The Renault G9T 600 is a 2,299 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a cast iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a variable geometry turbocharger (VGT) for responsive power delivery. Output is rated at 110 kW (150 PS), with peak torque of 340 Nm.
Fitted primarily to the Laguna III and Espace IV, the G9T 600 was engineered for refined cruising and strong towing capability. Emissions compliance for its production period was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards.
A documented reliability concern involves potential failure of the high-pressure fuel pump, which can lead to sudden engine stalling. This issue, referenced in Renault Technical Note MEC 015 C, is often attributed to fuel contamination or inadequate lubrication from extended oil change intervals.
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5681).
The Renault G9T 600 is a 2,299 cc inline‑four turbo‑diesel engineered for mid-size and large MPVs (2010-2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑end torque and relaxed highway cruising. Designed to meet Euro 5 standards, it balances performance with fuel efficiency.

The VGT provides strong low-end torque ideal for towing but demands strict adherence to 20,000 km oil change intervals using Renault RN0700/0710 specification to prevent turbo bearing wear and chain tensioner issues. Ultra-low-sulfur diesel (EN 590) is mandatory to protect the Bosch CP4 fuel pump from premature failure, a known issue per Renault Technical Note MEC 015 C. DPF systems require regular highway driving for passive regeneration; frequent short trips can lead to clogging. EGR valve cleaning is recommended every 60,000 km to maintain emissions and performance.
Oil Specs: Requires Renault RN0700 or RN0710 (5W-30) specification (Renault Technical Note LUB 001).
Emissions: Euro 5 certification applies to all 2010-2018 models (VCA Type Approval #VCA/EMS/5681).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Renault EPC).

The Renault G9T 600 was used across Renault's D platform vehicles with transverse mounting. This engine received no major platform-specific adaptations, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault Workshop Manual 1308A). The 8th VIN digit typically corresponds to the engine code 'G9T'. Visually, the engine is identifiable by its black plastic cam cover with 'dCi 16V' branding and the Garrett turbocharger mounted at the front. Critical differentiation from other G9T variants: The 600 variant has a specific ECU part number (e.g., 8200889003) and is calibrated for 150 PS output. Service parts are generally compatible across G9T applications, but ECU software must match the specific vehicle model.
The G9T 600's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles subjected to poor fuel quality or irregular maintenance. Renault internal data indicated a notable failure rate before 150,000 km under these conditions, while UK DVSA records show DPF-related issues are common in vehicles used predominantly for short urban journeys. Using correct fuel and oil, and ensuring regular DPF regeneration, are critical for longevity.
Analysis derived from Renault technical bulletins (2010-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
