The Renault Master III Phase III, launched in 2019, represents a significant update to Renault’s large van lineup. Specifically, the 2.3 dCi 135 horsepower variant in the L3H2 configuration – a long-wheelbase, high-roof model – became a popular choice for commercial operators and those needing substantial cargo capacity. This version aimed to balance fuel efficiency, practicality, and a reasonable purchase price within the broader Master range. The Phase III updates brought refinements to the interior, exterior styling, and crucially, the engine and emissions systems to meet increasingly stringent Euro 6d-Temp standards. It primarily served the European market, where large vans are essential for delivery services, tradespeople, and conversions to camper vans.

INTRODUCTION
The Renault Master III Phase III 2.3 dCi 135 L3H2 is a large panel van designed for commercial use, offering a substantial cargo volume and payload capacity. Introduced in 2019 as part of the Master III’s mid-life refresh, this variant caters to businesses and individuals requiring a versatile and relatively economical workhorse. The L3H2 designation signifies a long wheelbase and high roof, maximizing interior space. Positioned as a mid-range offering within the Master lineup, it slots between the lower-powered, more basic models and the higher-output, more luxurious trims. It builds upon the foundation of the X62 platform, shared with other Renault and Nissan commercial vehicles.
Powertrain & Engine Architecture
At the heart of this Master variant lies the Renault M9T 2.3-liter four-cylinder diesel engine. This engine utilizes a common-rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The 135 horsepower output is achieved through the use of a twin-turbocharger setup, combining a small turbo for quick response at low engine speeds and a larger turbo for sustained power at higher RPMs. An intercooler further enhances performance by cooling the intake air. The engine meets Euro 6d-Temp emissions standards through the use of a diesel particulate filter (DPF) and selective catalytic reduction (SCR) system, requiring the use of AdBlue. The engine is paired with a six-speed manual transmission, chosen for its durability and fuel efficiency. While an automated manual transmission (AMT) was available on some Master models, the 135 hp version was primarily offered with the manual.
Driving Characteristics
The 135 horsepower output, coupled with 360 Nm (265 lb-ft) of torque, provides adequate performance for typical commercial van duties. Acceleration is not brisk, but the engine delivers sufficient power for highway cruising and carrying heavy loads. The six-speed manual transmission allows for efficient gear selection, keeping the engine within its optimal torque band. Compared to the higher-output 170 hp version, the 135 hp model feels noticeably less powerful, particularly when fully loaded or climbing hills. However, this trade-off results in improved fuel economy. The gear ratios are tuned for practicality rather than performance, prioritizing load-carrying ability and fuel efficiency over spirited driving. The front-wheel-drive configuration provides reasonable handling, but the van’s high center of gravity and substantial weight limit cornering agility.
Equipment & Trim Levels
The Master III Phase III 2.3 dCi 135 L3H2 typically came equipped with a functional, rather than luxurious, interior. Standard features included a driver’s airbag, ABS brakes, electronic stability control, and a basic audio system with USB connectivity. The cabin typically featured durable plastic trim and hard-wearing cloth upholstery. Air conditioning and a rear parking sensor were often standard, but could vary depending on the specific market. Optional extras included a navigation system, a rearview camera, cruise control, and upgraded seating. The focus was on providing a practical and durable work environment, rather than premium comfort.
Chassis & Braking
The Master III utilizes a robust ladder-frame chassis, providing a solid foundation for heavy loads. The front suspension consists of independent McPherson struts with a coil spring and anti-roll bar, while the rear suspension employs leaf springs. This configuration prioritizes load-carrying capacity and durability over ride comfort. The braking system features ventilated discs on the front wheels and solid discs on the rear. The size of the front discs is 302mm, while the rear discs measure 305mm. The steering is hydraulic power-assisted, providing reasonable maneuverability for a vehicle of its size. The L3H2 variant benefits from a wider track compared to some other Master configurations, enhancing stability.
Market Reception & Comparison
The Renault Master III Phase III 2.3 dCi 135 L3H2 was generally well-received by commercial vehicle operators. Critics praised its spacious interior, practical features, and relatively low operating costs. Compared to rivals like the Fiat Ducato, Mercedes-Benz Sprinter, and Ford Transit, the Master offered a competitive combination of price, payload capacity, and fuel efficiency. The 135 hp engine was considered adequate for most applications, but some reviewers noted that the higher-output versions offered a more refined driving experience. Fuel economy figures of around 9.4 l/100km (25 mpg) were competitive within its class. Reliability was generally good, although some owners reported issues with the DPF system, a common concern with modern diesel engines.
Legacy
The Renault Master III Phase III 2.3 dCi 135 L3H2 remains a popular choice in the used commercial vehicle market. Its robust construction and relatively simple mechanicals contribute to its long-term reliability. The M9T engine, while not known for being particularly refined, is generally durable if properly maintained. The availability of spare parts is good, and maintenance costs are reasonable. The van’s spacious interior and high payload capacity continue to make it a practical option for businesses and individuals needing a versatile and dependable large van. However, potential buyers should be aware of the potential for DPF-related issues and ensure that the vehicle has been regularly serviced.
