The Renault 847 725 is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2006 and 2014. It features a high-pressure common-rail direct injection system with a variable geometry turbocharger (VGT) and a double overhead camshaft (DOHC) design. This iteration delivered 96 kW (130 PS) and 300 Nm of torque, offering a significant improvement in power and refinement over its 1.9L predecessor.
Fitted to the Renault Trafic II (Phase 2) and Master II vans, along with their badge-engineered counterparts like the Opel/Vauxhall Vivaro C and Nissan Primastar, the 847 725 was engineered for enhanced performance and lower emissions while maintaining the durability expected in commercial applications. Emissions compliance for its production period was met through an exhaust gas recirculation (EGR) system and a diesel particulate filter (DPF), aligning with Euro 4 and later Euro 5 standards.
A documented service concern involves the premature failure of the high-pressure fuel pump, which can lead to a complete loss of power or an inability to start. This is referenced in Renault Service Note MEC‑112. The pump's failure is often linked to fuel contamination or the use of incorrect oil specifications affecting the pump's lubrication via the engine oil circuit.
Production years 2006–2009 meet Euro 4 standards; 2010–2014 models meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Renault 847 725 is a 1,995 cc inline‑four turbo‑diesel engineered for light commercial vehicles (2006-2014). It combines a high-pressure common-rail fuel system with a variable geometry turbocharger to deliver strong, linear power and improved fuel economy. Designed to meet Euro 4 and Euro 5 standards, it represents a significant technological advancement over the previous 1.9L generation.

The VGT turbo provides strong, lag-free torque from low RPMs, ideal for urban van duties. The common-rail system demands ultra-low-sulfur diesel (ULSD) to prevent injector and high-pressure pump wear. The chain-driven timing system is designed for longevity but requires correct oil specification (ACEA C3) for lubrication. The high-pressure fuel pump is integrated into the engine's oil circuit; using incorrect oil or contaminated fuel is a primary cause of premature failure, as noted in Service Note MEC‑112.
Oil Specs: Requires ACEA C3 specification oil (Renault Technical Manual RTM-847). A 5W-30 fully synthetic oil is recommended for optimal protection of the timing chain and fuel pump.
Emissions: Euro 4 certification applies to 2006–2009 models; Euro 5 applies to 2010–2014 models (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all applications (Renault Group PT‑2008).

The Renault 847 725 was used across Renault's Trafic and Master platforms with longitudinal mounting. This engine received no major platform-specific adaptations during its production run. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, typically near the gearbox flange or on the front timing cover (Renault RTM-847). The code "847 725" is clearly marked. Visually, it can be identified by its common-rail fuel injectors and the variable geometry turbocharger. Differentiate from the earlier 841 725 by its larger 2.0L displacement and Delphi fuel system, as opposed to the 1.9L and Siemens system. Service parts for the 847 725 are specific and not interchangeable with the 841 725.
The 847 725's primary reliability risk is failure of the high-pressure fuel pump, with elevated incidence in vehicles using poor-quality fuel or incorrect engine oil. Renault internal service data indicates this is the most common major component failure, while its failure often strands the vehicle. Strict adherence to fuel and oil specifications is critical for longevity.
