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 1.4 D-4D reliable?

Yes, generally: the 1.4 D-4D (1ND-TV) is one of Toyota's most widespread small diesels, with a reputation for reasonable reliability. The documented weak points are the injectors, the turbo, the EGR valve, the diesel particulate filter (on versions that have one) and the clutch and dual-mass flywheel assembly, with cases spread between 2002 and 2018 across the Yaris, Corolla, Auris, Urban Cruiser, Verso-S and MINI One D.^{[5][6][7][8][9]}
