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 s…
Production years 1994–2006 meet Euro 2 standards . 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 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.
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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 8140.43S engine is renowned for its mechanical durability and longevity, often exceeding 300,000 km with proper care. Its main weakness is the Bosch VE injection pump, which is highly sensitive to fuel quality. With strict adherence to using high-quality diesel and changing the oil every 10,000 km, the engine can be extremely reliable. Neglecting fuel quality will almost certainly lead to expensive pump repairs.
The most frequent issues are Bosch VE injection pump failure, turbocharger oil seal leaks, glow plug or relay failure, and cylinder head gasket failure. These are well-documented in PSA service bulletins and owner reports. The injection pump issue is the most critical, as it can leave the vehicle stranded.
The 8140.43S (F28DTCR) 2.8L diesel engine was used in the Peugeot J5 van (1994-2006) and its badge-engineered siblings, the Citroën C25, Fiat Ducato, and Lancia Zeta. It was not used in any Peugeot passenger cars, being reserved for commercial and utility vehicles.
Yes, but it's mechanically complex. Power gains are achieved by modifying the Bosch VE pump (adjusting fuel screw and boost compensator) and upgrading the turbocharger. Gains of 20-30 kW are possible. However, this puts additional stress on engine components not designed for higher outputs. It's a popular modification in off-road and overlanding communities.
Fuel economy is typical for a large, old-school diesel van. Expect around 12.0 L/100km (24 mpg UK) in city driving and 9.0 L/100km (31 mpg UK) on the highway. Combined figures are usually around 10.5-11.0 L/100km (25-27 mpg UK), heavily dependent on vehicle weight, condition, and driving style.
No. The 8140.43S (F28DTCR) is a non-interference engine. If the timing gears were to fail, the pistons would not contact the valves, preventing catastrophic internal engine damage. This is a key safety feature of its robust, simple design.
Peugeot specifies an oil meeting the ACEA E2 standard, typically a 15W-40 mineral or semi-synthetic diesel engine oil. This specification is designed for older, high-compression diesel engines without advanced emissions systems. Using modern low-ash (C-series) oils is not recommended for this engine.
