The Renault M9T 680 is a 2,298 cc, inline‑four turbo‑diesel engine produced between 2011 and 2018. It features a twin‑scroll variable geometry turbocharger (VGT), Bosch common‑rail direct injection (up to 1,800 bar), and a dual overhead camshaft (DOHC) 16‑valve layout. Output is rated at 110 kW (150 PS) with peak torque of 340 Nm, delivering strong low‑rpm pull ideal for commercial and passenger applications.
Fitted to models including the Trafic III, Master III, and Nissan NV300, the M9T 680 was engineered for durability, fuel efficiency, and emissions compliance in light‑commercial vehicles. Emissions control was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF), enabling full Euro 5 compliance across all production years.
One documented concern is high‑pressure fuel pump wear under marginal lubrication conditions, highlighted in Renault Service Bulletin 6014A. This issue stems from the use of ultra‑low‑sulfur diesel with extended oil change intervals. In 2013, Renault updated the pump design and reinforced oil change recommendations to mitigate internal wear.
All production years (2011–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Renault M9T 680 is a 2,298 cc inline‑four turbo‑diesel engineered for light-commercial vans and MPVs (2011–2018). It combines Bosch common‑rail injection with a twin‑scroll variable‑geometry turbocharger to deliver strong low‑end torque and long-haul reliability. Designed to meet Euro 5 emissions standards, it balances load-carrying capability with fuel economy.

The twin-scroll VGT provides strong low-RPM torque ideal for stop-start delivery cycles but demands strict adherence to 15,000 km oil change intervals using Renault RN0720 (5W-30) to protect the Bosch CP4.2 high-pressure fuel pump. Extended intervals or non-compliant oil accelerate pump wear due to marginal lubricity of ultra-low-sulfur diesel. EGR and DPF systems require periodic regeneration and cleaning to avoid limp-mode; urban driving below 2,000 rpm may increase soot accumulation. No major timing chain issues are documented, but coolant leaks from the EGR cooler housing have been noted in pre-2014 builds (Renault SIB 6014A).
Oil Specs: Requires Renault RN0720 (ACEA C3, 5W-30) specification (Renault SIB 6014A).
Emissions: Euro 5 certification applies to all M9T 680 models (2011–2018) (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under UN ECE R85 standards. 110 kW output requires EN 590 diesel (Renault TIS Doc. M9T‑A201).

The Renault M9T 680 was used across Renault's Trafic III and Master III platforms with transverse mounting and shared with Nissan and Opel/Vauxhall for light-commercial applications in European markets. This engine received platform-specific adaptations—reinforced sump in the Master and revised EGR routing in the Trafic—and from 2015 the facelifted Trafic III adopted updated fuel pump hardware, creating interchange limits. Partnerships allowed Nissan's NV300 and Opel Vivaro to use identical M9T 680 units. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the left-side engine block near the cylinder head (Renault TIS M9T‑A101). The 7th VIN digit indicates engine family ('9' for M9T series). Pre-2015 models use a silver Bosch CP4.2 pump with single electrical connector; post-2015 units feature a black pump with dual connectors. Critical differentiation from M9T 700: M9T 680 has lower power output (110 kW vs 120 kW) and identical displacement. Service parts require production date verification—fuel pump kits for engines before 06/2013 are incompatible with later units due to internal redesign (Renault SIB 6014A).
The M9T 680's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using non-compliant oil or extended service intervals. Renault internal data from 2014 indicated a significant share of pre-2013 pumps failing before 100,000 km, while UK DVSA MOT records show DPF-related emissions faults rising in urban-driven examples. Short-trip driving and poor-quality diesel accelerate pump and EGR degradation, making oil specification and fuel quality critical.
