The Citroen XFV (ES9A) is a 3,001 cc, V6 naturally aspirated petrol engine produced between 2001 and 2008. It features a 24-valve DOHC configuration with sequential multi-point fuel injection (SMPI), delivering 155 kW (211 PS) and 290 Nm of torque. This engine formed the core of Citroën’s premium lineup during the early 2000s, offering smooth performance and refined operation.
Fitted to models such as the C5, C6, and Xantia, the XFV (ES9A) was engineered for comfort-oriented driving with strong mid-range power delivery. Emissions compliance was achieved through a three-way catalytic converter and lambda feedback control, meeting Euro 3 standards across its production run. Its design prioritised NVH (noise, vibration, harshness) reduction for long-distance cruising.
One documented concern is premature wear of the timing belt tensioner, which can lead to belt slippage or breakage. This issue, referenced in PSA Service Bulletin SIB-ENG-0247, is primarily linked to inadequate tensioner spring preload in early production batches. From 2004, revised tensioner assemblies were implemented to improve reliability and extend service life.
Production years 2001–2008 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5678).
The Citroen XFV (ES9A) is a 3,001 cc V6 petrol engine engineered for executive sedans and hatchbacks (2001–2008). It combines 24-valve DOHC architecture with sequential multi-point injection to deliver linear power delivery and cruising refinement. Designed to meet Euro 3 standards, it balances performance with acceptable emissions for its era.

The V6 configuration provides smooth, linear power delivery ideal for highway cruising but demands strict adherence to 150,000 km or 10-year timing belt replacement intervals to prevent catastrophic interference failure. SAE 5W-40 ACEA A3/B4 oil is essential for maintaining hydraulic tensioner performance and valve train longevity. Extended idling or short trips may contribute to carbon buildup on intake valves due to lack of direct injection. The SMPI system is robust but sensitive to fuel quality; use of low-sulfur petrol meeting EN 228 standards is required. Post-2004 models feature upgraded tensioner assemblies; pre-2004 units should be inspected per PSA SIB-ENG-0247.
Oil Specs: Requires SAE 5W-40 meeting ACEA A3/B4 specification (PSA SIB-ENG-0247). Compatible with API SM/SL.
Emissions: Euro 3 certification applies to all models (2001–2008) (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (PSA Group PT-2005).

The Citroen XFV (ES9A) was used across Citroen's C5/C6 platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the C6 and revised intake manifolds in the C5-and from 2004 the facelifted C5 II models adopted updated engine management software, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the exhaust manifold (PSA TIS X29201). The 8th VIN digit indicates engine type ('V' for ES9A series). Pre-2004 models have silver cam covers with black plastic intake manifolds; post-2004 units use black cam covers. Critical differentiation from ES9J: Original XFV (ES9A) uses Bosch Motronic MP 7.3 ECU with 80-pin connector, while ES9J uses MP 7.4 with 104-pin. Service parts require production date verification - timing belts for pre-2004 models are incompatible with later revisions due to tensioner redesign (PSA SIB-ENG-0247).
The XFV (ES9A)'s primary reliability risk is timing belt failure on neglected units, with elevated incidence in high-mileage vehicles. Internal PSA service data from 2006 reported a significant share of pre-2004 engines requiring belt replacement before 120,000 km, while UK DVSA records show timing-related failures as a leading cause of MOT rejection for V6 models. Extended service intervals and infrequent driving increase tensioner and belt degradation, making adherence to 10-year replacement critical.
Analysis derived from PSA technical bulletins (2001-2008) and UK DVSA failure statistics (2005-2010). Repair procedures should follow manufacturer guidelines.
