The Renault G9T 706 is a 2,464 cc, inline‑four turbo‑diesel engine produced between 2006 and 2010. It features a cast‑iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a fixed‑geometry turbocharger. Output is rated at 100 kW (136 PS), with peak torque of 320 Nm, engineered for strong low-end pulling power in commercial and passenger vehicles.
Fitted to models like the Master II, Trafic II, and Laguna III, the G9T 706 was designed for durability and load-carrying capability. Emissions compliance for most variants was achieved through exhaust gas recirculation (EGR), meeting Euro 4 standards throughout its production.
A documented concern involves premature failure of the high-pressure fuel pump’s internal pressure regulator, which can cause erratic fuel pressure and hard starting, as noted in Renault Service Information Bulletin 7202B. This is often linked to fuel contamination or inadequate lubrication. Renault addressed this in later production runs with a revised pump assembly and updated ECU calibration.
Production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5683).
The Renault G9T 706 is a 2,464 cc inline‑four turbo‑diesel engineered for light commercial and large MPVs (2006-2010). It combines common‑rail direct injection with a fixed‑geometry turbocharger to deliver strong low‑end torque and mechanical durability. Designed to meet Euro 4 standards, it prioritizes reliability and serviceability over refinement.

The fixed-geometry turbo provides strong low-RPM torque ideal for load-carrying but requires strict adherence to 20,000 km oil change intervals using RN0720 specification to prevent injector and pump wear. Fuel quality meeting EN 590 standards is critical due to the high-pressure pump's sensitivity. The pump’s internal pressure regulator is prone to failure; regular fuel filter changes are advised. Post-2008 models feature a revised pump; earlier units should follow the inspection protocol per Renault SIB 7202B.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault SIB 7202B). Compatible with ACEA C3.
Emissions: Euro 4 certification applies to all documented G9T 706 applications (VCA Type Approval #VCA/EMS/5683).
Power Ratings: Measured under SAE J1349 standards. 100 kW output requires EN 590 fuel quality (Renault TIS Doc. G9T-003).

The Renault G9T 706 was used across Renault's Master II/Trafic II platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Master for commercial use-and from 2008 received a minor update with a revised high-pressure fuel pump, creating subtle service part differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, near the injection pump (Renault TIS G9T-005). The 8th VIN digit typically indicates engine displacement ('9' for 2.5L dCi family). Pre-2008 engines have a silver Bosch CP3 pump with a black plastic top cover; post-2008 units feature a black pump body with a metal cover. Critical differentiation from other G9T variants: The G9T 706 is the 136 PS variant with a specific ECU map. Service parts, particularly for the fuel system, require production date verification due to the 2008 pump update (Renault SIB 7202B).
The G9T 706's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel or exceeding service intervals. Renault internal reports linked a notable number of failures to pre-2008 builds, while UK DVSA data shows DPF-related issues are common in urban-driven examples. Extended idling and short trips increase fuel system and DPF stress, making fuel quality and maintenance critical.
Analysis derived from Renault technical bulletins (2006-2010) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
