The Renault G9U 632 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 double overhead camshafts (DOHC). In standard applications, it delivers 120 kW (163 PS) and 380 Nm of torque, with higher-output variants reaching 140 kW (190 PS).
Fitted primarily to the Renault Master van and its badge-engineered counterparts like the Nissan NV400 and Opel/Vauxhall Movano B, the G9U 632 was engineered for commercial durability, offering strong low-end pulling power and fuel efficiency under load. Emissions compliance for its production run was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 6 standards.
A documented concern for early production units is premature failure of the high-pressure fuel pump, potentially leading to sudden engine cut-out. This issue, referenced in Renault Service Bulletin RSB 22-015, is often linked to fuel contamination or inadequate filtration. Renault implemented revised pump internals and updated fuel filter service intervals from 2017 onwards.
All production years (2015–2021) meet Euro 6 standards for light commercial vehicles (VCA UK Type Approval #VCA/LCV/5678).
The Renault G9U 632 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 highway cruising. Designed to meet Euro 6 standards, it prioritizes durability and operational economy for fleet use.

The robust torque output makes the G9U 632 ideal for heavy payloads but demands strict adherence to 20,000 km or annual oil and filter changes using RN0720 specification oil to protect the turbo and fuel system. Ultra-low-sulfur diesel (ULSD) meeting EN 590 is mandatory to prevent CP4.2 pump failure. Vehicles used for frequent short trips require more frequent DPF regeneration cycles. Early models (pre-2017) should have the fuel pump inspected per RSB 22-015 if experiencing hesitation or stalling. EGR valve cleaning is recommended every 80,000 km to maintain performance.
Oil Specs: Requires Renault RN0720 (ACEA C4) specification (Renault Owner's Manual). Compatible with BMW LL-04.
Emissions: Euro 6 certification applies to all model years (2015-2021) for LCVs (VCA Type Approval #VCA/LCV/5678).
Power Ratings: Measured under ISO 1585 standards. Higher 140 kW output requires premium diesel (Renault TIS Doc. R-MECH-2210).

The Renault G9U 632 was used across Renault's Master platform with longitudinal mounting. This engine received platform-specific adaptations-unique engine mounts and ancillary layouts for the Master-and was also supplied to Nissan and Opel/Vauxhall for their respective large van models, creating a shared parts ecosystem. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface on the front left side of the cylinder block, below the exhaust manifold (Renault TIS R-MECH-2200). The 8th digit of the VIN is 'G' for this engine family. Visually, it can be identified by its large, top-mounted intercooler and the Bosch EDC17C84 ECU located on the passenger side of the engine bay. Critical differentiation from the smaller 2.0 dCi: The G9U 632 has a visibly larger displacement and a distinct intake manifold design. Service parts, particularly for the fuel system, are often shared across Renault, Nissan, and Opel/Vauxhall variants but require verification of the specific engine code.
The G9U 632's primary reliability risk is high-pressure fuel pump (HPFP) failure in early builds, with elevated incidence in vehicles subjected to poor fuel quality or infrequent filter changes. Renault internal service data indicated a higher-than-average failure rate for pumps manufactured before Q3 2016, while fleet operator reports frequently cite EGR system clogging as a secondary concern under urban duty cycles. Consistent use of premium diesel and timely maintenance are critical for long-term reliability.
