The Renault K4M 752 is a 1,598 cc, inline‑four petrol engine produced between 2008 and 2015. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection, delivering outputs around 80 kW (108 PS) and 148 Nm of torque. Its variable valve timing system optimises the trade‑off between low‑end responsiveness and fuel economy for everyday urban and highway driving.
Fitted to models like the Clio III, Mégane III, and Scénic III, the K4M 752 was…
Production years 2008–2011 meet Euro 4 standards; 2012–2015 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Renault K4M 752 is a 1,598 cc inline‑four naturally aspirated petrol engine engineered for compact and family hatchbacks/MPVs (2008-2015). It combines multi‑point fuel injection with variable valve timing to deliver balanced performance and fuel efficiency. Designed to meet Euro 4 (and later Euro 5) standards, it prioritises reliability and low running costs for daily use.

The Renault K4M 752 was used across Renault's B/C platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the Scénic and revised intake manifolds in later Mégane facelifts-and from 2012 the adoption of updated camshafts, creating minor service part differences. All adaptations are documented in OEM technical bulletins.
The K4M 752's primary documented concern is exhaust camshaft lobe wear, with elevated incidence in high-mileage or frequently high-load vehicles. Renault internal reports noted this issue predominantly in pre-2012 builds, while owner feedback often cites ignition coil failures as a common electrical fault. Sustained high RPM use and infrequent oil changes accelerate cam wear, making adherence to service intervals critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Generally yes, the K4M 752 is known for robust mechanicals. The main caveat is potential exhaust camshaft wear in pre-2012 models under high stress or poor maintenance. Using the correct 5W-40 oil and adhering to service intervals greatly mitigates this risk, making it a dependable engine for high mileage.
The most frequent issues are ignition coil failures causing misfires, coolant leaks from the plastic thermostat housing, and timing chain tensioner rattle on cold start. For early models, exhaust camshaft lobe wear is a documented mechanical concern addressed in Renault service bulletins.
This 1.6L petrol engine was widely used in Renault's lineup from 2008-2015. Key models include the Clio III (2008-2012), Mégane III (2008-2015), Scénic III (2009-2015), and the Dacia Duster (2010-2015). It powered various 1.6 16v trim levels across these vehicles.
Minor gains are possible. The naturally aspirated K4M 752 responds modestly to ECU remaps or induction/exhaust upgrades, typically yielding 5-10 kW extra. Significant power increases require forced induction, which is complex and costly. It's best suited to its stock, economical tuning.
Real-world fuel economy is reasonable. Expect around 7.5-8.5 L/100km (33-38 mpg UK) in mixed driving for a Mégane or Scénic. Smaller, lighter Clios may achieve 6.5-7.5 L/100km (38-43 mpg UK). Figures vary significantly with driving style and vehicle condition.
Yes. The K4M 752 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 specifies a 5W-40 synthetic oil meeting the RN0700 standard. Using this specific oil, or an equivalent ACEA A3/B4 5W-40, is crucial for protecting the engine, particularly the camshafts, and ensuring longevity. Change intervals should not exceed 15,000 km or 12 months.
