The Fiat 8140.47R is a 2,798 cc, inline‑six turbo‑diesel engine produced between 1998 and 2006. It features direct injection, a fixed — geometry turbocharger, and overhead camshaft design. In standard form, it delivered 92 kW (125 PS) and 285 Nm of torque, providing strong low — rpm torque for everyday drivability in commercial applications.
Fitted to models such as the Ducato, Scudo, and Ulysse vans and MPVs, the 8140.47R was engineered for durability and consistent per…
Production years 1998–2006 meet Euro 2 standards; some 2004–2006 models may have early Euro 3 compliance depending on market .
The Fiat 8140.47R is a 2,798 cc inline‑six turbo‑diesel engineered for light commercial vehicles and MPVs (1998-2006). It combines direct injection with a fixed‑geometry turbocharger to deliver robust low‑end power and towing capability. Designed to meet Euro 2 (and some market‑specific early Euro 3) standards, it prioritizes reliability for fleet and trade use.

The Fiat 8140.47R was used across Fiat's light commercial platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Ducato and specific cooling packages for the Ulysse-and from 2004 received minor ECU updates for emissions, creating minor software 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 8140.47R is fundamentally robust, with a gear-driven timing system offering exceptional longevity. Its main weakness is the Bosch VP47 injection pump, which is prone to failure with poor maintenance. With strict adherence to fuel filter changes and use of quality diesel, a well-maintained 8140.47R can easily exceed 300,000 km.
The most frequent and critical issue is failure of the Bosch VP44 injection pump. Other common problems include turbocharger oil seal leaks, glow plug/relay failures causing cold-start issues, and coolant leaks from the water pump or aging hoses. These are well-documented in Fiat service bulletins.
This 2.8L diesel was primarily used in Fiat's commercial and MPV lineup from 1998-2006, including the Ducato, Scudo, and Ulysse. It was also shared with PSA Group vehicles, appearing in the Citroën Jumpy and Peugeot Expert of the same era as the 2.8 HDi.
Yes, but with significant caveats. The VP44 pump can be recalibrated or replaced with higher-output units, yielding modest gains. However, the engine's internals and clutch are not designed for high stress. Aggressive tuning significantly increases the risk of pump failure and is generally not recommended for longevity.
Fuel economy is moderate for its size and era. In a Ducato van, expect approximately 9.5-11.0 L/100km (25-28 mpg UK) combined, depending on load and driving style. In lighter MPVs like the Ulysse, figures may improve to 8.5-10.0 L/100km (28-33 mpg UK).
No. The Fiat 8140.47R is a non-interference engine. This means if the timing gears were to fail (an extremely rare event), the pistons would not contact the valves, preventing catastrophic internal damage. This is a major design advantage for longevity.
Fiat specifies an oil meeting ACEA B3/B4 standards, typically a 15W-40 viscosity for normal operating conditions. Using the correct specification is crucial to protect the injection pump and turbocharger. Oil should be changed every 20,000 km or 12 months, whichever comes first.
