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 1.9 TDI reliable?

It depends a lot on the version. The rotary pump (1996-2003, codes ALH and AGR among others) has a reputation for great durability. The unit injector system (1999-2010) improves performance and emissions, but has more documented faults: dual-mass flywheel, turbo, EGR valve and, above all in the 105 hp version, cases of broken big-end bearings.[5][6][7][8][9][10][11]
