Is the 1.3 Multijet reliable?

The 1.3 Multijet is a reliable diesel in the basics, but it has a known weak point across all its brands: the timing chain and its tensioner can stretch or fail if oil changes are neglected, with a risk of serious damage. In urban use, the EGR valve, the particulate filter and the variable-geometry turbo add to the list.^[1][2][3][4]

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