The Renault H5F 412 is a 1,332 cc, inline‑four turbocharged petrol engine introduced in 2015 for compact and subcompact applications. It features direct fuel injection, a twin — scroll turbocharger, and dual overhead camshafts (DOHC) with variable valve timing. Producing 103 kW (140 PS) and 240 Nm of torque, its compact displacement enables agile urban drivability while maintaining highway efficiency.
Fitted primarily to the Renault Mégane IV and Nissan Qashqai II, t…
All production years (2015–Present) meet at least Euro 6b standards; post-2018 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/EMS/2345).
The Renault H5F 412 is a 1,332 cc inline‑four turbo‑petrol engineered for compact vehicles (2015-Present). It combines direct injection with a twin-scroll turbocharger to deliver responsive low‑end torque and efficient urban commuting. Designed to meet Euro 6b and later Euro 6d-TEMP standards, it balances agility with emissions compliance.

The Renault H5F 412 was developed for Renault's Mégane IV platform with transverse mounting and is shared with Nissan for the Qashqai II. This engine received platform-specific adaptations-reinforced engine mounts for dynamic handling-and no significant facelift revisions affecting core compatibility to date. The partnership is part of the Renault-Nissan-Mitsubishi Alliance powertrain strategy. All adaptations are documented in OEM technical bulletins.
The H5F 412's primary reliability risk is intake valve carbon buildup, with elevated incidence in vehicles used predominantly for short urban trips. Renault internal service data indicates this is the leading cause of misfire complaints, while UK DVSA records show catalytic converter efficiency faults are common in high-mileage examples. Direct injection and infrequent highway driving make adherence to recommended cleaning intervals critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The H5F 412 is generally robust for daily driving, with its main vulnerability being carbon buildup on intake valves due to its direct injection design. With proper maintenance, use of correct RN07 oil, and periodic intake cleaning (every 60,000-80,000 km), it can achieve high mileages. Adhering to Renault's service schedule and using premium fuel is crucial for longevity.
The most frequent issues are intake valve carbon buildup causing misfires, turbocharger wastegate rattle, high-pressure fuel pump failure, and PCV/oil separator clogging leading to oil consumption. These are well-documented in Renault service bulletins and relate primarily to the engine's direct injection technology and turbocharging system.
The H5F 412 is primarily found in the Renault Mégane IV hatchback and estate from 2015 onwards, badged as the TCe 140. It is also used in the Nissan Qashqai II (J11), where it is designated as the DIG-T 140, reflecting minor ECU tuning differences within the Renault-Nissan alliance.
Yes, ECU remapping is very popular and can yield gains of 25-35 kW and 50-70 Nm. The engine's internals are quite strong, and the turbo has ample headroom. However, pushing beyond stock outputs increases stress on the turbo, fuel pump, and clutch. Any tuning should be approached cautiously and paired with regular maintenance checks.
Official combined figures for the Renault Mégane are around 5.5-6.0 L/100km (47-51 mpg UK). Real-world economy varies with load and driving style. Unladen highway driving can achieve ~4.8 L/100km (59 mpg UK), while aggressive urban driving may see 7.5 L/100km (38 mpg UK) or higher, especially if short trips prevent optimal engine warm-up.
Yes. The H5F 412 is an interference engine. If the timing chain were to fail or jump timing, the pistons would collide with the open valves, resulting in catastrophic internal engine damage requiring a full rebuild or replacement.
Renault mandates the use of RN07 specification 5W-30 synthetic oil. This low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is essential for protecting the turbocharger and catalytic converter. Using non-compliant oil will void the warranty and accelerate component wear.
