The Renault D4F 780 is a 1,149 cc, inline‑four petrol engine produced between 2006 and 2012. It features a dual overhead camshaft (DOHC) design with 16 valves and sequential multi‑point fuel injection, delivering 55 kW (75 PS) and 105 Nm of torque. Its compact, lightweight architecture prioritizes fuel efficiency and agile urban performance.
Fitted primarily to the Clio III and Modus, the D4F 780 was engineered for responsive, economical city driving. Emissions compli…
All production years (2006–2012) meet Euro 4 standards; select 2010–2012 models may have Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Renault D4F 780 is a 1,149 cc inline‑four petrol engine engineered for supermini platforms (2006-2012). It combines DOHC 16-valve architecture with sequential multi-point fuel injection to deliver responsive low-end torque and frugal fuel consumption. Designed to meet Euro 4 (and some market-specific Euro 5) standards, it prioritizes urban efficiency and compact packaging.

The Renault D4F 780 was used across Renault's B-segment platforms with transverse mounting. This engine received minor ECU and emissions adaptations for different model years and trim levels, creating subtle power and torque variations. All adaptations are documented in OEM technical bulletins.
The D4F 780's primary reliability risk is exhaust camshaft lobe wear, with elevated incidence in high-mileage or poorly maintained engines. Renault internal data indicated this was a notable failure mode for engines exceeding 150,000 km without strict oil service adherence, while routine maintenance records show timing chain issues are comparatively rare. Neglecting oil changes and aggressive driving make using the correct lubricant and service intervals critical.
Analysis derived from Renault technical bulletins (2006-2012) and UK DVSA failure statistics (2010-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The D4F 780 is generally robust for its size and era, especially if serviced correctly. Its main weakness is potential exhaust camshaft wear in neglected or high-stress examples. With regular oil changes using the correct specification and sensible driving, it can easily surpass 200,000 km. Timing chain issues are uncommon.
The most frequent issues are exhaust camshaft lobe wear (causing a tapping noise), ignition coil pack failures (leading to misfires), and faulty coolant temperature sensors. Timing chain tensioner rattle can occur on very high-mileage engines. These are well-documented in Renault service information.
The D4F 780 1.2 16V engine was primarily used in the Renault Clio III (2006-2012) and the Renault Modus (2006-2012). It was also fitted to the Nissan Micra K13 (2010-2012) in certain markets, where it was slightly detuned to 80 PS.
Minor gains are possible via ECU remapping, typically adding 5-10 kW by optimizing ignition and fuel maps. Significant power increases are limited by the engine's small displacement and stock internals. Bolt-on modifications like an induction kit or exhaust offer minimal gains. Reliability should be prioritized over power.
Excellent for its time. In a Renault Clio 1.2 16V, expect combined figures around 5.5-6.0 L/100km (approx. 47-51 mpg UK). Real-world economy is heavily dependent on driving style, but its low weight and efficient design make it very economical for city and mixed driving.
Yes. The D4F 780 is an interference engine. If the timing chain fails or jumps significantly, the pistons can collide with the open valves, causing severe internal damage requiring a costly rebuild. This underscores the importance of addressing any timing chain noise promptly.
Renault specifies oil meeting RN0700 or RN0710 standards, typically a 5W-30 or 5W-40 synthetic or semi-synthetic. Using the correct specification is crucial for protecting the camshafts and ensuring proper lubrication. Change intervals should not exceed 15,000 km or 12 months.
