The Renault F4R 792 is a 1,998 cc, inline‑four petrol engine produced between 2008 and 2016. It features a dual overhead camshaft (DOHC) design with 16 valves and sequential multi‑point fuel injection. This naturally aspirated unit delivered 103 kW (140 PS) and 195 Nm of torque, engineered for smooth, linear power delivery across the rev range.
Fitted primarily to the Mégane III and Scénic III, the F4R 792 was designed for refined, everyday driving with an emphasis on low — t…
Production years 2008–2010 meet Euro 4 standards; 2011–2016 models meet Euro 5 standards .
The Renault F4R 792 is a 1,998 cc inline‑four petrol engine engineered for compact family vehicles (2008-2016). It combines DOHC 16-valve architecture with variable valve timing to deliver smooth, predictable power and enhanced fuel efficiency. Designed to meet Euro 4 and Euro 5 emissions standards, it offers a balance of performance and environmental compliance for its era.

The Renault F4R 792 was used across Renault's Mégane III and Scénic III platforms with transverse mounting. This engine received minor ECU updates for the 2012 facelift, but no major mechanical revisions affecting core compatibility occurred during its production run. 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F4R 792 is generally reliable, but the VVT solenoid is a known weak point, especially if oil changes are neglected. Using the correct Renault RN0700/0710 oil and adhering to service intervals significantly reduces the risk of failure. With proper maintenance, these engines can reliably exceed 200,000 km.
The most frequent issues are VVT solenoid failure, ignition coil pack failures, coolant leaks from the thermostat housing, and inlet manifold flap motor faults. These are well-documented in Renault service bulletins and owner communities.
The F4R 792 was primarily used in the third-generation Renault Mégane (2008-2016) and Scénic (2009-2016), specifically in the 2.0 16V petrol variants. It was not used in any other manufacturers' vehicles under license.
Yes, but gains are modest. An ECU remap can yield around +10-15 kW by optimizing ignition and fuel maps. More significant power requires hardware like performance cams, exhaust, and intake, which is costly. It's better suited to improving drivability than major power increases.
Real-world fuel economy is moderate. Expect around 9.0 L/100km (31 mpg UK) in urban driving and 6.0 L/100km (47 mpg UK) on the highway for a Mégane III. Combined figures typically range from 38-42 mpg UK, depending heavily on driving style and vehicle condition.
Yes. The F4R 792 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Renault mandates oil meeting RN0700 or RN0710 specifications, typically a 5W-40 synthetic or semi-synthetic. Using ACEA A3/B4 oil is the minimum requirement. Correct oil is crucial for preventing VVT solenoid issues and ensuring overall engine health.
