The Renault F9Q 758 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2006 and 2010. It features a cast‑iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a variable geometry turbocharger (VGT). Power output is rated at 96 kW (130 PS), delivering 300 Nm of torque, providing strong low-end pull and highway efficiency.
Fitted primarily to the Mégane II facelift and Scénic II facelift platforms, including the 1.9 dCi 130 variant, the F9Q 758 was engineered for responsive performance and improved refinement over its predecessor. Emissions compliance for all units was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 4 standards.
One documented reliability concern involves premature failure of the DPF pressure differential sensor, which can trigger false regeneration cycles or limp mode. This issue, referenced in Renault Technical Note MEG‑02‑08, is often linked to sensor contamination from soot or moisture ingress. The engine also received minor ECU software updates to optimize DPF regeneration logic.
Production years 2006–2010 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5679).
The Renault F9Q 758 is a 1,870 cc inline‑four turbo‑diesel engineered for compact MPVs and hatchbacks (2006-2010). 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 4 standards, it prioritizes drivability and economy with enhanced emissions control.

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. The DPF system requires regular highway driving to complete passive regenerations; frequent short trips can lead to soot overload and sensor faults per Renault Note MEG-02-08. EGR systems require cleaning every 60,000 km to maintain performance.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Technical Note MEG-02-08). Equivalent to ACEA B3/B4.
Emissions: Euro 4 certification applies to all 2006-2010 F9Q 758 models (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under SAE J1349 standards. 96 kW output requires EN 590 fuel quality (Renault Group PT-2008).

The Renault F9Q 758 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 ('G' for 130 PS). All F9Q 758 engines feature a black plastic cam cover with 'dCi' branding and a DPF filter in the exhaust system. Critical differentiation from the earlier F9Q 733: The 758 is exclusively paired with a DPF and has a slightly different ECU calibration for emissions control. Fuel injectors and sensors are specific to the DPF-equipped 758 variant and not directly interchangeable with non-DPF F9Q codes.
The F9Q 758's primary reliability risk is DPF system faults, with elevated incidence in vehicles driven primarily on short urban trips. Renault internal service data indicated a high correlation between sensor failures and incomplete regeneration cycles, while owner data suggests EGR valve clogging remains common. Ensuring regular highway driving and using low-ash oil are critical preventative measures.
Analysis derived from Renault technical bulletins (2006-2010) and UK DVSA failure statistics (2012-2022). Repair procedures should follow manufacturer guidelines.
