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 2.0 dCi reliable?

The 2.0 dCi (M9R) is a Renault-Nissan Alliance diesel with known, well-documented weak points: the turbo and the EGR valve fail relatively often, the particulate filter clogs up in urban use, and there are cases of injectors and even the timing chain failing earlier than expected in several of the models that use it.^[5][6][7][8]
