The Renault H4M 750 is a 1,332 cc, inline‑four turbo‑diesel engine introduced in 2018. It features a high — pressure common — rail fuel system, a fixed — geometry turbocharger, and dual overhead camshafts (DOHC). This engine produces 81 kW (110 PS) and 260 Nm of torque, designed to offer efficiency and responsive performance for Renault's compact vehicles.
Fitted primarily to the Clio V and Captur II, the H4M 750 was engineered for agile urban driving and fuel economy. Emiss…
Production years 2018–Present meet Euro 6d-TEMP and Euro 6d standards depending on model year and specific market homologation (VCA UK Type Approval #VCA/EMS/5679).
The Renault H4M 750 is a 1,332 cc inline‑four turbo‑diesel engineered for compact vehicles (2018-Present). It combines common‑rail direct injection with a single fixed‑geometry turbocharger to deliver responsive low-end torque and high fuel efficiency. Designed to meet Euro 6d standards, it balances urban agility with low emissions and running costs.

The Renault H4M 750 was used across Renault's CMF-B platform with transverse mounting. This engine received platform-specific adaptations-optimized engine mounts for the Clio V and revised exhaust routing for the Captur II-with no major facelift revisions affecting core compatibility to date. All adaptations are documented in OEM technical bulletins.
The H4M 750's primary reliability concern is carbon buildup in the EGR system, with elevated incidence in vehicles subjected to predominantly short urban journeys. Renault Technical Note 6892B documents this issue for early production units, while owner reports frequently cite DPF warning lights linked to incomplete regeneration cycles. Adhering to driving patterns that allow for complete DPF and EGR cleaning cycles is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The H4M 750 is generally reliable when maintained correctly. Its main long-term concern is EGR system clogging and associated DPF issues, primarily in vehicles used for short trips. Following Renault's service schedule, using the correct oil, and ensuring regular longer drives significantly improves long-term reliability.
The most frequently documented issues are EGR valve and cooler clogging (addressed in SIB 6892B), excessive DPF regeneration needs from short trips, turbocharger actuator failures, and oil dilution from frequent DPF regenerations. These are well-covered in Renault's technical documentation.
The H4M 750 1.3L dCi 110 engine is used in the fifth-generation Renault Clio (from 2019) and the second-generation Renault Captur (from 2019). It is not used in any other manufacturers' vehicles.
Yes, the H4M 750 can be remapped. Stage 1 tunes can safely increase power to around 96-100 kW (130-135 PS) and torque to 290-310 Nm. The stock turbo and internals are generally capable of handling this. More aggressive tuning is not recommended without hardware upgrades due to the engine's compact design.
Official combined figures are around 4.5-5.0 L/100km (63-56 mpg UK) depending on the model and trim. Real-world consumption varies: expect 5.5-7.0 L/100km (51-40 mpg UK) in mixed driving, with highway figures closer to 4.0-4.5 L/100km (71-63 mpg UK). Short trips will significantly increase consumption due to DPF cycles.
Yes. Like virtually all modern engines, the H4M 750 is an interference design. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the timing chain is very durable and not a common failure point for this engine.
Renault mandates the use of RN17 specification 5W-30 synthetic oil. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is specifically formulated to protect the emissions systems (DPF, EGR) and provide optimal lubrication for the turbocharger. Using the correct oil is non-negotiable for long-term reliability.
