The Renault F9Q 744 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2007 and 2011. It features a common rail direct injection system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form, it delivers 96 kW (130 PS) and 300 Nm of torque, providing strong low — rpm torque for everyday drivability.
Fitted to models such as the Mégane III, Scénic III, and Laguna III, the F9Q 744 was engineered for a balance of fuel economy, l…
Production years 2007–2011 meet Euro 4 standards .
The Renault F9Q 744 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2007-2011). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 4 standards, it balances everyday performance with economy.

The Renault F9Q 744 was used across Renault's C/D platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Laguna and revised exhaust routing in the Scénic-but no major facelift revisions occurred during its production, ensuring broad parts interchangeability. 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The F9Q 744 is generally robust with strong torque, but early models (2007-2008) are known for fuel pump failures. Later units and those maintained with high-quality fuel and regular oil changes (using RN0700/0710 spec) can be very reliable. Addressing the EGR/DPF system proactively is key to longevity.
The most frequent issues are high-pressure fuel pump failure (especially pre-2009), EGR valve/cooler clogging leading to DPF problems, and turbo actuator faults. Oil leaks from the rocker cover gasket are also common as the engine ages. These are covered in Renault service bulletins.
The F9Q 744 1.9 dCi 130 engine was primarily used in the Renault Mégane III (2008-2011), Scénic III (2009-2011), and Laguna III (2007-2010). It was also found in some Nissan Primera P12 models (2007-2009) sold in European markets.
Aftermarket ECU tuning is common on the F9Q-744 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Official combined figures are around 5.5 L/100km (51 mpg UK). Real-world consumption typically ranges from 6.0-7.0 L/100km (40-47 mpg UK) in mixed driving, depending on the vehicle (Mégane vs. Laguna) and driving style. Highway cruising can yield under 5.0 L/100km (56 mpg UK).
Yes. The F9Q 744 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-30 synthetic oil meeting the RN0700 or RN0710 standard. This is crucial for protecting the turbocharger, high-pressure fuel system, and emissions components. Using the correct oil and adhering to 15,000 km (or annual) change intervals is vital for engine health.
