The Renault G9T 712 is a 2,299 cc, inline‑four turbo‑diesel engine produced between 2018 and 2021. It features a high-pressure common-rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In its primary application, it delivers 110 kW (150 PS) and 340 Nm of torque, offering a balance of efficiency and load-carrying capability for commercial use.
Fitted predominantly to the Renault Master van and its badge-engineered counterparts like the Nissan NV400 and Opel/Vauxhall Movano B, the G9T 712 was engineered for operational economy and emissions compliance. Emissions standards for Euro 6d-TEMP were met through a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue, positioning it for urban delivery and regional haulage.
A documented service concern involves the Exhaust Gas Recirculation (EGR) valve, prone to carbon buildup leading to erratic operation and fault codes. This issue, referenced in Renault's technical service bulletins, can cause rough idling and increased emissions. Production ceased in 2021 as Renault transitioned its commercial vehicle lineup to newer engine families.
All production years 2018–2021 meet Euro 6d-TEMP standards for light commercial vehicles (VCA UK Type Approval #VCA/LCV/5679).
The Renault G9T 712 is a 2,299 cc inline‑four turbo‑diesel engineered for light commercial vehicles (2018-2021). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver efficient torque for urban and highway operation. Designed to meet Euro 6d-TEMP standards, it prioritizes emissions compliance and fuel economy for fleet operators.

The moderate power output makes the G9T 712 ideal for urban delivery cycles but necessitates strict adherence to 20,000 km or 12-month service intervals to maintain the DPF and SCR systems. Renault RN0720 (5W-30) oil is mandatory to protect the high-pressure fuel pump. The EGR valve is a known failure point; any sign of rough idle or emissions warning lights warrants cleaning or replacement per Renault technical guidance. Using low-quality AdBlue can damage the SCR catalyst. The timing chain is generally robust.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault Owner's Manual). Compatible with ACEA C4.
Emissions: Euro 6d-TEMP certification applies to all 2018-2021 models for LCV classification (VCA Type Approval #VCA/LCV/5679).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across approved applications (Renault TIS Doc. G9T-003).

The Renault G9T 712 was used primarily in Renault's Master III platform with longitudinal mounting. This engine received platform-specific adaptations-optimized cooling for the van's front end-and no significant facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface on the front left side of the cylinder block, below the exhaust manifold (Renault TIS G9T-004). The 8th digit of the VIN for Renault Master applications is typically 'G' for this engine family. Visually, it can be identified by its large top-mounted intercooler and the AdBlue tank located near the fuel filler. Differentiation from the higher-powered G9T 606 is by power output and ECU mapping; physical components are largely identical. Service parts are generally interchangeable across the G9T family for the same model year.
The G9T 712's primary reliability risk is EGR valve carbon buildup, with elevated incidence in stop-start urban driving. Renault workshop data indicates this as a frequent cause of emissions-related faults, while AdBlue system issues are common in vehicles using non-compliant fluid. Neglecting DPF regeneration cycles and using incorrect oil make EGR and emissions system failures more likely.
