Injectors Fiat: problems by model and engine

Documented faults, from most to least important

Severity × frequency. Below each one, the Fiat models it appears in.

- High severityFrequency: Occasional1.3 MultijetInjector and high-pressure pump wear from contaminated fuelThe Bosch injectors and the high-pressure pump of the common rail system are sensitive to poor-quality fuel or fuel with condensed water. With contaminated diesel they can generate metal shavings that damage first the pump and then the injectors themselves.Repair (garage): €600–€1,200
In 500, 500L, 500X, Doblò II, Panda III and Punto III and 2 more models
- Medium severityFrequency: Occasional1.6 and 2.0 MultiJet IIInjector faults and DPF particulate sensor failureIn some batches, a fault in the injection system or in the DPF particulate sensor turns on the engine fault warning light. In the Fiat Doblò, worn injectors or injectors with poor atomisation are also cited as a cause of power loss, higher consumption and black smoke when accelerating.
In 500L, 500X, Bravo, Doblò II, Freemont and Tipo
- Medium severityFrequency: Occasional2.4 JTD / JTDm MultijetInjector failure and diesel leaks on the 2.4 JTDmThere are injector failures on the 2.4 JTDm: 9 mentions in 163 testimonies for the Alfa 156 and 159. A 2008 210 hp lost five injectors one after another at 93,000 km, with diesel leaks, and Fiat's 2007 action on the 200 hp replaced all the injectors.

- Medium severityFrequency: Occasional2.3 MultiJetLeaking or underperforming common-rail injectorsThere are signs of leaking or underperforming injectors on the 2.3: a French sheet on the Daily IV cites leaks at the injector wells and a 2021 British campaign for the 2016-2019 Daily replaces the filter and checks the injectors. Reliable statistics are lacking and there is no campaign for the Ducato.
