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 dCi reliable?

The post-2010 1.5 dCi engines, especially the 90 hp, have a good record. The Euro 3 and Euro 4 units (2001-2010) carry serious faults: big-end bearings that can wreck the engine, a Delphi pump that fills the injection system with metal filings and, in some 105/110 hp versions, a timing belt and dual-mass flywheel that fail early.[5][6][7][8]
