The Dacia H5F 404 is a 1,333 cc, inline — four petrol engine produced between 2019 and 2023. It belongs to the Renault — Nissan — Mitsubishi Alliance's H5F engine family, co — developed with Renault and Nissan. Featuring DOHC, 16 — valve architecture and multi — point fuel injection, it delivers 78 kW (106 PS) and 156 Nm of torque, offering improved performance and efficiency over previous naturally aspirated units.
Fitted to models such as the Dacia Sandero, Logan, and Dokker…
Production years 2019–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/6789).
The Dacia H5F 404 is a 1,333 cc inline-four petrol engine engineered for compact and utility vehicles (2019–2023). It combines multi-point fuel injection with dual overhead camshafts to deliver improved responsiveness and fuel economy. Designed to meet Euro 6d-TEMP emissions standards, it balances modern emissions compliance with cost-effective ownership.

The Dacia H5F 404 was used across Dacia's Global Access Platform with transverse mounting and shared with Renault under Alliance agreements. This engine received platform-specific adaptations-shorter intake manifolds in the Sandero and reinforced mounts in the Logan MCV-and from 2021 the facelifted Sandero Stepway adopted revised ECU mapping for improved cold-start emissions, creating calibration differences. All adaptations are documented in OEM technical bulletins.
The H5F 404's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in short-trip urban use. Internal Renault quality reports from 2022 indicated a measurable rate of pre-2021 engines requiring chain service before 120,000 km, while UK DVSA data links a notable share of emissions-related MOT failures to catalytic converter degradation in high-mileage examples. Frequent cold starts and extended idling increase guide stress, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The H5F 404 is generally reliable when maintained properly. Early models (2019-2020) had timing chain tensioner concerns, but post-2021 revisions resolved most issues. With regular oil changes (every 15,000 km) using SAE 5W-30 ACEA A5/B5 oil, these engines often exceed 200,000 km. Avoid short-trip driving without warm-up cycles to minimise carbon buildup and ensure longevity.
The main issues are timing chain tensioner wear (especially pre-2021), intake valve carbon buildup due to port injection, coolant leaks from the thermostat housing, and ignition coil failures. These are documented in Renault service bulletins. Catalytic converter degradation can occur on high-mileage vehicles with poor maintenance history.
The H5F 404 engine was used in the Dacia Sandero (SCe 110), Logan (SCe 110), and Dokker (SCe 110) from 2019 to 2023. It was also shared with Renault under the Alliance, appearing in the Renault Clio 1.3 TCE 110 (naturally aspirated version). All applications meet Euro 6d-TEMP emissions standards.
Limited tuning potential exists. ECU remaps can yield modest gains (~5-10 kW) by optimising fuel and ignition maps, but the naturally aspirated design and compression ratio limit output. Aftermarket exhausts or intake systems offer minimal benefit. Most owners prioritise reliability over performance, and significant modifications are not cost-effective for this engine.
In real-world driving, expect 6.2–7.8 L/100km (46–36 mpg UK) depending on model and driving style. The Sandero SCe 110 achieves approximately 6.0 L/100km (47 mpg UK) on mixed routes. Fuel economy benefits from the engine's lightweight design and low friction, but city driving with short trips reduces efficiency due to incomplete warm-up cycles.
Yes. The H5F 404 is an interference engine. If the timing chain fails or jumps, the pistons can contact the open valves, resulting in severe internal damage. This makes proper maintenance of the chain and tensioner critical. Any rattling noise at cold start should be investigated immediately to prevent catastrophic failure.
The manufacturer specifies SAE 5W-30 oil meeting ACEA A5/B5 standards. Renault-approved oils include RN0710 specification. Change intervals are up to 15,000 km under normal conditions. Using correct oil ensures proper timing chain lubrication and reduces wear on hydraulic tappets and valve train components.
