The Renault G9T 722 is a 2,299 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. It features a high — pressure common — rail fuel system, a variable geometry turbocharger (VGT), and double overhead camshafts (DOHC). This iteration delivers 125 kW (170 PS) and 400 Nm of torque, engineered for consistent performance under load in commercial applications.

Production years 2018–2023 meet Euro 6d-TEMP/Euro 6d standards across all applicable markets .
The Renault G9T 722 is a 2,299 cc inline‑four turbo‑diesel engineered for light commercial vehicles (2018-2023). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver high torque for load-carrying and towing. Designed to meet Euro 6d standards, it balances commercial durability with regulatory compliance.

The Renault G9T 722 was used across Renault's light commercial platforms with longitudinal mounting. This engine features the updated EGR cooler and emissions calibration from launch and shares its core architecture with the Nissan YS23DDTT engine used in the NV300/NV400. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The G9T 722 is generally reliable for commercial use, benefiting from the revised EGR cooler that addressed the main weakness of its predecessor. Its longevity is heavily dependent on maintenance, particularly regarding the DPF and using the correct RN0720 oil. With proper care, these engines can reliably exceed 250,000 km in fleet service.
The most frequent issues are DPF clogging (especially with urban driving), turbo actuator failures, EGR valve carbon buildup, and injector seal leaks. These are well-documented in Renault and Nissan service bulletins for the Master IV, Trafic III, NV300, and NV400 from the 2018-2023 model years.
The G9T 722 was used in the Renault Master IV (2018-2023) and Trafic III (2018-2023), badged specifically as the dCi 170. It was also used by Nissan in the NV300 and NV400 (2018-2023) as the 2.3 dCi 170, sharing the same updated engine architecture and emissions calibration.
Aftermarket ECU tuning is common on the G9T-722 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 varies by vehicle and load. In a Renault Trafic, expect 7.8-9.2 L/100km (30-36 mpg UK) combined. In a heavier Master van, figures are typically 9.5-11.5 L/100km (25-30 mpg UK). Real-world consumption is highly dependent on payload, route type, and adherence to DPF regeneration cycles.
Yes. The G9T 722 is an interference engine. If the timing chain fails or skips, the pistons will collide with the open valves, causing catastrophic internal damage. While the chain is designed for the engine's lifespan, any unusual rattling noise should be investigated immediately by a professional.
Renault mandates the use of RN0720 specification oil, typically a 5W-30 synthetic. This is non-negotiable, as the correct oil is critical for protecting the high-pressure fuel pump, turbocharger, and ensuring the DPF functions correctly by minimizing ash content. Never use an oil that does not meet the RN0720 standard.
