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, low-end pulling power, and refined operation. Emissions compliance was achieved through exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting Euro 4 standards for its production period.
One documented concern is premature failure of the high-pressure fuel pump, potentially leading to sudden engine shutdown. This issue, referenced in Renault Service Bulletin MEG‑07‑01, is often linked to fuel contamination or inadequate lubrication from low-quality diesel. Renault addressed this in later production runs with revised pump internals and stricter fuel filtration.
Production years 2007–2011 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
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 VGT turbo provides responsive low-end torque ideal for urban and highway driving but requires strict adherence to 15,000 km oil change intervals using Renault RN0700/0710 specification oil to prevent turbo and chain wear. Ultra-low-sulfur diesel (ULSD) meeting EN 590 standards is mandatory to protect the high-pressure fuel pump and injectors. The EGR/DPF system demands regular highway driving cycles for passive regeneration; frequent short trips can lead to filter clogging and limp mode. Pre-2009 models should have the fuel pump inspected per Renault SIB MEG-07-01 if experiencing hesitation or stalling.
Oil Specs: Requires Renault RN0700 or RN0710 (5W-30) specification (Renault Owner's Manual). Equivalent to ACEA C3.
Emissions: Euro 4 certification applies to all 2007-2011 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Renault TIS Doc. F9Q-003).

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.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Renault TIS F9Q-005). The 8th VIN digit typically corresponds to the engine code ('F' for F9Q series). Visually, the engine features a black plastic cam cover with 'dCi 130' branding. Critical differentiation from the earlier F9Q 740: The 744 variant has a Siemens VDO ECU with a 96-pin connector, while the 740 uses a Bosch ECU. Fuel pump part numbers are not interchangeable between early and late 744 builds without verifying the revision level per SIB MEG-07-01.
The F9Q 744's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. Renault internal reports from 2010 indicated a significant number of pump replacements under warranty for early builds, while UK DVSA data shows DPF-related faults as the second most common MOT failure for diesel Méganes of this era. Infrequent highway driving and neglecting oil changes accelerate EGR/DPF clogging and turbo wear, making fuel quality and maintenance critical.
