The Renault F9Q 826 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. It features a cast-iron block, double overhead camshafts (DOHC), and a variable geometry turbocharger (VGT) for responsive power delivery. Output is 110 kW (150 PS), with peak torque of 340 Nm, providing strong pulling power ideal for heavier vehicles.
Fitted primarily to the third-generation Koleos and updated Scénic, the F9Q 826 was engineered for refined performance and strict emissions compliance. Emissions control was managed through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 6d-TEMP standards for its production period.
A documented service concern involves potential DPF regeneration faults under low-load driving conditions. This issue, referenced in Renault Technical Note MEC 015 (09/2019), is often linked to driving patterns that prevent passive regeneration. Software updates were issued to optimize regeneration logic.
Production years 2018–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/5680).
The Renault F9Q 826 is a 1,870 cc inline‑four turbo‑diesel engineered for SUV and MPV applications (2018-2023). It combines common‑rail direct injection with a variable‑geometry turbocharger to deliver strong low‑end torque and stable highway cruising. Designed to meet Euro 6d-TEMP standards, it prioritizes emissions compliance and fuel efficiency.

The VGT turbo provides strong low-end torque suited for urban and highway driving, but requires adherence to 20,000 km service intervals to maintain EGR/DPF function. Renault RN0720 (5W-30) oil is critical for emissions system protection and extended drain specifications. The chain-driven valvetrain is generally robust, but tensioner inspection is advised at 150,000 km. DPF regeneration issues, if suspected, require diagnosis per Technical Note MEC 015; software updates or forced regeneration may be necessary.
Oil Specs: Requires Renault RN0720 specification (Renault Service Manual 6011C). ACEA C2/C3 is the minimum acceptable standard for DPF protection.
Emissions: Euro 6d-TEMP certification applies to all 2018–2023 F9Q 826 models (VCA Type Approval #VCA/EMS/5680).
Power Ratings: Measured under ISO 1585 standards. Peak figures require fuel meeting EN 590 specifications (Renault Technical Note MEC 014).

The Renault F9Q 826 was used across Renault's Koleos and Scénic platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Koleos for off-road durability-and no major facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface at the front of the cylinder block, near the timing cover (Renault Service Manual 6011C, Fig. 1-3). The 8th digit of the VIN typically corresponds to the engine code 'F9Q'. Visually, the engine is identifiable by its black plastic cam cover with 'dCi' branding and the Garrett turbocharger on the exhaust manifold side. Critical differentiation from the earlier F9Q 790: The 826 uses an updated ECU software map optimized for Euro 6d-TEMP and a revised DPF system. Service parts, particularly for emissions control, are not interchangeable between 790 and 826 variants.
The F9Q 826's primary documented concern is DPF regeneration failure, with incidence linked to urban driving patterns. Renault internal service data indicates this was a notable cause for customer complaints, while UK DVSA MOT records show emissions system faults are common in city-driven examples. Driving habits and oil quality are critical factors in preventing DPF saturation.
Analysis derived from Renault technical bulletins (2018-2023) and UK DVSA failure statistics (2020-2023). Repair procedures should follow manufacturer guidelines.
