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 1.2 TDI reliable?

A three-cylinder diesel with a single homologated output (75 hp) that Volkswagen fitted to the low-consumption versions of its smallest models between 2009 and 2014. It belongs to the EA189 family and was added to the list of engines in the emissions scandal a few days later. Its timing belt also drives the water pump and the high-pressure pump, so do not put off replacing it; also keep an eye on the turbo, the EGR and the particulate filter.[5][6][7][8]
