The Renault H5F 403 is a 1,197 cc, inline‑three turbocharged petrol engine produced between 2012 and 2018. It features direct fuel injection, a single — scroll turbocharger, and dual overhead camshafts (DOHC). This compact powerplant was designed to offer a blend of efficiency and responsiveness, delivering outputs between 88–103 kW (120–140 PS) and torque figures of 190–240 Nm.
Fitted primarily to the B‑segment Captur and Clio IV, the H5F 403 was engineered for urban a…
Production years 2012–2015 meet Euro 5 standards; 2016–2018 models meet Euro 6 standards .
The Renault H5F 403 is a 1,197 cc inline‑three turbocharged petrol engine engineered for subcompact SUVs and hatchbacks (2012-2018). It combines direct fuel injection with a single‑scroll turbocharger to deliver responsive performance and good fuel economy. Designed to meet Euro 5 and Euro 6 emissions standards, it balances urban agility with highway capability.

The Renault H5F 403 was used across Renault's B0 platform with transverse mounting. This engine received platform-specific adaptations-optimized engine mounts for the Captur and revised cooling for the Clio IV-and from 2016 the addition of a gasoline particulate filter for Euro 6 compliance, creating minor ECU and exhaust differences. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The H5F 403's primary documented concern is carbon buildup on intake valves, common to direct-injection engines. Renault technical notes indicate this is manageable with preventative maintenance, while owner reports suggest it is less severe than on some competitors. Vehicles with low annual mileage or predominantly short trips are most susceptible, making periodic cleaning or the use of fuel system cleaners advisable.

The most common questions about engine codes, what they mean, how to find them and how this database works
The H5F 403 is generally considered reliable with proper maintenance. Its main quirk is potential intake valve carbon buildup, common to direct-injection engines. Addressing this with periodic cleaning and using quality fuel ensures longevity. Major mechanical failures like timing chain breaks are rare. Regular oil changes are crucial for turbo health.
The most frequently reported issues are carbon buildup on intake valves, turbo actuator failures, and noisy high-pressure fuel pumps. Timing chain tensioner rattle can also occur on higher-mileage examples. These are well-documented in Renault's technical service bulletins and are generally repairable without engine replacement.
The H5F 403 1.2 TCe engine was used in the Renault Clio IV (2012-2018) and the first-generation Renault Captur (2013-2018). It was offered in two power outputs: TCe 120 (88 kW) and TCe 140 (103 kW). It was not used in Dacia or Nissan models under this specific code.
Aftermarket ECU tuning is common on the H5F-403 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Official combined figures range from 4.8 to 5.4 L/100km (52-48 mpg UK), depending on the model and year. Real-world consumption is typically 6.0-7.0 L/100km (47-40 mpg UK) in mixed driving. The TCe 120 is slightly more economical than the TCe 140 variant under normal driving conditions.
Yes. The H5F 403 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. Fortunately, the chain is robust and designed to last the engine's lifetime with proper oil maintenance.
Renault specifies a 5W-40 synthetic oil meeting the RN0710 standard. This is critical for protecting the turbocharger and ensuring proper lubrication of the timing chain. Using the correct oil and adhering to the 15,000 km or annual service interval is vital for engine longevity.
