The Renault F9Q 818 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2007 and 2011. It features a cast iron block, aluminium cylinder head, common rail direct injection, and a variable geometry turbocharger (VGT). In standard European specification, it produced 96 kW (130 PS) and 300 Nm of torque, offering a balance of performance and fuel economy for its class.

Production years 2007–2011 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault F9Q 818 is a 1,870 cc inline‑four turbo‑diesel engineered for compact MPVs and hatchbacks (2007-2011). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong mid-range torque and efficient highway cruising. Designed to meet Euro 4 standards, it balances everyday drivability with fuel economy.

The Renault F9Q 818 was used across Renault's Mégane III and Scénic III platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping variations for different body styles-and no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
The F9Q 818's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. Renault service data indicates a notable number of pump replacements under warranty, while owner reports frequently cite stalling and hard starting as precursors. Fuel contamination and infrequent filter changes make adherence to fuel quality and maintenance schedules critical.
Analysis derived from Renault technical bulletins (2008-2012) and owner-reported failure data (2010-2023). 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 818 offers good performance but has a known weakness in its high-pressure fuel pump, particularly in early models or with poor fuel quality. With strict adherence to maintenance, using high-quality diesel and OEM filters, and addressing EGR issues promptly, it can be a dependable engine. Later examples or those with a replaced pump tend to be more robust.
The most frequent issues are high-pressure fuel pump failure, EGR valve and cooler clogging leading to performance loss, and turbocharger actuator faults causing boost problems. Glow plug failures are also common as the engine ages. These are well-documented in Renault service information and owner communities.
The F9Q 818 1.9 dCi 130 engine was primarily used in the Renault Mégane III (2008-2011) and Scénic III (2009-2011). It was the higher-output variant of the 1.9 dCi family for these models during that specific production period.
Yes, the F9Q 818 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 150-160 PS and torque to 350 Nm, leveraging the robust stock turbo and internals. More aggressive tuning requires upgraded components. Always ensure the fuel system is in perfect condition before tuning.
Official combined figures for the Mégane III 1.9 dCi 130 are around 5.3 L/100km (53 mpg UK). Real-world consumption typically ranges from 5.8-6.5 L/100km (43-48 mpg UK) in mixed driving, depending heavily on driving style and DPF regeneration cycles.
Yes. The F9Q 818 is an interference engine. If the timing chain were to fail or jump, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the timing chain is generally very durable with proper oil changes.
Renault mandates the use of RN0700 specification oil, typically a 5W-30 synthetic grade meeting ACEA C3 standards. Using the correct low-ash oil is crucial for protecting the DPF and ensuring the longevity of the turbocharger and timing chain.
