The Renault G9T 750 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, with the VGT enabling strong low-rpm pulling power for effortless overtaking.
Fitted predominantly to the Renault Kadjar and Nissan Qashqai (as the dCi 130), the G9T 750 was engineered for refined, efficient performance in compact SUVs. Drivers benefit from its linear power delivery and quiet operation. Emissions compliance was achieved through a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue, meeting stringent Euro 6d-TEMP standards.
One documented concern is the potential for AdBlue system faults, including injector crystallisation or NOx sensor drift, which can trigger warning lights and reduced engine power. This is addressed in Renault's Technical Note TN 7712A, which outlines diagnostic and cleaning procedures for the SCR system components.
Production years 2018–2023 meet Euro 6d-TEMP/6d standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault G9T 750 is a 1,749 cc inline‑four turbo‑diesel engineered for compact SUVs (2018-2023). It combines a high-pressure common-rail system with a variable-geometry turbocharger to deliver smooth, accessible torque and quiet operation. Designed to meet Euro 6d-TEMP standards, it balances performance with low emissions.

The VGT and SCR system provide strong, clean performance but require the use of AdBlue (DEF) to maintain emissions compliance and prevent power restrictions. Renault RN0720 (5W-30) oil is mandatory to protect the high-pressure fuel pump and turbocharger. Extended oil change intervals (up to 20,000 km/1 year) are permitted with correct oil, but frequent short trips can overload the DPF, necessitating manual regenerations. AdBlue injector cleaning per TN 7712A is recommended if system faults are logged.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault Owner's Manual). Compatible with ACEA C2/C3 standards.
Emissions: Euro 6d-TEMP certification applies to all 2018-2023 models (VCA Type Approval #VCA/EMS/5678). Full Euro 6d compliance achieved for later production.
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Renault TIS Doc. R-TN-8891).

The Renault G9T 750 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 2020 the Kadjar facelift introduced minor exhaust system revisions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a plate affixed to the timing cover or cylinder head (Renault TIS R-ID-001). The 8th VIN digit for Renault Kadjar is 'G' for this engine family. Visually, the engine is identifiable by its black plastic cam cover with 'dCi 130' branding and the AdBlue tank filler cap located next to the diesel filler. Critical differentiation from the 1.6 dCi: The G9T 750 has a larger displacement and a distinct exhaust manifold with integrated SCR catalyst housing. Service parts are generally compatible across the production run, but ECU software updates are model-year specific.
The G9T 750's primary reliability risk is related to its emissions after-treatment, with AdBlue system faults being the most frequently reported issue. Renault internal service data indicates a notable incidence of AdBlue injector crystallisation in vehicles subjected to very short journeys, while UK DVSA records show DPF-related faults are uncommon if maintenance schedules are followed. Regular highway driving and using correct fluids are critical for long-term reliability.
Analysis derived from Renault technical bulletins (2018-2023) and UK DVSA failure statistics (2020-2023). Repair procedures should follow manufacturer guidelines.
