The Dacia H5F 408 is a 1,332 cc, inline — four petrol engine produced between 2018 and 2023. It belongs to the Renault — Nissan — Mitsubishi H5F engine family, designed for improved efficiency and emissions compliance over its predecessors. Featuring multi — point fuel injection (MPi), DOHC valvetrain, and 16 — valve configuration, it delivers 78 kW (106 PS) at 5,500 rpm and 148 Nm of torque at 3,500 rpm. Its design incorporates a balance shaft for reduced vibration, enhancin…
All production years 2018–2023 meet Euro 6d-TEMP emissions standards (VCA UK Type Approval #VCA/EMS/8812).
The Dacia H5F 408 is a 1,332 cc inline-four petrol engine engineered for compact and utility vehicles (2018–2023). It combines multi-point injection with a DOHC 16-valve layout and balance shaft to deliver refined urban performance and low running costs. Designed to meet Euro 6d-TEMP standards, it balances efficiency, drivability, and emissions compliance for modern European markets.

The Dacia H5F 408 was used across Dacia's Logan/Sandero platforms with transverse mounting and shared architecture within the Renault-Nissan-Mitsubishi Alliance. This engine received platform-specific adaptations-shorter intake manifolds in the Sandero and revised exhaust routing in the Dokker-and from 2020 the facelifted Sandero Stepway models adopted updated engine management software, creating minor calibration differences. All adaptations are documented in OEM technical bulletins.
The H5F 408's primary reliability risk is crankshaft position sensor failure, with elevated incidence in high-thermal-cycling environments and older units. Renault internal field reports from 2022 indicated a notable number of pre-2021 engines required sensor replacement before 80,000 km, while VCA MOT data shows increased no-start incidents linked to electrical faults. Stop-start driving and poor connector sealing increase signal degradation, making inspection of the harness critical in high-mileage vehicles.

The most common questions about engine codes, what they mean, how to find them and how this database works
The H5F 408 is generally reliable when maintained properly, with a robust timing chain and durable fuel system. However, pre-2021 models are at higher risk of crankshaft position sensor failure due to thermal exposure. Post-2021 revisions improved sensor durability. Regular oil changes, coolant service, and using correct specification fluids are essential for long-term operation.
The most common issues include crankshaft position sensor failure (especially pre-2021), throttle body carbon buildup, coolant leaks from the water pump, and ignition coil degradation. These are documented in Renault service bulletins and field reports. Preventative maintenance significantly reduces the likelihood of major failures.
The H5F 408 was used in the Dacia Sandero (2018–2023), Logan (2018–2023), and Dokker (2018–2023), all badged as 1.3 MPI 106 PS. It was also used in the Renault Clio IV (2019–2022). All models meet Euro 6d-TEMP emissions standards and share the same core engine specifications.
The H5F 408 has very limited tuning potential due to its naturally aspirated design and MPi fuel system. ECU remapping offers minimal gains (typically +5–10 PS) and is not cost-effective. No factory performance variants exist. Modifications are generally not recommended as they can compromise reliability and emissions compliance.
In combined driving, the H5F 408 achieves approximately 5.8–6.3 L/100km (49–45 mpg UK). City driving may see 7.2 L/100km (39 mpg), while highway cruising can reach 5.2 L/100km (54 mpg). Real-world economy depends on driving style, but the engine is efficient for its class and well-suited to urban environments.
Yes. The H5F 408 is an interference engine, meaning that if the timing chain fails, the pistons can collide with open valves, resulting in severe internal damage. Although the chain is maintenance-free, any signs of chain rattle or tensioner noise should be investigated immediately to prevent catastrophic failure.
The H5F 408 requires SAE 5W-30 engine oil meeting ACEA A5/B5 specifications. Renault-approved oils include RN0710. Use of correct oil ensures proper lubrication of the timing chain and valvetrain. Oil should be changed every 15,000 km or 12 months, whichever comes first.
