Injectors Volvo: problems by model and engine

Documented faults, from most to least important

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

- High severityFrequency: Common1.9 dCiFailures of the Delphi direct-injection injectorsThe Delphi injectors on the 1.9 dCi give trouble with some regularity, a weak point that gebrauchtwagenberater.de and planeterenault document as typical of direct-injection diesels of that era.
In S40 I and V40 I
- 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
In C30, S40 II, V40 II and V50
- 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.
In C30 and V40 II
- Medium severityFrequency: OccasionalDrive-E gasolinaCarbon build-up on injectors and intake valves due to direct injectionYes: as with other direct-injection engines, the Drive-E's injectors and intake valves accumulate carbon over time, with possible loss of power and rough idling. Two used-car analyses (Volvo XC40 and V90) flag it as a known weak point of this engine.
