The Renault Master III Phase III, specifically the 2.3 dCi 135 horsepower panel van in L3H3 configuration, represents a significant iteration of Renault’s large van offering, introduced in 2019. This variant is positioned as a workhorse solution for businesses requiring substantial cargo capacity and reasonable running costs. The L3H3 designation indicates a long wheelbase and high roof, maximizing interior volume. It builds upon the established Master III platform (launched originally in 2010) with updates to meet stricter Euro 6d-Temp emissions standards and incorporate revised technology. This model primarily serves the European commercial vehicle market, competing with vans like the Fiat Ducato, Mercedes-Benz Sprinter, and Ford Transit.

Powertrain & Engine Architecture
The 2.3 dCi engine, identified by the M9T code, is a four-cylinder, inline diesel engine. It utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The 135 horsepower version employs a twin-turbocharger setup – a smaller turbo for responsiveness at low engine speeds and a larger turbo for increased power at higher RPMs. An intercooler is also present to cool the intake air, further enhancing performance and efficiency. The engine produces 360 Nm (265.52 lb.-ft.) of torque at 1500 rpm, providing ample pulling power for hauling heavy loads. This variant is paired with a six-speed manual transmission, chosen for its durability and cost-effectiveness in commercial applications. While an automated manual transmission (AMT) was available on some Master III models, it wasn’t commonly paired with this specific engine output.
Driving Characteristics
The 135 hp 2.3 dCi with a manual transmission offers a balance between performance and fuel economy. Acceleration is adequate for most commercial driving scenarios, but it’s not particularly sporty. The twin-turbo setup helps mitigate turbo lag, providing a relatively linear power delivery. The six-speed gearbox is well-matched to the engine’s characteristics, allowing for comfortable cruising at highway speeds. Compared to higher-output versions of the 2.3 dCi (170 hp), this variant feels less strained when fully loaded, but naturally lacks the same level of outright performance. The manual transmission provides greater driver control compared to the optional AMT, especially when navigating challenging terrain or towing. The leaf spring rear suspension, while robust, can result in a somewhat firm ride when unladen.
Equipment & Trim Levels
The Master III Phase III 2.3 dCi 135 L3H3 typically came with a functional, rather than luxurious, equipment level. Standard features generally included air conditioning, a basic audio system with USB connectivity, electric windows, and central locking. Safety equipment included ABS brakes, Electronic Stability Program (ESP), and driver and passenger airbags. Optional extras included a rearview camera, parking sensors, a touchscreen infotainment system with navigation, and cruise control. Interior trim was typically utilitarian, with durable plastic surfaces and cloth upholstery. The focus was on practicality and longevity rather than aesthetic refinement.
Chassis & Braking
The Master III utilizes a front-wheel-drive layout, contributing to a lower load floor and improved space utilization. The front suspension employs an independent McPherson strut design with coil springs and an anti-roll bar, providing reasonable handling and ride comfort. The rear suspension utilizes a robust leaf spring setup, designed to handle heavy loads. Braking is handled by ventilated discs at the front and solid discs at the rear. The braking system is generally effective, but the large weight of the vehicle requires a firm pedal input. The 16-inch steel wheels are standard, with alloy wheels available as an optional upgrade.
Market Reception & Comparison
The Renault Master III 2.3 dCi 135 L3H3 was generally well-received by commercial vehicle operators. Critics praised its spacious interior, robust construction, and reasonable fuel economy. The 135 hp engine was considered a good compromise for operators who didn’t require the outright performance of the higher-output versions. Compared to the 170 hp variant, the 135 hp model offered slightly better fuel economy and potentially lower maintenance costs. However, the 170 hp version was preferred by those who frequently carried heavy loads or drove on hilly terrain. The Master’s main competitors, such as the Ford Transit and Mercedes-Benz Sprinter, offered similar levels of performance and practicality, with the Renault often being positioned as a more affordable option.
Legacy
The M9T engine, while generally reliable, is known to require regular maintenance, particularly regarding the turbocharger and fuel injection system. The twin-turbo setup can be more complex and potentially more prone to failure than a single-turbo configuration. However, with proper servicing, these engines can accumulate high mileage. In the used market, the Master III 2.3 dCi 135 L3H3 remains a popular choice for businesses seeking a large, affordable van. Its spacious interior and reasonable running costs continue to make it a practical and cost-effective solution for a wide range of commercial applications. Parts availability is generally good, and the relatively simple mechanical design makes it accessible for independent mechanics.
