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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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.
