The Renault F4R 795 is a 1,998 cc, inline‑four petrol engine produced between 2005 and 2015. It features a dual overhead camshaft (DOHC) design with 16 valves and sequential multi‑point fuel injection. In standard European specification, it produced 103 kW (140 PS) and 195 Nm of torque, offering a refined and economical powertrain for its class.
Fitted to models such as the Renault Mégane II (Phase 2), Scénic II, and Laguna II (Phase 2), the F4R 795 was engineered for smooth, quiet operation and low running costs. Emissions compliance for its production run was met through electronic engine management and catalytic converters, aligning with Euro 4 standards.
One documented service concern involves premature wear of the timing chain tensioner, which can lead to chain noise or, in extreme cases, timing jump. This issue, referenced in Renault service documentation, is often linked to extended oil change intervals. Later F4R 795 variants incorporated revised tensioner designs to improve durability.
Production years 2005–2015 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5679).
The Renault F4R 795 is a 1,998 cc inline‑four petrol engine engineered for compact and mid‑size MPVs and sedans (2005-2015). It combines DOHC 16-valve architecture with sequential multi-point fuel injection to deliver smooth, linear power delivery. Designed to meet Euro 4 standards, it balances everyday drivability with fuel efficiency.

The naturally aspirated design provides predictable, linear power but requires regular timing chain tensioner checks to prevent noise or wear. Renault RN0700 (5W-40) oil is critical for maintaining hydraulic tensioner function and valve train longevity. The Siemens injection system is generally robust but sensitive to fuel quality; using premium unleaded is recommended. The timing chain tensioner is a known wear item; failure typically triggers a rattle on cold start and requires replacement per Renault service procedure.
Oil Specs: Requires Renault RN0700 (ACEA A3/B4) specification (Renault Owner's Manual).
Emissions: Euro 4 certification applies to all 2005–2015 F4R 795 models (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under ECE R85 standards. Output figures are for standard European specification (Renault TIS Doc. F4R-003).

ECE Regulation No. 85: Engine Power Measurement
The Renault F4R 795 was used across Renault's Mégane II and Laguna II platforms with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the Scénic II-creating minor interchange considerations. 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-003). The 8th VIN digit for Mégane II models indicates engine type ('F' for F4R family). The F4R 795 can be visually identified by its black plastic intake manifold and Siemens engine management components. Critical differentiation from the F4R 767: F4R 795 has a revised timing chain cover and tensioner assembly. Service parts for the cylinder head are generally consistent across F4R 795 applications, but ancillary brackets may differ between models.
The F4R 795's primary reliability concern is wear of the hydraulic timing chain tensioner, with elevated incidence after 120,000 km. Renault internal service data indicates this is a common replacement item, while valve cover gasket leaks are a secondary concern for high-mileage examples. Adherence to oil change intervals is critical for long-term timing system health.
