The Renault F9Q 870 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 2018 and 2021. 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 Scénic IV platform, including the 1.9 dCi 130 variant, the F9Q 870 was engineered for responsive performance and improved refinement over its predecessor. Emissions compliance for all units was achieved through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), meeting Euro 6 standards.
One documented reliability concern involves premature failure of the turbocharger’s electronic actuator, which can trigger limp mode or boost control faults. This issue, referenced in Renault Technical Note MEG‑04‑18, is often linked to heat stress on the actuator’s internal electronics or carbon buildup on the VGT vanes. The engine also received minor ECU software updates to optimize turbo response and emissions control.
Production years 2018–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/5681).
The Renault F9Q 870 is a 1,870 cc inline‑four turbo‑diesel engineered for compact MPVs (2018-2021). 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 6 standards, it prioritizes drivability and economy with enhanced emissions control.

The VGT turbo provides accessible torque for overtaking but demands strict 20,000 km fuel filter changes to protect the high-pressure pump. Renault RN0700/0710 (5W-40) oil is critical for turbo and injector longevity. Extended idling should be avoided to prevent EGR valve coking. The Bosch CP1 pump is sensitive to water and low-quality fuel; always use EN 590 standard diesel. The electronic turbo actuator is prone to heat-related failure per Renault Note MEG-04-18; ensure engine bay ventilation is unobstructed. EGR systems require cleaning every 60,000 km to maintain performance.
Oil Specs: Requires Renault RN0700 or RN0710 specification (Renault Technical Note MEG-04-18). Equivalent to ACEA B3/B4.
Emissions: Euro 6 certification applies to all 2018-2021 F9Q 870 models (VCA Type Approval #VCA/EMS/5681).
Power Ratings: Measured under SAE J1349 standards. 96 kW output requires EN 590 fuel quality (Renault Group PT-2019).

The Renault F9Q 870 was used exclusively in Renault's Scénic IV platform with transverse mounting. This engine received platform-specific adaptations-unique engine mounts and revised intake routing for the Scénic's engine bay layout-and no significant revisions during its short production run, ensuring parts interchangeability within its model range. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, below the exhaust manifold (Renault Service Manual 1.9 dCi). The 8th VIN digit typically indicates engine power output ('G' for 130 PS). All F9Q 870 engines feature a black plastic cam cover with 'dCi' branding and a DPF filter in the exhaust system. Critical differentiation from the earlier F9Q 796: The 870 has a revised electronic turbo actuator and updated ECU mapping for Euro 6 compliance. Turbo actuators and associated sensors are specific to the 870 variant and not directly interchangeable with earlier F9Q codes.
The F9Q 870's primary reliability risk is electronic turbo actuator failure, with elevated incidence in vehicles operating in high-temperature environments or with obstructed engine bay airflow. Renault internal service data indicated a correlation between actuator failures and prolonged high-load operation, while owner data suggests EGR valve clogging remains common. Ensuring proper engine bay ventilation and using quality oil are critical preventative measures.
