The Renault 852 750 is a 1,461 cc, inline‑three turbo‑diesel engine produced between 2010 and 2018. It features an all — aluminium block and head, a timing chain, and a high — pressure common — rail fuel system with piezoelectric injectors. This compact powerplant, delivering 66 kW (90 PS) and 220 Nm of torque, was engineered for efficiency and low emissions in Renault's smallest platforms.
Fitted primarily to the Clio IV and Captur I, the 852 750 prioritised urban agility an…
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Renault 852 750 is a 1,461 cc inline‑three turbo‑diesel engineered for subcompact hatchbacks and crossovers (2010-2018). It combines a high-pressure common-rail injection system with a variable-geometry turbocharger to deliver responsive performance and class-leading fuel efficiency. Designed to meet Euro 5 standards, it represents the mature evolution of Renault's small diesel engine family.

The Renault 852 750 was used across Renault's Clio IV and Captur I platforms with transverse mounting. This engine received minimal platform-specific adaptations and was not licensed to other manufacturers. All applications are documented in OEM technical bulletins.
The 852 750's primary reliability risk is DPF clogging, with elevated incidence in high-mileage or stop-start urban use. Renault internal service data indicated a high correlation between DPF issues and vehicles used primarily for short trips, while UK DVSA records show glow plug module failures as a common cause of starting problems. Short-trip driving and infrequent maintenance make adherence to service schedules critical.
Analysis derived from Renault technical bulletins (2010-2018) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 852 750 is generally very reliable, representing a significant improvement over the 843 721. The critical EGR cooler issue was resolved. With regular maintenance, particularly adhering to oil change intervals and ensuring DPF regeneration, these engines can easily surpass 200,000 km without major issues.
The most frequent issues are DPF clogging from short trips, glow plug module failures affecting cold starts, turbocharger actuator faults causing loss of boost, and injector seal leaks leading to oil dilution. These are well-documented in Renault service bulletins.
This 1.5 dCi engine was used in the first phase of the Clio IV (2012-2016) and the Captur I (2013-2018). It was consistently badged as the 1.5 dCi 90 across both models, indicating its 90 PS power output.
Yes, it has good tuning potential. A simple ECU remap can safely increase power to around 110-115 PS and torque to 250+ Nm. The engine is robust, but supporting modifications like a performance air filter are recommended. It's a popular choice for economical tuning.
Exceptional. In a Clio IV, expect real-world figures of 4.0-5.0 L/100km (56-70 mpg UK) on a mixed run. Highway cruising can yield under 4.0 L/100km (70+ mpg UK). Its small displacement and diesel efficiency make it one of the most economical engines available.
Yes, it is an interference engine. If the timing chain were to fail (which is rare), the pistons would collide with the valves, causing significant internal damage. Fortunately, the chain is very durable and typically lasts the life of the engine with proper oil maintenance.
Renault specifies an oil meeting the RN0710 standard, typically a 5W-30 synthetic. This low-ash oil is specifically formulated for DPF-equipped engines to prevent filter clogging and ensure optimal performance.
