Injectors Citroën: problems by model and engine

Documented faults, from most to least important

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

- Medium severityFrequency: Very frequent1.4 HDiInjectors that lose their seal and let diesel escapeThe most cited weak point of the 1.4 HDi is its injectors: over time they can lose their seal and let diesel escape, which is usually noticed as a smell of diesel in the car. It appears in the two most common outputs (68 and 70 hp) and in both cases it is identified as the engine's main weakness.
In C1 I, C2, C3 I and C3 II
- High severityFrequency: Occasional2.2 HDiPiezo injector wear and failureThe 2.2 HDi uses third-generation common-rail injection with piezo injectors at up to 1,800-2,000 bar. Fiches-auto documents injector cases across several power outputs, without it being the most repeated fault, with symptoms of hard starting, jerking or higher fuel consumption.
In C-Crosser, C5 I, C5 II, C6 and C8
- High severityFrequency: Occasional2.0 BlueHDiInjector and high-pressure pump wearThe injectors and the high-pressure pump on the 2.0 BlueHDi are among the documented faults, although in a minority of the cases recorded compared with AdBlue or the DPF. When the pump fails, metal particles can contaminate the whole circuit and make the repair far more expensive.
In C4 Picasso II, C5 Aircross and Jumpy III
- Medium severityFrequency: Common1.6 HDiLeaks at the injector washers and carbon build-up in the cylinder headIt is common for the copper washers of the 1.6 HDi injectors to stop sealing: the engine blows gases, carbon forms around the injector and soot gets into the oil. It is cheap to repair, but if left it contaminates the oil and is one of the causes of turbo failure.Repair (garage): €110–€310

- Medium severityFrequency: Common1.6 HDiJerking and injection faults on the 1.6 e-HDi 112/115 (Continental injectors)The 112 and 115 hp 1.6 HDi/e-HDi built between late 2011 and February 2014 can jerk and turn on the engine warning light because of an internal electrical defect in their Continental injectors. PSA covered their replacement depending on age and mileage.

- Medium severityFrequency: Occasional2.2 / 2.4 / 3.2 TDCi (Puma)Faulty injectors on the 2.2 and 2.4 TDCiHaynes documents faulty injectors on the 115 hp Transit 2.2 and the 140 hp 2.4, and L'argus reports an injector recall on the 2014-2015 Boxer and Jumper 2.2 HDi. They cause rough idle, loss of power or stalling.
