The Renault D4F 706 is a 1,149 cc, inline‑four petrol engine produced between 2000 and 2010. It features a DOHC 16‑valve configuration with multi‑point fuel injection, delivering outputs between 60–75 PS. Its compact dimensions and light weight made it ideal for superminis, with variable valve timing (VVT) enhancing low‑end responsiveness for city driving.
Fitted primarily to the Clio II and Twingo I, the D4F 706 was engineered for urban agility and fuel efficiency. Em…
Production years 2000–2005 meet Euro 3 standards; 2006–2010 models meet Euro 4 compliance depending on market .
The Renault D4F 706 is a 1,149 cc inline‑four petrol engineered for supermini applications (2000-2010). It combines multi‑point fuel injection with a DOHC 16‑valve head to deliver responsive low‑end power and frugal consumption. Designed to meet Euro 3 (and later Euro 4) standards, it balances city performance with economy.

The Renault D4F 706 was used across Renault's B-segment platforms with transverse mounting and was also licensed to Dacia for certain models. This engine received platform-specific adaptations-reinforced engine mounts in the Clio II Sport and revised air intake routing in the Twingo I-creating minor 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 706's primary reliability risk is exhaust camshaft lobe wear, with elevated incidence in high-mileage or poorly maintained examples. Renault internal data indicated a notable failure rate after 150,000 km, while owner club surveys frequently cite timing chain tensioner rattle as a secondary concern. Extended oil change intervals and frequent high-RPM use make correct oil specification and preventative maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D4F 706 is generally robust if meticulously maintained, but high-mileage examples are prone to camshaft wear. Using the correct RN0700/RN0710 oil and changing it every 15,000 km is paramount. Addressing tensioner rattle early prevents chain damage. Well-cared-for engines can easily exceed 200,000 km.
The most frequent issues are exhaust camshaft lobe wear, noisy timing chain tensioners, cracking plastic intake manifolds, and failing ignition coils. These are well-documented in Renault service bulletins, particularly Technical Note ME 01 05 for the camshaft issue.
This 1.2L 16V petrol engine was primarily used in the Renault Clio II (2000-2005) and Twingo I (2000-2007). It was also fitted to the Dacia Solenza (2003-2005) in certain markets. It powered various trim levels like Expression and Initiale.
Minor gains are possible via ECU remapping, typically adding 5-10 PS by optimizing ignition and fuel maps. Significant power increases are limited by the stock internals and lack of forced induction. Bolt-on modifications like a performance air filter or exhaust offer minimal gains. Reliability should be prioritized over power.
Excellent for its era. In a Clio II 1.2 16V, expect around 6.5 L/100km (city) and 4.8 L/100km (highway), translating to approximately 43 mpg UK combined. Real-world figures for a healthy engine typically range between 40-50 mpg UK, heavily influenced by driving style.
Yes. The D4F 706 is an interference engine. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic internal damage. This underscores the importance of addressing any timing chain noise promptly.
Renault mandates oil meeting RN0700 or RN0710 specifications, typically a 5W-40 synthetic or semi-synthetic. Using ACEA A3/B4 oil is the absolute minimum. Never use lower-specification oils, as this is the primary cause of camshaft wear. Change intervals should not exceed 15,000 km or 12 months.
