Is the 1.5 BlueHDi reliable?

The 1.5 BlueHDi has a serious weak point in engines built from October 2017 to January 2023: the 7 mm chain linking the camshafts can stretch and break. Stellantis has recalled them and covers this fault for 10 years or 240,000 km; engines built up to August 2020 can also suffer AdBlue tank failures, with partial compensation from the manufacturer.[1][2][3][4]

Is the 2.0 TDI reliable?

It depends on the generation. The EA189 (2008-2015) is the dieselgate engine: it needed a software update and has a record of EGR, particulate filter, turbo and injection faults. The earlier pumpe-düse (unit injector) engine has oil pump failures, and on the EA288 and EA288 evo (from 2012) the known faults are minor: coolant leaks and the odd AdBlue tank.[5][6][7][8][9][10]
