The Iveco 552 80 444 is a 3,496 cc, inline-four turbo-diesel engine produced between 2020 and 2025. It features high-pressure common-rail injection (up to 1,800 bar), a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), delivering 162 kW (220 PS) and 500 Nm of torque. This engine was engineered for light commercial vehicle applications requiring maximum low-end pull and improved responsiveness over earlier variants.
Fitted to models including the Iveco Daily (50C) and various OEM derivatives, the 552 80 444 was designed to balance high payload capability with urban fuel economy. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 6d standards across its production run.
One documented concern involves intermittent AdBlue dosing valve crystallization, particularly in vehicles operating under frequent cold-start conditions. This issue, referenced in Iveco Service Information Bulletin 552-288, is attributed to incomplete heating cycles and low-quality AdBlue fluid. From 2022, revised dosing valve materials and updated thermal management logic were implemented to improve system durability.
Production years 2020–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9123).
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 high-torque, low-RPM design provides excellent pulling power for loaded vans but requires strict adherence to 20,000 km oil change intervals using Iveco 9.55535-S4 (5W-30) to protect the DPF and turbocharger. Use of EN 590-compliant diesel is critical to prevent fuel system wear. Urban delivery cycles increase EGR and DPF soot loading; regular highway runs support passive regeneration. Post-2022 models benefit from updated ECU logic that reduces low-load carbon buildup. DPF regeneration faults may trigger limp mode; forced regeneration via diagnostic tool is often required.
Oil Specs: Requires Iveco 9.55535-S4 (5W-30) specification (Iveco SIB 552-288). Replaces ACEA E9 standards.
Emissions: Euro 6d certification applies to all 2020–2025 models (VCA Type Approval #VCA/EMS/9123).
Power Ratings: Measured under UN ECE Regulation 85. Output consistent across fuel qualities meeting EN 590.

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.
Locate the engine code stamped vertically on the left-side engine block near the oil pan rail (Iveco TIS A552-2489). The 8th VIN digit indicates engine type ('L' for 2.3 Multijet 220 HP). Pre-2022 models have silver valve covers with black cam belt covers; post-2022 units use all-black covers. Critical differentiation from earlier 2.3 HPI: The 552 80 444 uses common-rail injection and a Garrett GT1749V turbo, while pre-2020 units use unit injectors and smaller turbos. Service parts require model-year verification—EGR coolers for pre-2022 models are not interchangeable due to revised flow paths (Iveco SIB 552-288).
The 552 80 444's primary reliability risk is AdBlue dosing system failure, with elevated incidence in cold-climate urban delivery vehicles. Internal Iveco field reports from 2023 indicated over 20% of northern European units required dosing valve replacement before 150,000 km, while UK DVSA MOT data shows SCR-related failures are common in stop-start conditions. Cold-start cycles and low-quality AdBlue accelerate crystallization, making fluid quality and thermal management critical.
