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…
Production years 2001–2006 meet Euro 3 standards .
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 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.
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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F9Q 733 can be reliable with meticulous maintenance, particularly regarding the fuel system. Its main weakness is the high-pressure pump, which fails if fuel filters are neglected. With strict adherence to service schedules and use of quality fuel and oil, these engines can exceed 300,000 km. The timing chain is generally robust.
The most frequent issues are high-pressure fuel pump failure, EGR valve/carbon buildup, turbo actuator faults, and leaking injector seals. These are well-documented in Renault service bulletins. Neglecting the 20,000 km fuel filter change is the primary cause of pump failure.
The F9Q 733 1.9 dCi engine was used in the Renault Mégane II (2002-2006) and Scénic II (2003-2006), specifically in the 110 PS and 130 PS variants. It was not used in the Laguna or other larger Renault models of that era, which used different F9Q codes.
Aftermarket ECU tuning is common on the F9Q-733 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.
Excellent for its time. A Mégane II 1.9 dCi 110 typically achieves 5.5 L/100km (city) and 4.0 L/100km (highway), or around 55 mpg UK combined. The more powerful 130 PS version is slightly thirstier but still returns 50-52 mpg UK on a mixed cycle with careful driving.
Yes. The F9Q 733 is an interference engine. If the timing chain were to fail (which is rare but possible with extreme neglect), the pistons would collide with the open valves, causing catastrophic internal engine damage requiring a full rebuild or replacement.
Renault specifies a 5W-40 synthetic oil meeting RN0700 or RN0710 standards. Using the correct specification is vital for protecting the turbocharger, high-pressure fuel pump, and preventing sludge. Change intervals should not exceed 20,000 km or 12 months.
