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.

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 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.
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 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The G9T 712 is generally reliable for its intended commercial use, provided maintenance is meticulous. The most common failure point is the EGR valve due to carbon buildup, particularly in urban driving. Adhering to service schedules and using the correct fluids significantly improves long-term reliability and prevents costly emissions system failures.
The most frequent issues are EGR valve sticking due to carbon deposits, AdBlue system faults from poor-quality fluid, DPF clogging from short journeys, and occasional turbo actuator failures. These are well-documented in Renault service information and are common across many modern diesel engines with similar emissions systems.
The G9T 712 was used almost exclusively in the Renault Master III (Phase 2) van from 2018 to 2021, badged as the dCi 150. It was also fitted to its platform siblings: the Nissan NV400 and the Opel/Vauxhall Movano B, all sharing the same 150 PS output specification for this variant.
Aftermarket ECU tuning is common on the G9T-712 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is good for a large van. In a Renault Master with a gross weight of 3.5 tonnes, expect 34-40 mpg (UK) or 7.1-8.3 L/100km on a mixed cycle. Highway driving can yield up to 42 mpg (UK), while urban, stop-start driving with a heavy load will be lower, around 28-32 mpg (UK).
Yes. Like virtually all modern engines, the G9T 712 is an interference design. If the timing chain were to fail (though rare), the pistons would collide with the open valves, causing catastrophic internal engine damage requiring a full rebuild or replacement.
Renault mandates the use of RN0720 specification oil, typically a 5W-30 synthetic. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is critical for protecting the DPF and SCR systems from clogging and ensuring the longevity of the turbocharger and fuel system components.
