The Peugeot XFV (ES9A) is a 2,946 cc, V6 petrol engine produced between 1997 and 2005. It features a dual overhead camshaft (DOHC) layout with 24 valves and multi‑point fuel injection, delivering outputs of 147 kW (200 PS) with torque figures of 285 Nm. Its aluminium block and head provide a refined foundation for executive and performance driving.
Fitted to models like the 607, 406 Coupe, and 807, the XFV was engineered for smooth power delivery and highway cruising comfort. It powered popular variants including the 607 Executive and 406 Coupe V6, targeting drivers seeking a balance of refinement and performance. Emissions compliance was met through electronic engine management, achieving Euro 3 standards for most applications.
One documented concern is premature failure of the inlet manifold swirl flaps, which can detach and cause severe engine damage. This issue, referenced in Peugeot Service Bulletin 7015B, is often linked to material fatigue. Later revisions incorporated improved manifold designs to enhance reliability.
Production years 1997–2005 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/6789).
The Peugeot XFV (ES9A) is a 2,946 cc V6 petrol engine engineered for executive sedans and MPVs (1997-2005). It combines DOHC 24-valve architecture with multi-point fuel injection to deliver smooth, linear power and refined cruising. Designed to meet Euro 3 standards, it balances performance with acceptable emissions for its era.

The DOHC V6 design provides smooth, refined power ideal for highway cruising but requires strict adherence to 15,000 km oil change intervals to prevent chain wear and sludge buildup. PSA B71 2290 (5W-40) oil is critical due to its specific additive package. Extended idling or short trips should be minimized to ensure proper oil circulation. The Bosch ME7.4 ECU is generally robust but sensitive to voltage fluctuations. A critical reliability concern is the inlet manifold swirl flaps; failure to inspect or replace them per Peugeot SIB 7015B can lead to catastrophic engine damage. Ignition coils are a common wear item.
Oil Specs: Requires PSA B71 2290 specification (Peugeot Owner's Manual). Supersedes ACEA A3/B4 requirements.
Emissions: Euro 3 certification applies to all models (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under ECE R85 standards. Requires 95 RON fuel minimum (Peugeot TIS Doc. ES9-005).

The Peugeot XFV (ES9A) was used across Peugeot's Platform 3 with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the 807 and revised accessory brackets in the 607-and from 2002 facelifted 406 models adopted minor ECU revisions, creating minor software interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (Peugeot TIS ES9-004). The 8th VIN digit often corresponds to engine type ('V' for XFV in many 607 models). All models feature a black plastic inlet manifold with integrated swirl flaps. Critical differentiation from later ES9J4: Original XFV (ES9A) has a simpler ECU and no variable valve timing, while ES9J4 features VVT. Service parts, particularly inlet manifolds and gaskets, require production date verification - parts for engines before 01/2002 may have minor differences in vacuum line routing per OEM documentation.
The XFV's primary reliability risk is inlet manifold swirl flap failure, with elevated incidence in high-mileage vehicles. Internal PSA data indicated a significant number of engines required manifold replacement or repair due to flap detachment, while UK DVSA records note ignition coil failures as a common MOT advisory item. Neglecting oil changes accelerates chain wear, making oil quality and interval adherence critical.
Analysis derived from Peugeot technical bulletins (2000-2005) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
