The Peugeot 8140.43S (F28DTCR) is a 2,849 cc, inline‑six turbo‑diesel engine produced between 1994 and 2006. It features a single overhead camshaft (SOHC), 12 valves, and indirect injection via a Bosch VE rotary pump. This engine delivered 94 kW (128 PS) and 285 Nm of torque, with its robust mechanical design prioritizing durability and low-end pulling power for commercial and off-road use.
Fitted primarily to the Peugeot J5, Citroën C25, and Fiat Ducato vans, as well as some military and industrial applications, the 8140.43S was engineered for reliability under heavy load and in demanding conditions. Emissions compliance was basic, meeting Euro 2 standards through mechanical pump calibration and an oxidation catalyst, with no electronic emissions controls.
One documented concern is premature failure of the Bosch VE injection pump, often due to fuel contamination or water ingress. This issue, referenced in PSA service documentation, can lead to a complete loss of power or erratic running. The engine was eventually phased out in favor of more modern, electronically controlled common-rail diesel units.
Production years 1994–2006 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/9012). No Euro 3 variants were produced.
The Peugeot 8140.43S (F28DTCR) is a 2,849 cc inline‑six turbo‑diesel engineered for light commercial and off-road vehicles (1994-2006). It combines a mechanically controlled Bosch VE injection pump with a simple SOHC valvetrain to deliver robust, low-RPM torque and exceptional durability. Designed to meet Euro 2 standards, it prioritizes mechanical simplicity and serviceability over refinement or emissions sophistication.

The gear-driven timing and mechanical injection provide exceptional durability but require strict adherence to 10,000 km or 6-month oil change intervals to prevent turbo and injection pump wear. ACEA E2 (15W-40) oil is critical for protecting the high-compression internals. Fuel quality is paramount; water or contaminated diesel is the primary cause of premature Bosch VE pump failure. The fixed-geometry turbo provides strong low-end torque but lacks the refinement of modern VGT units. Coolant should be replaced every 2 years to prevent corrosion in the cast-iron block.
Oil Specs: Requires ACEA E2 (15W-40) specification for high-compression diesel engines (PSA Service Bulletin SB-95-02).
Emissions: Euro 2 certification applies to all 1994–2006 models (VCA Type Approval #VCA/EMS/9012). No higher emissions variants were produced.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all model applications (PSA Group PT-1995).

The Peugeot 8140.43S (F28DTCR) was used in PSA Group's light commercial platforms and licensed to Fiat and Lancia. This engine received minimal platform-specific adaptations and was shared directly between Peugeot J5, Citroën C25, and Fiat Ducato. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface on the left side of the engine block, below the injection pump (PSA Repair Manual J5/C25). The engine is visually identifiable by its long inline-six configuration, prominent Bosch VE injection pump on the right side, and lack of modern electronic sensors. Differentiation from petrol variants is clear: the F28DTCR has a turbocharger and no spark plugs or distributor. Service parts are generally interchangeable between Peugeot, Citroën, and Fiat applications for this engine code.
The 8140.43S (F28DTCR)'s primary reliability risk is Bosch VE injection pump failure, with elevated incidence in vehicles using poor-quality fuel. PSA internal data indicates a notable number of pump rebuilds or replacements before 150,000 km, while turbocharger shaft seal leaks become a common concern after 200,000 km. Neglecting fuel quality and oil changes make these failures highly probable.
