The Renault F9Q 717 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2001 and 2008. It features a SOHC 8‑valve design with indirect injection and a variable geometry turbocharger (VGT), delivering outputs around 81 kW (110 PS) and 240 Nm of torque. Its robust architecture offered improved efficiency over fixed-turbo predecessors while retaining mechanical simplicity.
Fitted to models such as the Mégane II, Scénic II, and Laguna II, the F9Q 717 was engineered for drivers seeking a balance of fuel economy, low-end torque, and motorway cruising comfort. Emissions compliance was met through exhaust gas recirculation (EGR) and, on later builds, a diesel particulate filter (DPF), allowing compliance with Euro 3 and select Euro 4 markets.
One documented service concern involves carbon buildup restricting the variable geometry turbocharger vanes, leading to boost control faults and reduced performance. This issue, referenced in Renault Technical Note MEC 0015, is often exacerbated by frequent short trips preventing the turbo from reaching optimal self-cleaning temperatures.
Production years 2001–2005 meet Euro 3 standards; 2006–2008 models may have Euro 4 compliance depending on market (VCA UK Type Approval #VCA/EMS/5681).
The Renault F9Q 717 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2001-2008). It combines indirect injection with a variable‑geometry turbocharger to deliver strong low‑rpm torque and improved efficiency over fixed-turbo variants. Designed to meet Euro 3 (and some Euro 4) standards, it balances everyday performance with economy.

The variable-geometry turbo provides strong low-RPM torque and improved efficiency but requires periodic high-load operation to prevent carbon buildup on the vanes. ACEA B3/B4 oil is critical for protecting the rotary injection pump and valve train. The SOHC chain is generally robust but should be inspected at major services. The VP37 pump demands clean, low-sulfur diesel to prevent internal wear. Pre-heating glow plugs for 5-10 seconds in cold weather is essential for reliable starting. Post-2005 models may feature a DPF, requiring specific driving patterns or regeneration procedures to avoid blockage.
Oil Specs: Requires ACEA B3/B4 specification (Renault Service Manual 6010A). Mineral or semi-synthetic 10W-40/15W-40 is typical.
Emissions: Euro 3 certification applies to 2001–2005 models; Euro 4 for select 2006–2008 models (VCA Type Approval #VCA/EMS/5681).
Power Ratings: Measured under EEC 80/1269 standards (Renault PT‑2001). Output is consistent across applications.

The Renault F9Q 717 was used across Renault's mid-size platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping for the Mégane versus the Laguna-creating no significant interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, adjacent to the fuel injection pump (Renault Service Manual 6010A). The 8th VIN digit often corresponds to the engine code (e.g., 'F' for F9Q series). Visually, the F9Q 717 is identified by its SOHC 8-valve head, Bosch VP37 injection pump mounted on the right side, and the variable geometry turbo with an electronic actuator (not vacuum). Differentiate from F8Q engines by the presence of the VGT and its electronic control unit. Service parts for the turbo actuator and injection pump are specific to the F9Q 717 build date.
The F9Q 717's primary reliability risk is variable geometry turbo (VGT) vane sticking due to carbon buildup, with elevated incidence in vehicles used predominantly for short urban trips. Renault technical notes indicate this was a common cause of power loss and diagnostic trouble codes, while its simple mechanical design otherwise offers good durability. Infrequent highway driving and infrequent oil changes make proactive maintenance critical.
