1.3 Multijet vs 1.6 HDi: which engine is more reliable?

According to our risk index, the 1.3 Multijet carries less risk than the 1.6 HDi: 64/100 versus 71/100 (both high risk). The 1.3 Multijet has 4 documented serious faults, the main one being «Timing chain stretch and tensioner failure»; the 1.6 HDi has 2 documented serious faults, the main one being «Turbo failure through lack of lubrication (carbon deposits and union filter)».

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]

See the 5 of the 1.3 Multijet faults

Is the 1.6 HDi reliable?

It is an efficient diesel, but its 16-valve versions (2004-2011) have a serious weak point: the turbo is starved of lubrication by carbon deposits from the oil, often made worse by leaks at the injector washers. The 8V engines (from 2010) improved, although you need to watch the 2010-2011 belt and the injectors, and on the BlueHDi the AdBlue tank.[5][6][7][8][9][10][11][12][13]
