The Renault F9Q 812 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2012 and 2018. It features an evolution of the common rail direct injection system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form, it delivers 96 kW (130 PS) and 320 Nm of torque, offering enhanced low — end responsiveness for urban and highway driving.
Fitted to models such as the Mégane III facelift, Scénic III, and later Captur units, the F9Q…
Production years 2012–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/8766).
The Renault F9Q 812 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size models (2012-2018). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver strong low‑rpm torque and efficient cruising. Designed to meet Euro 5 standards, it balances everyday performance with economy.

The Renault F9Q 812 was used across Renault's C/D platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Laguna and revised exhaust routing in the Scénic-but no major facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The F9Q 812's primary reliability risk is EGR valve and cooler clogging, with elevated incidence in vehicles subjected to frequent short trips. Renault internal service data indicates EGR-related faults as a leading cause of workshop visits for this engine, while UK DVSA MOT statistics consistently show DPF warnings as a common failure point. Neglecting oil changes and using incorrect oil specifications accelerate turbo wear and chain tensioner issues, making maintenance discipline critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F9Q 812 is generally more reliable than its predecessor (F9Q 744), particularly regarding the fuel pump. Its main vulnerabilities are the EGR system and DPF, which require proactive maintenance. With regular oil changes using RN0700/0710 spec oil and sufficient highway driving, it can be a durable and economical engine.
The most frequent issues are EGR valve and cooler clogging, DPF regeneration failures (often due to driving style), and turbo actuator faults. Oil leaks from the rocker cover gasket are also common as the engine ages. These are covered in Renault service documentation and are common to many Euro 5 diesels.
The F9Q 812 1.9 dCi 130 engine was primarily used in the facelifted Renault Mégane III (2012-2016), Scénic III (2012-2016), and the first-generation Captur (2013-2018, in some markets). It was also found in limited quantities in the Nissan Qashqai J11 (2014-2017) for specific European markets.
Yes, the F9Q 812 responds well to ECU remapping. A Stage 1 tune can safely increase power to around 150-160 PS and torque to 350-370 Nm. The stock turbo and internals are generally capable of handling this. More aggressive tuning may require an upgraded intercooler and clutch.
Official combined figures are around 5.3 L/100km (53 mpg UK). Real-world consumption typically ranges from 5.8-6.8 L/100km (42-49 mpg UK) in mixed driving, depending on the vehicle and driving style. Highway cruising can yield under 5.0 L/100km (56 mpg UK).
Yes. The F9Q 812 is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is very durable with proper maintenance.
Renault specifies a 5W-30 synthetic oil meeting the RN0700 or RN0710 standard. This is crucial for protecting the turbocharger, high-pressure fuel system, and emissions components. Using the correct oil and adhering to 15,000 km (or annual) change intervals is vital for engine health.
