The Renault F9Q 736 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2007 and 2018. It features a cast‑iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a variable geometry turbocharger (VGT). Output ranges from 96 kW (130 PS) to 110 kW (150 PS), with peak torque of 300–320 Nm, providing strong pulling power for its vehicle class.
Fitted to models like the Mégane III, Scénic III, and Koleos, the F9Q 736 was engineered for a blend of refinement, mid-range torque, and respectable fuel economy. Emissions compliance for most variants was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 5 standards from its 2009 introduction.
A documented concern involves the high-pressure fuel pump, which can suffer premature wear leading to hard starting or loss of power, as noted in Renault Service Bulletin 8411A. This is often linked to fuel quality or inadequate lubrication. Renault addressed this in later production runs with revised pump internals and updated calibration.
Production years 2009–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678). Earlier pre-facelift applications may vary by specific market regulation.
The Renault F9Q 736 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size SUVs and MPVs (2007-2018). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong mid‑range torque and efficient highway cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The VGT turbo provides linear power delivery ideal for overtaking but requires strict adherence to 20,000 km oil change intervals using RN0720 specification to prevent turbo and injector wear. Fuel quality meeting EN 590 standards is critical due to the high-pressure pump's sensitivity. Extended idling should be minimized to reduce DPF soot loading. The EGR system demands periodic cleaning to maintain airflow and prevent fault codes. Post-2012 models feature a revised fuel pump; earlier units should follow the inspection protocol per Renault SIB 8411A.
Oil Specs: Requires Renault RN0720 (5W-30) specification (Renault SIB 8411A). Compatible with ACEA C3.
Emissions: Euro 5 certification applies to all documented F9Q 736 applications (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. 110 kW output requires EN 590 fuel quality (Renault TIS Doc. F9Q-003).

The Renault F9Q 736 was used across Renault's Mégane III/Scénic III platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Koleos for off-road durability-and from 2012 received a minor update with a revised high-pressure fuel pump, creating subtle service part differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, below the fuel injectors (Renault TIS F9Q-005). The 8th VIN digit typically indicates engine displacement ('9' for 1.9L dCi family). Pre-2012 engines have a silver Bosch CP3 pump with a black plastic top cover; post-2012 units feature a black pump body with a metal cover. Critical differentiation from earlier F9Q variants: The F9Q 736 uses a specific ECU map and has a DPF as standard. Service parts, particularly for the fuel system, require production date verification due to the 2012 pump update (Renault SIB 8411A).
The F9Q 736's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel or exceeding service intervals. Renault internal reports linked a notable number of failures to pre-2012 builds, while UK DVSA data shows DPF-related issues are common in urban-driven examples. Extended idling and short trips increase DPF and EGR stress, making fuel quality and maintenance critical.
Analysis derived from Renault technical bulletins (2010-2016) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
