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 1.6 TDI reliable?

It depends on the generation. The EA189 (2009-2015, 75-105 hp) is one of the dieselgate engines: it needs the software update and, unlike the 2.0 TDI, an air flow stabiliser, on top of the typical EGR, particulate filter and turbo faults. The later EA288 (from 2012, 80-120 hp) is not singled out by the scandal, but it shares the need to keep an eye on the timing belt and the water pump.[5][6][7][8]
