The Renault F8Q 682 is a 1,870 cc, inline‑four turbo‑diesel engine produced between 1999 and 2005. It features a SOHC 8‑valve design with indirect injection and a fixed‑geometry turbocharger, delivering outputs around 50 kW (68 PS) and 132 Nm of torque. Its simple, robust architecture prioritized low cost and ease of maintenance for entry-level commercial and fleet applications.
Fitted primarily to the Kangoo and Clio Symbol, the F8Q 682 was engineered for dependable, economical operation in urban delivery and light passenger roles. Emissions compliance for its era was managed through basic exhaust gas recirculation (EGR), meeting Euro 2 standards as verified under its type approval.
A documented service concern involves premature failure of the vacuum‑operated turbocharger wastegate actuator diaphragm, leading to boost control faults. This issue, referenced in Renault Technical Note MEC 0012, is often caused by heat ageing and vacuum line degradation. Later F8Q variants introduced electronic boost control to mitigate this.
Production years 1999–2005 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/5679).
The Renault F8Q 682 is a 1,870 cc inline‑four turbo‑diesel engineered for light commercial and compact vehicles (1999-2005). It combines indirect injection with a fixed‑geometry turbocharger to deliver predictable, low‑end pulling power and mechanical simplicity. Designed to meet Euro 2 standards, it prioritizes serviceability and cost‑effective operation.

The fixed-geometry turbo provides predictable, lag-free response ideal for load-carrying but requires vigilant inspection of vacuum hoses and the wastegate actuator to prevent boost faults. ACEA B3/B4 oil is critical for protecting the rotary injection pump and valve train. The SOHC chain is generally robust but should be inspected at major services. The VP37 pump demands clean, low-sulfur diesel to prevent internal wear. Pre-heating glow plugs for 5-10 seconds in cold weather is essential for reliable starting and reduced engine wear. No major OEM upgrades were issued for this specific variant.
Oil Specs: Requires ACEA B3/B4 specification (Renault Service Manual 6010A). Mineral or semi-synthetic 10W-40/15W-40 is typical.
Emissions: Euro 2 certification applies to all 1999–2005 F8Q 682 models (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under EEC 80/1269 standards (Renault PT‑1999). Output is consistent across applications.

The Renault F8Q 682 was used across Renault's light commercial and compact platforms with transverse mounting. This engine received platform-specific adaptations-minor ECU mapping for the Kangoo versus the Clio Symbol-creating no significant interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, adjacent to the fuel injection pump (Renault Service Manual 6010A). The 8th VIN digit often corresponds to the engine code (e.g., 'F' for F8Q series). Visually, the F8Q 682 is identified by its SOHC 8-valve head, Bosch VP37 injection pump mounted on the right side, and the Garrett T2 turbo with a prominent vacuum actuator on the wastegate. Differentiate from later F9Q engines by the absence of a variable geometry turbo (VGT) and common-rail injection. Service parts for the injection pump and turbo actuator are specific to the F8Q 682 build date.
The F8Q 682's primary reliability risk is vacuum system failure affecting turbo boost control, with elevated incidence in high-mileage or poorly maintained vehicles. Renault technical notes indicate this was a frequent workshop visit item, while its simple mechanical design otherwise offers good durability. Neglected vacuum lines and infrequent oil changes make proactive inspection critical.
