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…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The XFV is a smooth and powerful engine but has a critical weakness: the inlet manifold swirl flaps. If these fail, they can cause catastrophic engine damage. With the flaps removed or the manifold replaced preventatively, and with diligent maintenance (especially oil changes), it can be a very reliable engine for high mileage.
The most critical issue is inlet manifold swirl flap failure. Other common problems include ignition coil pack failures, oil leaks from the rocker cover gaskets, and timing chain wear/noise. These are well-documented in PSA service bulletins, with the swirl flap issue being the most severe.
This 3.0L V6 petrol engine was used in the Peugeot 607 (1999-2005), 406 Coupe (1997-2004), and 807 MPV (2002-2005). It also powered the Citroën C8 (2002-2005). It was found in variants like the 607 Executive and 406 Coupe V6, primarily meeting Euro 3 emissions standards.
Yes. ECU remaps can yield +10-20 kW by optimizing ignition and fuel maps. More significant power requires hardware like performance cams, exhaust, and intake. The engine responds well to tuning, and the bottom end is robust, making it a good candidate for moderate upgrades.
Moderate for its size and era. In a Peugeot 607 3.0 V6, expect ~11.5 L/100km (city) and ~7.5 L/100km (highway), or around 25 mpg UK combined. Real-world economy typically ranges from 22-28 mpg UK, depending heavily on driving style and vehicle condition.
Yes. The XFV is an interference engine. If the timing chain jumps or breaks, the pistons will collide with the open valves, causing catastrophic engine damage. This makes maintaining the timing chain in good condition absolutely essential.
Peugeot specifies a 5W-40 synthetic oil meeting the PSA B71 2290 standard. Using the correct oil is vital for protecting the engine and ensuring proper lubrication. Change intervals should not exceed 15,000 km or 12 months to maintain engine health and prevent sludge buildup.
