the Smartstream (U3 D4FE, from 2018), has a good reputation, except in the 48V mild hybrid version, which has a belt tensioner and crankshaft pulley fault that can destroy the engine.[1][2][3]

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.[4][5][6][7]
