The Iveco 552 80 444 is a 3,496 cc inline-four turbo-diesel engineered for light-duty commercial vans and chassis cabs (2020–2025). It combines high-pressure common-rail injection with a variable geometry turbocharger to deliver robust low-RPM torque and reliable daily operation. Designed to meet Euro 6d standards, it balances payload performance with urban efficiency.

The Iveco 552 80 444 was used across Iveco's 50C platform with longitudinal mounting and shared architecture with Fiat and Peugeot variants. This engine received platform-specific adaptations—reinforced torque mounts in the Daily Van and extended oil coolers in chassis cab applications—and from 2022, updated ECU calibration for improved emissions control, creating minor service part distinctions. Partnerships within the FCA group allowed shared componentry across brands. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 552 80 444 offers strong low-end torque and efficiency, but long-term reliability depends heavily on usage and maintenance. Engines used for frequent short trips are prone to DPF and EGR issues. Regular oil changes with correct specification (5W-30 Iveco 9.55535-S4) and periodic highway driving to enable DPF regeneration significantly improve longevity. Well-maintained units can exceed 400,000 km in commercial service.
The most common issues are AdBlue dosing valve crystallization, DPF regeneration failure, and turbo actuator sticking. EGR clogging is also reported, particularly in stop-start delivery vehicles. These are documented in Iveco service bulletins, particularly SIB 552-288, which addresses dosing system revisions. Fluid quality and cold-start cycles are primary concerns in colder climates.
This engine was used in the Iveco Daily (50C) from 2020 to 2025, badged as 55C22/55S22. It was also shared across FCA platforms in the Fiat Ducato (250), Peugeot Boxer (250), and Citroën Jumper (250). All applications meet Euro 6d emissions standards, with minor ECU and cooling variations between models.
Aftermarket ECU tuning is common on the 55280444 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In combined driving, the Iveco Daily 55C22 achieves approximately 6.3 L/100km (45 mpg UK). Highway consumption can drop to 5.6 L/100km (50 mpg UK), while city driving may reach 7.6 L/100km (37 mpg UK). Real-world economy heavily depends on load and driving style, with poorly maintained units showing significantly higher consumption.
Yes, the 552 80 444 is an interference engine. If the timing chain fails or skips, piston-to-valve contact will occur, resulting in severe internal damage. However, the chain-driven system is generally robust when maintained with correct oil and intervals. Any unusual front-end rattle should be investigated immediately to prevent catastrophic failure.
The engine requires Iveco 9.55535-S4 specification oil, typically SAE 5W-30. This formulation is critical for EGR system cleanliness and turbocharger protection. Oil changes should be performed every 20,000 km or annually, whichever comes first. Using non-compliant oil increases the risk of sludge and carbon buildup, leading to premature component wear.
