The Renault Master III (Phase II), specifically the 2.3 dCi 125 horsepower automatic variant introduced in 2014, represents a significant iteration of Renault’s large van offering. Positioned as a workhorse for commercial applications, this version of the Master, designated L3H3 LH35, balances practicality with reasonable running costs. Production of this specific configuration ran from 2014 to 2016, falling within the broader lifespan of the third-generation Master (2010-2019). The L3H3 designation indicates a long wheelbase and high roof, maximizing cargo volume, while the LH35 denotes a gross vehicle weight rating of 3.5 tonnes – a common limit for commercial vehicles in Europe, and increasingly in other markets. This variant was primarily aimed at businesses requiring a large, reliable van for deliveries, tradespeople needing mobile workshops, and conversion specialists looking for a versatile base vehicle.

INTRODUCTION
The Renault Master III Phase II 2.3 dCi 125 Automatic, launched in 2014, built upon the foundation of the successful Master III series. This iteration benefited from refinements to the engine and transmission, as well as updated interior features. The ‘Phase II’ designation signifies these mid-life updates, aimed at improving efficiency and driver comfort. The 2.3 dCi engine, a mainstay of Renault’s commercial vehicle range, was paired with a six-speed automatic transmission, offering a more relaxed driving experience compared to the standard manual gearbox. The L3H3 body style, denoting a long wheelbase and high roof, provided a substantial 14.8 cubic meters of cargo space, making it ideal for a wide range of commercial applications. This particular variant occupied a middle ground in the Master lineup, offering a balance between performance, fuel economy, and price.
Powertrain & Engine Architecture
At the heart of the Master III 2.3 dCi 125 Automatic lies the M9T engine, a 2.3-liter inline four-cylinder diesel. This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The M9T is turbocharged and intercooled, enhancing power output and efficiency. The 125 horsepower peak is achieved at 3500 rpm, while the 310 Nm (228.64 lb-ft) of torque is readily available from 1500 rpm, providing good low-end pulling power. The six-speed automatic transmission, sourced from ZF, is a torque converter type, offering smooth gear changes and reducing driver fatigue. While not known for being the sportiest transmission, it was well-suited to the demands of commercial operation. The engine meets Euro 5 emission standards, incorporating a diesel particulate filter (DPF) to reduce harmful emissions.
Driving Characteristics
The 125 horsepower output, coupled with the automatic transmission, results in a driving experience focused on practicality rather than performance. Acceleration is adequate for most situations, but the van is not particularly quick, especially when fully loaded. The automatic transmission prioritizes smooth shifts and fuel efficiency, sometimes at the expense of responsiveness. Compared to the manual transmission versions, the automatic offers a more relaxed driving experience, particularly in urban traffic. The gear ratios are optimized for hauling loads, with a focus on maximizing torque at lower engine speeds. While higher-output versions of the Master (such as those with the 150hp engine) offer more spirited performance, the 125hp automatic provides a good balance between power and economy for typical commercial use.
Equipment & Trim Levels
The Renault Master III 2.3 dCi 125 Automatic, in its standard form, offered a functional but reasonably well-equipped interior. Standard features typically included air conditioning, a driver’s airbag, electric windows, and a basic audio system with USB connectivity. The cabin was designed with durability in mind, featuring hard-wearing plastics and robust upholstery. Optional extras included a passenger airbag, cruise control, rear parking sensors, and a more advanced infotainment system with navigation. Trim levels varied depending on the market, but generally, this variant sat in the mid-range, offering a step up from the basic ‘Chassis Cab’ models but lacking the premium features found in the higher-specification versions.
Chassis & Braking
The Master III utilizes a front-wheel-drive layout, contributing to a lower load floor and improved space utilization. The front suspension consists of independent McPherson struts with a coil spring and anti-roll bar, providing a comfortable ride. The rear suspension employs a leaf spring setup, chosen for its robustness and load-carrying capacity. Braking is handled by ventilated discs at the front and solid discs at the rear. The braking system is adequate for the vehicle’s weight, but drivers should be mindful of the increased stopping distances when the van is fully loaded. The steering is hydraulic, providing a reasonable level of assistance.
Market Reception & Comparison
The Renault Master III 2.3 dCi 125 Automatic was generally well-received by critics as a practical and reliable workhorse. Its fuel economy, averaging around 30-35 mpg in real-world conditions, was considered competitive for its class. However, some reviewers noted that the automatic transmission could feel sluggish at times, and the interior lacked the refinement of some of its rivals. Compared to the higher-output 150hp version, the 125hp model offered lower running costs but sacrificed some performance. Against competitors like the Fiat Ducato, Mercedes-Benz Sprinter, and Ford Transit, the Master offered a compelling combination of price, practicality, and reliability.
Legacy
The Renault Master III 2.3 dCi 125 Automatic has proven to be a durable and reliable van, with many examples still in service today. The M9T engine, while not without its quirks, is generally considered to be a robust unit, provided it receives regular maintenance. Common issues include DPF blockages (particularly on vehicles used for short journeys) and wear and tear on the turbocharger. On the used market, these vans represent good value for money, offering a large cargo capacity and reasonable running costs. However, potential buyers should carefully inspect the vehicle for signs of heavy use and ensure that the DPF has been properly maintained.
