The Renault G9T 606 is a 2,299 cc, inline‑four turbo‑diesel engine produced between 2015 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 140 kW (190 PS) and 380 Nm of torque, providing strong pulling power for larger vehicles.
Fitted predominantly to the Renault Master van and its badge — engineered counterparts like the Nissan NV400 and Op…
All production years 2015–2021 meet Euro 6b/6c standards for light commercial vehicles .
The Renault G9T 606 is a 2,299 cc inline‑four turbo‑diesel engineered for light commercial vehicles (2015-2021). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver high torque for load-carrying and efficient long-distance cruising. Designed to meet Euro 6 standards, it balances commercial utility with regulatory compliance.

The Renault G9T 606 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 606's primary reliability risk is EGR cooler failure, with elevated incidence in high-mileage or poorly maintained vehicles. Renault workshop data indicates this as a frequent cause of major engine repairs, while AdBlue system faults 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 606 is generally robust for commercial use, but its long-term reliability hinges on meticulous maintenance. The EGR cooler is a known weak point, and neglecting the AdBlue or DPF systems leads to expensive failures. With strict adherence to service schedules and correct fluids, it can achieve high mileage reliably.
The most frequent issues are EGR cooler leaks causing coolant loss, AdBlue system faults from poor-quality fluid, DPF clogging due to short journeys, and turbo actuator failures. These are well-documented in Renault service information and technical forums for commercial vehicles.
The G9T 606 was used almost exclusively in the Renault Master III (Phase 2) van from 2015 to 2021, badged as the dCi 170. It was also fitted to its platform siblings: the Nissan NV400 and the Opel/Vauxhall Movano B, all sharing the same 190 PS output.
Aftermarket ECU tuning is common on the G9T-606 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 respectable for a large van. In a Renault Master with a gross weight of 3.5 tonnes, expect 32-38 mpg (UK) or 7.4-8.8 L/100km on a mixed cycle. Highway driving can yield up to 40 mpg (UK), while urban, stop-start driving with a heavy load will be significantly lower.
Yes. Like virtually all modern engines, the G9T 606 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.
