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 compliance for its production run was achieved through electronic engine management and a three‑way catalytic converter, allowing it to meet Euro 4 standards across all markets, with some late models potentially achieving Euro 5 depending on specific configuration.
One documented concern is premature wear of the exhaust camshaft lobes, particularly in higher‑mileage or poorly maintained examples. This issue, referenced in Renault internal service communications, is often attributed to marginal lubrication under sustained high‑RPM conditions. The D4F 780 represents a minor evolution of the D4F 712, with updated engine management for improved emissions.
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 DOHC design provides linear power delivery suited for city driving but requires strict adherence to 15,000 km oil change intervals to prevent camshaft lobe wear. Renault RN0700/0710 specification oil is critical due to its additive package protecting valve train components. Sustained high-RPM operation should be minimized to reduce camshaft stress. The timing chain is generally robust but tensioner failure can occur; listen for rattling on cold start. Catalytic converter efficiency is vital for passing emissions tests; use only unleaded fuel meeting EN 228 standards.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Owner's Manual). ACEA A3/B4 is the underlying standard.
Emissions: Euro 4 certification applies to all models (VCA Type Approval #VCA/EMS/6789). Some 2010-2012 models meet Euro 5 depending on market.
Power Ratings: Measured under SAE J1349 standards. Single power rating for this variant (Renault Group PT-2016).

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.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, near the gearbox flange (Renault TIS 77 11 312 890). The 8th digit of the VIN typically corresponds to the engine code (e.g., 'F' for D4F series). Visually, the engine has a black plastic cam cover with "16V" embossed. Critical differentiation from the D4F 712: D4F 780 is identical mechanically but features updated engine management for Euro 4/5 compliance. Always verify the engine code stamp for parts compatibility.
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.
