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.

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 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.
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.
Analysis derived from Renault technical bulletins (2006-2014) and UK DVSA failure statistics (2010-2020). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 847 725 is generally robust but its long-term reliability is heavily dependent on the high-pressure fuel pump. With meticulous use of high-quality fuel and strict adherence to the ACEA C3 oil specification, these engines can achieve high mileage. Neglecting these factors is the primary cause of expensive pump failure.
The most common and critical problem is high-pressure fuel pump failure. Other frequent issues include DPF regeneration problems due to short trips, EGR system clogging leading to power loss, and turbocharger actuator failures affecting boost. These are well-documented in Renault service notes.
The 847 725 engine was used in the Renault Trafic II (Phase 2) from 2006 to 2014 and the Master II from 2007 to 2010. It was also used in the nearly identical Opel/Vauxhall Vivaro C and Nissan Primastar models during the same period, all badged as 2.0 dCi or CDTi with 130 PS.
Yes, the 847 725 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 150-160 PS and torque to 340-360 Nm. However, increased power will accelerate wear on the clutch and drivetrain components, and puts additional stress on the high-pressure fuel pump, so reliability may be compromised without supporting modifications.
Fuel economy is good for a van of its size. Expect approximately 7.0-8.0 L/100km (35-40 mpg UK) in combined driving for a Trafic. Real-world figures are heavily influenced by load, driving style, and the condition of the DPF and EGR systems. Regular highway driving helps maintain DPF health and improves economy.
Yes. The 847 725 is an interference engine. If the timing chain breaks or slips, the pistons will collide with the open valves, causing severe internal damage that typically requires a cylinder head rebuild or engine replacement. While the chain is designed to last, any unusual noise should be investigated immediately.
Renault specifies an oil meeting the ACEA C3 standard. A good quality 5W-30 fully synthetic oil is mandatory, as it is required to lubricate the high-pressure fuel pump via the engine's oil circuit. Using the correct specification is vital for preventing premature pump failure and ensuring engine longevity.
