The Alfa Romeo 552 83 099 – Diesel is a 1,956 cc, inline — four turbo — diesel engine produced between 2016 and 2020. It belongs to the Fiat Global Small Engine (GSE) family, specifically the 2.0L JTDM — 3 generation, co — developed with FCA and PSA Group. Featuring Bosch CRS 3 — 20 common rail injection (up to 2,500 bar), variable geometry turbocharging (VGT), and DOHC 16 — valve layout, it delivers 121 kW (165 PS) and peak torque of 380 Nm, designed for responsive mid — range perform…
Production years 2016–2020 meet Euro 6c standards .
The Alfa Romeo 552 83 099 – Diesel is a 1,956 cc inline-four turbo-diesel engineered for premium sedans and SUVs (2016–2020). It combines high-pressure common-rail injection with a variable-geometry turbocharger to deliver strong mid-range torque and refined operation. Designed to meet Euro 6c standards, it integrates emissions control within the exhaust manifold, balancing performance with environmental compliance.

The Alfa Romeo 552 83 099 – Diesel was used across Alfa Romeo's 952/956 platforms with longitudinal mounting and shared with Fiat and Lancia under FCA Group collaboration. This engine received platform-specific adaptations—reinforced engine mounts in the Stelvio and revised intake manifolds in the Giulia—and from 2018 received updated ECU calibration and HPFP firmware, creating interchange limits. 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 83 099 – Diesel offers strong mid-range torque and Euro 6c compliance, but early models (2016–2017) are prone to HPFP calibration issues. Later revisions (post-2018) improved ECU synchronization and reduced cold-start hesitation. When maintained properly—using high-quality diesel and correct oil (5W-40 Fiat M2)—these engines can reliably exceed 180,000 km.
The most documented issues are HPFP calibration sensitivity, integrated SCR/DPF clogging, turbo actuator sticking, and oil leaks from valve cover gaskets. Calibration issues are especially prevalent in pre-2018 units with frequent cold starts. These concerns are addressed in Alfa Romeo Technical Bulletin 59 005 14 and routine service campaigns.
This 2.0L diesel was used in the Alfa Romeo Giulia (952) and Stelvio (956) from 2016 to 2020. It was also shared across FCA Group brands: Fiat Talento and Lancia Voyager. All applications met Euro 6c emissions standards during their production run.
Aftermarket ECU tuning is common on the 55283099 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 the Alfa Romeo Stelvio 2.0 JTDM-3, combined consumption is approximately 5.1 L/100km (~55 mpg UK). Real-world figures vary: city driving may see 6.5–7.0 L/100km, while highway runs can achieve 4.8–5.0 L/100km. Proper maintenance and use of quality diesel are essential for optimal economy.
Yes. The 552 83 099 – Diesel is an interference engine. If the timing chain fails or skips, piston-to-valve contact will occur, resulting in severe internal damage. The chain is maintenance-free per OEM, but early failure can happen due to oil starvation or poor lubrication, so oil changes must be strictly observed.
Alfa Romeo specifies Fiat 9.55535-S3 M2 (5W-40) synthetic oil. This formulation ensures proper lubrication for the high-pressure fuel pump and turbo bearings. Oil changes should be performed every 15,000 km or annually to maintain engine longevity and prevent fuel system wear.
