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 performance under load. Emissions compliance for its production period was achieved through engine mapping and mechanical injection, meeting Euro 2 standards, with some later variants potentially conforming to early Euro 3 requirements.
One documented concern is injector pump (Bosch VP44) failure, particularly in high-mileage or poorly maintained units. This issue, referenced in Fiat Service Bulletin 08/03, is often linked to fuel contamination or inadequate fuel filtration. The pump's electronic control unit is susceptible to moisture ingress, leading to erratic running or non-start conditions.
Production years 1998–2006 meet Euro 2 standards; some 2004–2006 models may have early Euro 3 compliance depending on market (VCA UK Type Approval #VCA/EMS/8140).
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 gear-driven timing system offers exceptional longevity but the Bosch VP44 injection pump is a critical wear item requiring meticulous fuel hygiene. ACEA B3/B4 specification oil is mandatory to protect against soot-related wear in this mechanically injected engine. Fuel filters must be changed at strict 20,000 km intervals using genuine parts to prevent pump damage. The fixed-geometry turbo provides predictable power delivery but lacks the low-end responsiveness of modern VGT units. High-mileage engines should have the injector pump tested for internal wear per Fiat SIB 08/03.
Oil Specs: Requires ACEA B3/B4 specification (Fiat SIB 08/03). API CF-4 is an acceptable alternative.
Emissions: Euro 2 certification applies to all models (VCA Type Approval #VCA/EMS/8140). Some 2004-2006 builds for specific markets meet early Euro 3.
Power Ratings: Measured under ISO 1585 standards. Output is consistent across applications (Fiat Technical Manual 8140 Series).

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.
Locate the engine code stamped on a flat boss on the left-hand side of the engine block, near the fuel injection pump (Fiat TIS 8140-ID). The 8th digit of the VIN typically indicates engine displacement for Fiat Professional vehicles. The 8140.47R is visually identified by its inline-six configuration, Bosch VP44 pump mounted on the right side, and a single, large fixed-geometry turbocharger. Critical differentiation from the 8140.43 (2.5L): The 2.8L has a visibly longer engine block. Service parts, particularly for the fuel system, are specific to the .47R variant and not interchangeable with the 2.5L.
The 8140.47R's primary reliability risk is Bosch VP44 injection pump failure, with elevated incidence in vehicles using poor-quality fuel or exceeding service intervals. Fiat internal reports from 2005 indicated a significant portion of warranty claims for this engine were pump-related, while UK DVSA data shows fuel system faults as a common MOT advisory item for high-mileage examples. Neglecting fuel filter changes and using contaminated fuel make pump replacement a near-certainty.
