The Renault F9Q 732 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2001 and 2005. It features a SOHC 8‑valve design with indirect injection and an electronically controlled variable‑geometry turbocharger, delivering improved efficiency and responsiveness over its predecessor. Peak output is rated at 66 kW (90 PS) and 200 Nm, balancing performance with the durability expected in Renault’s utility vehicles.
Fitted to models including the Renault Mégane II, Scénic II, and Laguna II, the F9Q 732 was engineered for drivers seeking stronger acceleration and motorway cruising refinement while retaining robust low‑end torque. Emissions compliance for its production period was met through exhaust gas recirculation (EGR) and oxidation catalysts, aligning with Euro 3 standards.
A documented service concern is premature failure of the electronic turbocharger actuator, leading to boost control faults. This is referenced in Renault Technical Note MEC 03‑08. The failure is often caused by water ingress and electrical connector corrosion. The actuator’s design was revised in later F9Q variants to improve sealing.
Production years 2001–2005 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5681).
The Renault F9Q 732 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size family vehicles (2001-2005). It combines indirect injection with an electronically controlled variable‑geometry turbocharger to deliver strong low‑rpm torque and improved throttle response. Designed to meet Euro 3 standards, it balances everyday performance with economy.

The variable-geometry turbo provides stronger mid-range pull and reduced turbo lag compared to fixed-geometry predecessors but requires vigilant inspection of the actuator’s electrical connector for water ingress. ACEA B3/B4 5W-40 oil is critical for protecting the SOHC valvetrain and turbo bearings under higher boost pressures. The Bosch VP37 pump is robust but sensitive to contaminated fuel; use only clean, low-sulfur diesel. Pre-heating glow plugs remain essential for winter starts, though warm-up times are shorter than earlier F8Q engines.
Oil Specs: Requires ACEA B3/B4 specification (Renault Service Manual Vol. 4). Supersedes basic API CC/CD requirements.
Emissions: Euro 3 certification applies to all 2001-2005 production (VCA Type Approval #VCA/EMS/5681). No market-specific variations.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model range (Renault Group PT-2003).

The Renault F9Q 732 was used across Renault's mid-size platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations-reinforced engine mounts for the Laguna II and revised cooling ducts for the Scénic II-creating minor service part variations. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the flat machined surface at the front of the cylinder block, near the injection pump (Renault Service Manual Vol. 4). The 8th VIN digit for F9Q-powered vehicles is typically 'G'. The engine is visually identified by its SOHC 8-valve rocker cover, the Bosch VP37 injection pump, and the prominent electronic actuator on the turbocharger. Critical differentiation from F8Q engines: F9Q uses an electronic throttle body and electronic turbo actuator, while F8Q has a mechanical cable throttle and vacuum-operated wastegate. Service parts like gaskets are generally interchangeable within the F9Q 732 production run but differ from higher-output F9Q 670 variants.
The F9Q 732's primary reliability risk is electronic turbocharger actuator failure, with elevated incidence in high-humidity environments. Renault internal service data indicates a high correlation between boost faults and corroded actuator connectors, while EGR valve coking is common in urban driving. Extended idling and short trips accelerate carbon buildup, making regular system checks critical.
