The Renault F9Q 796 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. 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 III and Scénic III platforms, including the 1.9 dCi 130 variant, the F9Q 796 was engine…
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5680).
The Renault F9Q 796 is a 1,870 cc inline‑four turbo‑diesel engineered for compact MPVs and hatchbacks (2010-2018). 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 5 standards, it prioritizes drivability and economy with enhanced emissions control.

The Renault F9Q 796 was used across Renault's Mégane III and Scénic III 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 796's primary reliability risk is EGR cooler failure, with elevated incidence in vehicles with high mileage or frequent short trips. Renault internal service data indicated a correlation between cooler failures and thermal cycling stress, while owner data suggests turbo actuator faults remain common. Ensuring coolant system integrity and using quality oil are critical preventative measures.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F9Q 796 can be reliable with proper maintenance, particularly regarding the EGR cooler and DPF system. Its main weakness is the EGR cooler, which can fail internally and contaminate the coolant. With regular highway driving, strict adherence to service schedules, and use of quality oil, these engines can exceed 200,000 km. The timing chain is generally robust.
The most frequent issues are EGR cooler failure, turbo actuator faults, DPF regeneration problems, and leaking injector seals. These are well-documented in Renault service bulletins. Neglecting long drives for DPF regeneration and ignoring early signs of coolant loss are primary causes of major failures.
The F9Q 796 1.9 dCi 130 engine was used in the Renault Mégane III (2010-2016) and Scénic III (2010-2018). It was specifically engineered to meet Euro 5 emissions standards and was not used in the Kadjar or other newer Renault platforms, which adopted different engine families.
Yes, the F9Q 796 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. A Mégane III 1.9 dCi 130 typically achieves 5.6 L/100km (city) and 4.1 L/100km (highway), or around 54 mpg UK combined. Real-world economy is heavily dependent on driving style and the frequency of DPF regenerations, which can temporarily increase consumption.
Yes. The F9Q 796 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 796, using a low-ash (Low SAPS) oil is vital to prevent DPF clogging. Change intervals should not exceed 20,000 km or 12 months.
