The Renault Master III (Phase II), specifically the 2.3 Energy dCi 170 horsepower panel van in L2H3 MH35 configuration, represents a significant iteration of Renault’s large van offering. Introduced in 2017 and continuing through 2018, this variant was a key component of the Phase II refresh of the third-generation Master, which began production in 2010. Positioned as a workhorse for commercial applications, the L2H3 MH35 offered a balance between cargo capacity, fuel efficiency, and performance within the Master lineup. It catered to businesses requiring a sizable, reliable van for deliveries, trades, or conversions. This model is primarily a European vehicle, though grey market imports can be found elsewhere.

INTRODUCTION
The Renault Master III Phase II 2.3 Energy dCi 170, in its L2H3 MH35 configuration, is a large panel van designed for commercial use. The “L2H3” designation refers to the van’s length and height – L2 indicating a medium length body, and H3 denoting a high roof. The “MH35” signifies a maximum authorized mass of 3.5 tonnes (approximately 7,716 lbs), a common weight class for commercial vehicles in Europe. This variant builds upon the foundation of the Master III, introduced in 2010, with updates to the engine, styling, and interior features in the Phase II refresh. It was a popular choice for businesses needing a versatile and spacious van for a variety of applications.
Powertrain & Engine Architecture
At the heart of the Master III 2.3 dCi 170 lies the M9T engine, a 2.3-liter inline four-cylinder diesel. This engine is characterized by its twin-turbocharger setup and common-rail direct fuel injection. The twin-turbo configuration, utilizing a small and a large turbocharger, aims to reduce turbo lag and provide a broader torque curve. The common-rail system, operating at very high pressures, ensures precise fuel delivery for optimized combustion and reduced emissions. The engine produces 170 horsepower at 3500 rpm and a substantial 380 Nm (280 lb-ft) of torque at just 1500 rpm. This torque output is crucial for hauling heavy loads and maintaining speed on inclines. The 6-speed manual transmission was standard, providing a good balance between fuel economy and drivability. The engine also incorporates a particulate filter to meet stringent Euro 6 emission standards, and a Start & Stop system to further improve fuel efficiency.
Driving Characteristics
The 170 horsepower and 380 Nm of torque provide adequate performance for a van of this size and weight. While not a sports van, the M9T engine delivers sufficient power for highway cruising and city driving, even when fully loaded. The manual transmission allows for precise control, and the gear ratios are well-suited for both fuel efficiency and hauling capability. Compared to lower-powered versions of the Master III, the 2.3 dCi 170 offers a noticeable improvement in acceleration and overall responsiveness. However, it doesn’t match the performance of some of the more powerful alternatives available in the commercial van segment. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen, but it contributes to the van’s high payload capacity.
Equipment & Trim Levels
The Renault Master III Phase II L2H3 MH35 was typically equipped with a functional, utilitarian interior. Standard features generally included a driver’s airbag, ABS brakes, power steering, and a basic audio system. The cabin was designed with practicality in mind, featuring durable materials and easy-to-clean surfaces. Trim levels varied depending on the market, but options often included air conditioning, electric windows, a passenger airbag, cruise control, and a rearview camera. The van’s focus was on providing a reliable and functional workspace, rather than luxurious amenities. The L2H3 configuration offered a generous cargo volume of 12.3 cubic meters (434.37 cu. ft.), making it suitable for a wide range of commercial applications.
Chassis & Braking
The Master III utilizes a front-wheel-drive layout, which contributes to its relatively low load floor height and good interior space utilization. The front suspension employs an independent McPherson strut design with coil springs and an anti-roll bar, providing a reasonable level of ride comfort and handling. The rear suspension utilizes a robust leaf spring setup, designed to handle heavy loads. The braking system consists of ventilated discs on the front wheels and solid discs on the rear. ABS (Anti-lock Braking System) is standard, enhancing safety during emergency braking situations. The steering is hydraulic power-assisted, providing a good balance between ease of use and road feel.
Market Reception & Comparison
The Renault Master III Phase II 2.3 dCi 170 was generally well-received by commercial vehicle operators. Critics praised its spacious interior, robust powertrain, and competitive fuel economy. Compared to other vans in its class, such as the Fiat Ducato, Mercedes-Benz Sprinter, and Volkswagen Crafter, the Master offered a good value proposition. The 170 horsepower engine provided a good balance between performance and fuel efficiency, making it a popular choice for businesses seeking a reliable and cost-effective van. However, some reviewers noted that the interior was somewhat basic compared to some of its competitors, and the ride quality could be improved when unladen.
Legacy
The Renault Master III, including the 2.3 Energy dCi 170 variant, has proven to be a durable and reliable workhorse. The M9T engine, while complex, is generally considered to be a robust unit when properly maintained. On the used market, these vans represent a relatively affordable option for businesses or individuals needing a large-capacity van. Common issues include wear and tear on the turbochargers and potential problems with the diesel particulate filter, particularly if the van has been primarily used for short trips. However, with regular servicing and preventative maintenance, the Master III 2.3 dCi 170 can provide many years of reliable service.
