The Renault F4R 784 is a 1,998 cc, inline‑four petrol engine produced between 2001 and 2008. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection. In standard form, it delivered 103 kW (140 PS) and 191 Nm of torque, providing a balance of performance and refinement for its era.
Fitted to models such as the Mégane II and Scénic II, the F4R 784 was engineered for responsive everyday driving and motorway stability. Emissions compliance for its production period was primarily met through precise fuel metering and catalytic converter technology, aligning with Euro 3 and Euro 4 standards depending on the model year and market.
One documented service concern is premature wear of the exhaust camshaft lobes, particularly on higher-mileage units. This issue, referenced in Renault internal service communications, is often attributed to insufficient lubrication under sustained high-RPM operation. Renault addressed this in later production runs with revised camshaft metallurgy and updated lubrication specifications.
Production years 2001–2005 meet Euro 3 standards; 2006–2008 models meet Euro 4 standards depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault F4R 784 is a 1,998 cc inline‑four petrol engine engineered for compact MPVs and hatchbacks (2001-2008). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver smooth power delivery and adequate mid-range torque. Designed to meet Euro 3 and Euro 4 emissions standards, it offers a blend of performance and drivability for its class.

The naturally aspirated design offers linear power delivery but requires high-RPM operation for maximum performance, which can accelerate camshaft wear. Using the specified Renault RN0700 (5W-40) oil is critical for protecting the valvetrain, especially the exhaust cam lobes. Extended oil change intervals beyond 15,000 km or one year significantly increase the risk of premature wear. Vehicles used for frequent high-speed driving should have the camshaft condition inspected proactively. The timing chain is generally robust but tensioner wear can occur after 200,000 km.
Oil Specs: Requires Renault RN0700 (ACEA A3/B4) specification (Renault SIB F4R-02). ACEA A5/B5 oils are not recommended.
Emissions: Euro 3 certification applies to 2001–2005 models; Euro 4 applies to 2006–2008 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ECE R85 standards. Power output is consistent across model years (Renault TIS Doc. F4R-001).

The Renault F4R 784 was used across Renault's Mégane II and Scénic II platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping variations for different body styles-and no major facelift revisions that affect core mechanical compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault TIS F4R-001). The 8th digit of the VIN is 'F' for petrol engines in this family. The F4R 784 can be visually identified by its black plastic intake manifold and the "2.0 16V" badge on the engine cover. It is distinct from the turbocharged F4Rt by the absence of a turbocharger and intercooler piping. For service parts, the engine serial number prefix must be verified, as minor component revisions occurred during the production run.
The F4R 784's primary documented reliability concern is exhaust camshaft lobe wear, with elevated incidence in vehicles subjected to sustained high-RPM operation. Renault internal data indicates this issue was prevalent in early production batches, while owner reports frequently cite related lifter noise. Adherence to correct oil specification and change intervals is the most critical mitigating factor.
