The Renault D4F 782 is a 1,149 cc, inline‑four petrol engine produced between 2007 and 2014. It features a double overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection, delivering 55 kW (75 PS) with 105 Nm of torque. Its compact dimensions and light weight made it ideal for city car applications.
Fitted primarily to the Twingo II and Wind, the D4F 782 was engineered for urban agility and low running costs. It provided responsive low‑end power suitable…
Production years 2007–2009 meet Euro 4 standards; 2010–2014 models meet Euro 5 standards .
The Renault D4F 782 is a 1,149 cc inline‑four petrol engine engineered for city cars (2007-2014). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver responsive urban performance and fuel efficiency. Designed to meet Euro 4 and Euro 5 standards, it balances compact size with everyday usability.

The Renault D4F 782 was used across Renault's A-segment platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Wind for packaging-and from 2010 models featured updated engine management for Euro 5 compliance, creating minor ECU interchange limits. 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 D4F 782's primary reliability risk is exhaust camshaft lobe wear on early builds, with elevated incidence in high-mileage or poorly maintained vehicles. Renault internal reports noted a significant number of camshaft replacements under warranty for pre-2010 engines, while general owner feedback highlights timing chain tensioner wear after 150,000 km. Infrequent oil changes accelerate cam wear, making adherence to the RN0700 specification and service intervals critical.
Analysis derived from Renault technical bulletins (2007-2014) and owner-reported failure data (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 782 is generally robust, especially post-2010 models with the revised camshaft. Its main weakness is cam lobe wear on early engines. With strict adherence to oil changes using RN0700 5W-40 and timely replacement of the tensioner, it can easily exceed 200,000 km. Regular maintenance is key to longevity.
The most frequent issues are exhaust camshaft lobe wear (early engines), timing chain tensioner wear (high mileage), ignition coil failures, and throttle body carbon buildup. These are well-documented in Renault technical notes and widespread in owner communities.
The D4F 782 was primarily used in the Renault Twingo II (2007-2014) and the Renault Wind roadster (2010-2013). It was the standard 1.2 16V petrol engine for these models during their respective production runs.
Yes, but gains are modest. ECU remapping can yield 5-10 kW extra by optimizing ignition and fuel maps. Significant power increases require internal modifications (cams, head work) which are often uneconomical. Most tuning focuses on improving throttle response rather than peak power.
Excellent for its era. In a Twingo II 1.2 16V, expect around 6.5 L/100km (city) and 4.5 L/100km (highway), translating to roughly 43-52 mpg UK combined. Real-world economy depends heavily on driving style.
Yes. The D4F 782 is an interference engine. If the timing chain jumps or breaks, the pistons will collide with the open valves, causing catastrophic engine damage. This makes maintaining the timing chain and tensioner in good condition absolutely critical.
Renault mandates oil meeting the RN0700 specification, typically a 5W-40 synthetic or semi-synthetic. Using the correct oil is vital for protecting the camshafts and ensuring proper hydraulic tensioner operation. Change intervals should not exceed 15,000 km or 12 months.
