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 G9T 754 was engineered for refined daily driving with an emphasis on low-end torque and fuel economy. Emissions compliance for European markets was achieved through a combination of exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting stringent Euro 6d-TEMP and Euro 6d standards.
One documented area for attention is the potential for the EGR valve and cooler to become clogged with soot over time, particularly in vehicles subjected to predominantly short journeys. This issue, referenced in Renault technical service bulletins, can lead to reduced performance and increased DPF regeneration cycles. Regular maintenance and the use of correct engine oil are critical preventative measures.
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 engine provides ample torque for effortless acceleration but requires adherence to 20,000 km or 12-month oil change intervals using RN17 5W-30 specification to protect the turbo and DPF systems. Ultra-low-sulfur diesel (ULSD) is mandatory to prevent damage to the high-pressure fuel pump and injectors. Vehicles used primarily for short trips are more susceptible to EGR and DPF issues; periodic longer highway drives are recommended to facilitate passive regeneration. The timing chain is generally robust but relies on clean oil for longevity.
Oil Specs: Requires Renault RN17 5W-30 specification (Renault Owner's Manual). ACEA C2/C3 oils are acceptable alternatives.
Emissions: Euro 6d-TEMP certification applies to 2018-2020 models; Euro 6d for 2021-2023 (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model years (Renault TIS Doc. R-MECH-8890).

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 engine code 'G9T 754' is stamped on a metal plate riveted to the cylinder head, near the front of the engine (Renault TIS R-ID-001). The 8th digit of the VIN for Renault Kadjar is 'G' for this engine family. Visually, it can be identified by its black plastic engine cover with 'dCi' branding and the location of the EGR cooler on the left side of the engine bay. Differentiation from the lower-powered G9T 752 is primarily via ECU software and badging; physical hardware is largely identical. Always verify the engine code plate for definitive identification before ordering parts.
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.
