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 F…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The F9Q 758 can be reliable with proper maintenance, particularly regarding the DPF system. Its main weakness is the DPF pressure sensor and potential for DPF clogging on short trips. With regular highway driving, strict adherence to service schedules, and use of quality low-ash oil, these engines can exceed 250,000 km. The timing chain is generally robust.
The most frequent issues are DPF pressure sensor failure, EGR valve/carbon buildup, turbo actuator faults, and leaking injector seals. These are well-documented in Renault service bulletins. Neglecting long drives for DPF regeneration is the primary cause of DPF-related problems.
The F9Q 758 1.9 dCi 130 engine was used in the facelifted Renault Mégane II (2006-2008) and Scénic II (2006-2009). It was specifically introduced to meet Euro 4 emissions standards with a DPF and was not used in pre-facelift models or other Renault platforms like the Laguna.
Yes, the F9Q 758 responds well to ECU remapping. Stage 1 tunes can safely increase power to 150-160 PS and torque to 350 Nm. Supporting modifications like a DPF delete (where legally permissible) or larger intercooler are recommended for higher stages. Always ensure the fuel and emissions systems are in perfect condition before tuning.
Excellent for its time, though slightly less than the non-DPF 733 due to regeneration cycles. A Mégane II 1.9 dCi 130 typically achieves 5.8 L/100km (city) and 4.2 L/100km (highway), or around 52 mpg UK combined. Real-world economy heavily depends on driving style and DPF regeneration frequency.
Yes. The F9Q 758 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. For DPF-equipped engines like the 758, using a low-ash (Low SAPS) oil is vital to prevent DPF clogging. Change intervals should not exceed 20,000 km or 12 months.
