The Renault F9Q 733 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2001 and 2006. It features a cast‑iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a variable geometry turbocharger (VGT). Power output ranged from 81 kW (110 PS) to 96 kW (130 PS), with torque figures between 270–300 Nm, providing strong pulling power for its class.
Fitted primarily to the Mégane II and Scénic II platforms, including variants like the 1.9 dCi 110 and 1.9 dCi 130, the F9Q 733 was engineered for a blend of fuel economy and responsive performance. Emissions compliance for most units was achieved through exhaust gas recirculation (EGR), meeting Euro 3 standards.
One documented reliability concern involves the high-pressure fuel pump, which can fail prematurely if fuel filters are not replaced at recommended intervals. This issue, referenced in Renault Technical Note MEG‑01‑03, is often linked to fuel contamination or water ingress. Later revisions incorporated minor updates to the pump's internal seals.
Production years 2001–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault F9Q 733 is a 1,870 cc inline‑four turbo‑diesel engineered for compact MPVs and hatchbacks (2001-2006). It combines a Bosch common‑rail fuel system with a single variable‑geometry turbocharger to deliver strong mid‑range torque and efficient highway cruising. Designed to meet Euro 3 standards, it prioritizes drivability and economy for its era.

The VGT turbo provides accessible torque for overtaking but demands strict 20,000 km fuel filter changes to protect the high-pressure pump. Renault RN0700/0710 (5W-40) oil is critical for turbo and injector longevity. Extended idling should be avoided to prevent EGR valve coking. The Bosch CP1 pump is sensitive to water and low-quality fuel; always use EN 590 standard diesel. Pre-emptive replacement of the fuel pressure regulator (per Renault Note MEG-01-03) is advised on high-mileage engines to avoid sudden pump failure. EGR systems require cleaning every 60,000 km to maintain performance.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Technical Note MEG-01-03). Equivalent to ACEA B3/B4.
Emissions: Euro 3 certification applies to all 2001-2006 F9Q 733 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. 96 kW output requires EN 590 fuel quality (Renault Group PT-2005).

The Renault F9Q 733 was used across Renault's Mégane II and Scénic II platforms with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the Scénic's raised ride height-and no significant facelift revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, below the exhaust manifold (Renault Service Manual 1.9 dCi). The 8th VIN digit typically indicates engine power output ('F' for 110 PS, 'G' for 130 PS). All F9Q 733 engines feature a black plastic cam cover with 'dCi' branding. Critical differentiation from the earlier F9Q 720: The 733 has a Garrett VGT turbo with an electronic actuator, while the 720 uses a simpler wastegate. Fuel injectors and high-pressure pumps are specific to the 733 variant and not interchangeable with other F9Q codes without ECU remapping.
The F9Q 733's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles with neglected fuel filter changes. Renault internal reports indicated a significant correlation between pump failures and extended service intervals, while owner data suggests EGR valve clogging is common in stop-start urban driving. Using low-quality fuel or skipping filter changes makes preventative maintenance critical.
Analysis derived from Renault technical bulletins (2003-2007) and UK DVSA failure statistics (2010-2020). Repair procedures should follow manufacturer guidelines.
