The Renault Master III (Phase II), specifically the 2.3 dCi 170 horsepower panel van in L1H2 SM33 automatic configuration, represents a significant iteration of Renault’s large van offering. Produced from 2017 to 2018, this variant was aimed at commercial users requiring a balance of performance, efficiency, and practicality. It falls within the broader Master III generation (introduced in 2010 and facelifted in 2014), sharing the same platform and core design but distinguished by its engine output and transmission choice. The L1H2 designation refers to the van’s length and roof height, indicating a relatively compact footprint within the Master range, making it suitable for urban deliveries and service applications.

INTRODUCTION
The Renault Master III Phase II 2.3 dCi 170 Automatic (L1H2 SM33) is a front-wheel-drive, diesel-powered panel van designed for commercial applications. Introduced as part of the facelifted Master III range in 2017, it offered a step up in power and convenience compared to lower-spec models. The “L1H2” designation signifies a relatively compact van size – ‘L1’ denoting a shorter wheelbase and ‘H2’ indicating a medium roof height. The ‘SM33’ trim level typically represents a mid-range specification, balancing essential features with affordability. This variant aimed to appeal to businesses needing a versatile van for deliveries, mobile workshops, or conversions.
Powertrain & Engine Architecture
At the heart of this Master variant lies the M9T 2.3-liter four-cylinder diesel engine. This engine is a common-rail direct injection (CDI) unit, benefiting from twin-turbocharging and an intercooler to enhance power and torque. The twin-turbo setup allows for reduced turbo lag and a broader powerband. The engine produces 170 horsepower at 3500 rpm and a substantial 380 Nm (280.27 lb.-ft.) of torque at just 1500 rpm. This torque output is particularly beneficial for hauling loads and navigating urban environments. The engine meets Euro 6 emission standards, incorporating a diesel particulate filter (DPF) and selective catalytic reduction (SCR) systems to minimize harmful emissions. Paired with the engine is a six-speed automatic transmission, providing smoother gear changes and reduced driver fatigue compared to a manual gearbox. This automatic transmission is electronically controlled, adapting shift points based on driving conditions and load.
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 2.3 dCi engine delivers brisk acceleration, especially when unladen. The automatic transmission contributes to a relaxed driving experience, particularly in stop-and-go traffic. Compared to the lower-powered 125 hp version, the 170 hp model offers a noticeable improvement in responsiveness, especially when fully loaded or climbing hills. The front-wheel-drive configuration provides good traction in most conditions, although it can struggle on slippery surfaces with a heavy load. The gear ratios are tuned for efficiency and usability, prioritizing torque delivery over outright speed. The automatic transmission generally shifts smoothly, but can occasionally feel hesitant during quick downshifts.
Equipment & Trim Levels
The SM33 trim level typically included features such as air conditioning, a basic audio system with USB connectivity, electric windows, and central locking. Safety features included ABS brakes, electronic stability control (ESC), and driver and passenger airbags. Optional extras available for this trim could include a rearview camera, parking sensors, upgraded audio systems, and navigation systems. Interior upholstery was typically durable cloth, designed for commercial use. The dashboard layout is functional and straightforward, prioritizing practicality over aesthetics. The cabin offers a reasonable level of comfort for the driver and passengers, although it is primarily focused on providing a work-oriented environment.
Chassis & Braking
The Renault Master III utilizes a front-wheel-drive chassis with independent McPherson strut suspension at the front and a leaf spring suspension at the rear. The leaf spring rear suspension is a cost-effective solution for handling heavier loads, but it can result in a slightly firmer ride compared to a more sophisticated independent suspension setup. The front brakes are ventilated discs measuring 302×28 mm, while the rear brakes are solid discs measuring 305×12 mm. This braking system provides adequate stopping power for the van’s weight and performance. The van rides on 16-inch steel wheels, typically fitted with 225/65 R16 tires.
Market Reception & Comparison
The Renault Master III 2.3 dCi 170 Automatic was generally well-received by critics as a capable and practical commercial vehicle. It was praised for its strong engine, comfortable ride (considering its class), and relatively low running costs. Compared to the lower-powered 1.3-liter engine options, the 2.3 dCi offered a significant performance advantage, making it suitable for more demanding applications. Fuel economy was competitive for its class, averaging around 32.7 mpg in combined driving. Reliability was generally good, although some owners reported issues with the DPF system, a common problem with modern diesel engines. Compared to rivals like the Fiat Ducato and Mercedes-Benz Sprinter, the Master offered a good balance of price, performance, and features.
Legacy
The Renault Master III 2.3 dCi 170 Automatic has proven to be a relatively durable and reliable workhorse in the used vehicle market. The M9T engine, while not without its quirks, is generally considered robust when properly maintained. The automatic transmission has also proven to be fairly reliable. However, potential buyers should be aware of the potential for DPF issues and ensure that the vehicle has been regularly serviced. Today, these vans are commonly found in service with small businesses, delivery companies, and as converted campervans. Their relatively affordable price and practical design continue to make them a popular choice for those needing a versatile and dependable large van.
