The Renault G9T 754 is a 1,749 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 dual overhead camshafts (DOHC). In its primary application, it delivers 96 kW (130 PS) and 340 Nm of torque, offering a balance of efficiency and responsive performance for mid — size vehicles.
Fitted predominantly to the Renault Kadjar and Nissan Qashqai (J11 facelift), the G…
Production years 2018–2020 meet Euro 6d-TEMP standards; 2021–2023 models comply with Euro 6d standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault G9T 754 is a 1,749 cc inline‑four turbo‑diesel engineered for compact SUVs (2018-2023). It combines a high-pressure common-rail injection system with a single variable‑geometry turbocharger to deliver strong low‑end torque and efficient highway cruising. Designed to meet Euro 6d-TEMP and Euro 6d standards, it balances performance with stringent emissions control.

The Renault G9T 754 was used across Renault's CMF-CD platform with transverse mounting. This engine received platform-specific adaptations-shared ECU calibration with the Nissan MR20DDT petrol engine for hybrid variants-and from 2021, software updates to meet Euro 6d standards, creating minor ECU calibration differences. All adaptations are documented in OEM technical bulletins.
The G9T 754's primary reliability consideration is EGR system fouling, with elevated incidence in vehicles used for short urban journeys. Renault technical bulletins indicate this is the most frequent cause of performance-related service visits, while adherence to the correct oil specification is paramount for long-term DPF and turbo health. Neglecting maintenance intervals significantly increases the risk of costly emissions system repairs.
Analysis derived from Renault technical bulletins (2018-2023) and UK DVSA failure statistics (2020-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The G9T 754 is generally robust mechanically, with a durable timing chain. Its long-term reliability heavily depends on strict adherence to maintenance, particularly using the correct RN17 5W-30 oil and addressing EGR/DPF issues promptly. Vehicles used for longer journeys tend to fare better than those on short urban trips.
The most frequent issues are EGR valve/cooler clogging and associated DPF regeneration problems. Other concerns include failures of the high-pressure fuel pump and turbocharger actuator solenoids. These are well-documented in Renault service information bulletins.
The G9T 754 was primarily used in the Renault Kadjar (dCi 130 / Blue dCi 130) from 2018 to 2023. It was also used in the Nissan Qashqai (J11 facelift, dCi 130 variant) from 2019 to 2021, as part of the Renault-Nissan alliance.
Yes, ECU remapping is common and can yield power increases to around 160-170 PS and 380-400 Nm. The engine's internals are generally capable of handling this safely. However, increased power puts more strain on the turbo, clutch, and emissions systems, potentially reducing their lifespan.
Official combined figures for the Kadjar dCi 130 are around 5.3 L/100km (53 mpg UK). Real-world consumption typically ranges from 6.0 L/100km (47 mpg UK) in mixed driving to 7.5 L/100km (38 mpg UK) in heavy city traffic. Highway driving can achieve under 5.0 L/100km (56 mpg UK).
Yes. The G9T 754 is an interference engine. 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 RN17 5W-30 specification oil. High-quality ACEA C2 or C3 5W-30 oils are also suitable alternatives. Using the correct low-ash oil is critical for protecting the DPF and ensuring proper engine lubrication.
