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,…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F4R 795 is generally a dependable engine with proper maintenance. Its main weakness is the timing chain tensioner, which can wear out and cause noise. Addressing this issue promptly and adhering to oil change schedules allows these engines to reliably reach 200,000 km or more.
The most frequent issues are wear of the hydraulic timing chain tensioner (causing a cold-start rattle) and oil leaks from the valve cover gasket. Secondary concerns include coolant leaks from the plastic thermostat housing and ignition coil failures. These are well-documented in Renault service information.
The F4R 795 was used in the Renault Mégane II (Phase 2, 2005-2008), Scénic II (2005-2009), and Laguna II (Phase 2, 2005-2007). It was the 2.0 16V petrol engine producing 140 PS, found in various trim levels of these models.
Yes, modest gains are possible. Common modifications include a performance exhaust, high-flow air filter, and ECU remap, which might yield 10-15 additional PS. Significant power increases are limited by its naturally aspirated design and would require major engine work.
Real-world fuel economy varies by model and driving style. In a Mégane II, expect around 8.0-9.0 L/100km (31-35 mpg UK) in mixed driving. Highway cruising can see figures closer to 6.5 L/100km (43 mpg UK). The Scénic II, being heavier, will typically consume slightly more fuel.
Yes. The F4R 795 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. This makes addressing any timing chain noise critically important.
Renault specifies an oil meeting the RN0700 standard, typically a 5W-40 synthetic or semi-synthetic. Using the correct specification is vital for the hydraulic timing chain tensioner. Change intervals should not exceed 15,000 km or 12 months, whichever comes first.
