The Renault F9Q 674 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2001 and 2008. It marked a significant evolution from its predecessor, featuring common‑rail direct injection, a variable‑geometry turbocharger (VGT), and dual overhead camshafts (DOHC). This technology delivered outputs around 81 kW (110 PS) and 240 Nm of torque, providing a marked improvement in refinement and responsiveness over indirect injection units.

Production years 2001–2004 meet Euro 3 standards; 2005–2008 models may have Euro 4 compliance depending on market .
The Renault F9Q 674 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2001-2008). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong mid‑range torque and improved fuel efficiency. Designed to meet Euro 3 (and some market‑specific Euro 4) standards, it offers a balance of performance and economy.

The Renault F9Q 674 was used across Renault's Mégane/Scénic platforms with transverse mounting and was not licensed to other manufacturers. This engine received minimal platform-specific adaptations and from 2005 the facelifted Laguna II models adopted minor ECU revisions for emissions, creating subtle interchange limits. 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 674's primary reliability risk is dual-mass flywheel (DMF) failure, with elevated incidence in vehicles subjected to aggressive driving or frequent stop-start cycles. Renault technical notes document this as a common service item, while its electronically controlled systems generally ensure good long-term durability with basic maintenance. Adherence to oil change intervals and using quality fuel are critical for minimizing injector and turbo wear.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, the F9Q 674 is generally reliable long-term if basic maintenance is followed. Its main weakness is the dual-mass flywheel, which can fail prematurely with aggressive driving. Regular oil changes and using quality fuel are key to protecting the common-rail system and turbocharger for long-term durability.
The most common issues are failing dual-mass flywheels causing vibration, clogged EGR valves and coolers, failures in the high-pressure fuel pump or injectors, and problems with the variable-geometry turbo actuator. These are well-documented in Renault service information.
The F9Q 674 was used in the second-generation Renault Mégane (BM/CM, 2002-2008), Scénic (JM, 2003-2008), and Laguna (BG, 2001-2007), typically badged as the '1.9 dCi 110'. It was not used in the Kangoo or Clio of that era.
Aftermarket ECU tuning is common on the F9Q-674 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.
Fuel economy is very good for its era. Expect around 6.0-7.0 L/100km (40-47 mpg UK) combined in a Mégane or Scénic. Real-world figures vary with driving style, with highway driving yielding the best results. The common-rail system contributes to its efficiency.
Yes. The F9Q 674 is an interference engine. If the timing chain were to fail or jump, the pistons and valves will collide, causing severe internal engine damage. This makes regular inspection of the timing chain tensioner and guides critical.
Renault specifies an oil meeting ACEA B3 or B4 standards. A 5W-40 viscosity is typical. Using a quality diesel-specific oil and changing it every 15,000 km is crucial for protecting the high-pressure fuel system, turbocharger, and minimizing soot buildup in the engine.
