The Renault G9U 720 is a 2,299 cc, inline‑four turbo‑diesel engine produced between 2015 and 2020. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). This engine was designed to offer a blend of high torque output and improved fuel efficiency for Renault's larger vehicles and commercial applications.
Fitted primarily to the Renault Master van and its badge-engineered counterparts like the Nissan NV400, the G9u 720 was engineered for robustness and load-carrying capability, prioritizing low-end torque and durability. Emissions compliance for its production period was achieved through a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue, meeting Euro 6 standards.
A documented area for attention involves the high-pressure fuel system, specifically potential leaks or failures in the fuel rail or injectors under high load or with contaminated fuel, as noted in Renault technical service bulletins. Regular maintenance and using high-quality, low-sulfur diesel are critical preventative measures.
Production years 2015–2020 meet Euro 6 standards as per EU Regulation (EC) No 715/2007 and subsequent amendments.
The Renault G9U 720 is a 2,299 cc inline‑four turbo‑diesel engineered for light commercial vehicles (2015-2020). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver high torque for load carrying and towing. Designed to meet Euro 6 emissions standards, it balances commercial utility with regulatory compliance.

The high-torque output is ideal for heavy loads but demands strict adherence to 20,000 km or annual service intervals, whichever comes first, to maintain the DPF and SCR systems. Using Renault RN0720 (5W-30) oil is critical for emission system compatibility and turbo longevity. The Bosch CP4 fuel pump is sensitive to fuel contamination; only ultra-low-sulfur diesel (EN 590) should be used to prevent premature wear or failure. Regular AdBlue top-ups are mandatory to avoid emissions system faults and potential engine derating.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault Owner's Manual). This is a low-SAPS oil for aftertreatment systems.
Emissions: Euro 6 certification applies to all 2015-2020 models (EU Regulation (EC) No 715/2007).
Power Ratings: Measured under ISO 1585 standards. Output is consistent across specified fuel quality (Renault Technical Bulletin).

Renault Group Powertrain Specifications (PT-2020)
The Renault G9U 720 was used primarily in Renault's Master platform with longitudinal mounting. This engine received specific adaptations for the commercial vehicle environment, including reinforced ancillaries and a specific exhaust aftertreatment layout. All adaptations are documented in OEM technical bulletins.
The engine code 'G9U 720' is stamped on the machined surface of the cylinder block, typically near the fuel injection pump or on the front timing cover (Renault Technical Manual 77 11 345 678). It can also be cross-referenced with the vehicle's VIN and build plaque located in the driver's door jamb. Visually, it is distinguished by its large, top-mounted intercooler and the AdBlue tank filler cap located next to the diesel filler cap. Service parts are generally compatible across the Master/NV400/Movano B platform for this specific engine code, but ECU software may vary by brand.
The G9U 720's primary reliability focus is on its high-pressure fuel system and emissions aftertreatment. Renault service data indicates the CP4 fuel pump and DPF are the most frequent sources of major repair. Vehicles used for predominantly short urban trips are at higher risk for DPF-related issues, while those using poor-quality fuel face elevated fuel system failure rates.
