The Renault F9Q 782 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2012 and 2018. It features a cast iron block, aluminium cylinder head, double overhead camshafts (DOHC), and a variable geometry turbocharger (VGT). This engine, co — developed with Nissan, delivers robust low — end torque for confident overtaking and towing, with outputs ranging from 96 kW (130 PS) to 110 kW (150 PS).
Fitted to models like the Mégane III, Scénic III, and Koleos, the F9Q 782 w…
All production years (2012–2018) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Renault F9Q 782 is a 1,870 cc inline‑four turbo‑diesel engineered for compact and mid‑size SUVs and hatchbacks (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 782 was used across Renault's Mégane III/Scénic III platforms with transverse mounting and licensed to Nissan for use in the Qashqai and X-Trail. This engine received platform-specific adaptations-reinforced engine mounts in the Koleos and specific ECU mapping in the Scénic-and from 2012 received updates for Euro 5 compliance, including revised injectors and ECU software. Partnerships allowed Nissan to use this engine as the M9R. All adaptations are documented in OEM technical bulletins.
The F9Q 782's primary reliability risk is dual-mass flywheel (DMF) failure, though incidence is lower than in the earlier F9Q 752. Renault internal service data indicated a reduced rate of DMF replacement compared to pre-2012 engines, while UK DVSA records show EGR-related faults as a common MOT failure point. High-torque loads and aggressive driving can still accelerate DMF wear, making gentle take-offs and correct maintenance critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The F9Q 782 is generally robust with strong torque. It features the revised, more durable dual-mass flywheel (DMF) introduced around 2012, making it more reliable than the earlier F9Q 752. With strict adherence to service intervals and using the correct RN0710 oil, a well-maintained F9Q 782 can be very reliable long-term.
The most frequent issues are dual-mass flywheel (DMF) failure (though less common than in F9Q 752), EGR valve/cooler clogging, turbo actuator faults, and injector seal leaks. These are well-documented in Renault service bulletins. Regular maintenance, including EGR cleaning and timely oil changes, can mitigate many of these problems.
The F9Q 782 was used in the later phase of the Renault Mégane III (2012-2016), Scénic III (2012-2016), and first-generation Koleos (2012-2016), typically as the dCi 130 or dCi 150. It was also used by Nissan in the Qashqai (J11) and X-Trail (T32) as the 1.6 dCi engine.
Yes, the F9Q 782 responds well to ECU remapping. Stage 1 tunes can safely increase power to around 170-180 PS and torque to 380-400 Nm. The stock internals are strong, but pushing beyond this may require upgraded components like a clutch, intercooler, or turbo actuator to handle the extra stress.
Fuel economy is good. In a Mégane III dCi 130, expect around 5.5 L/100km (51 mpg UK) combined. The dCi 150 in a heavier Koleos might return 6.2 L/100km (45 mpg UK). Real-world figures vary with driving style, but 45-55 mpg UK is typical for mixed driving in a healthy F9Q 782.
Yes. The F9Q 782 is an interference engine. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic engine damage. Fortunately, the timing chain is generally very durable if oil changes are not neglected.
Renault mandates a 5W-30 synthetic oil meeting the RN0710 specification. This is critical for protecting the turbocharger, timing chain, and emissions systems. Using the correct oil and changing it every 20,000 km (or annually) is essential for long-term engine health.
