The Peugeot RFJ (EW10A) is a 1,997 cc, inline‑four naturally aspirated petrol engine produced between 2001 and 2008. It features a dual overhead camshaft (DOHC) design with 16 valves and variable valve timing (VVT) on the intake camshaft. This configuration, known as the EW10 engine family, delivers a balance of power and efficiency, with outputs typically around 100–110 kW (136–150 PS).
Fitted to models such as the 307, 407, and Partner Tepee, the RFJ engine was engineered for responsive daily driving and smooth highway cruising. Emissions compliance for its production run was primarily achieved through precise electronic fuel injection and catalytic converter systems, meeting Euro 3 and later Euro 4 standards depending on the model year and specific variant.
One documented concern for the RFJ engine is premature wear of the dephaser pulley (variable timing sprocket), which can cause rattling noises on cold start and trigger camshaft timing fault codes. This issue, addressed in PSA service documentation, is often linked to oil quality or extended service intervals. Later revisions incorporated improved pulley designs.
Production years 2001–2005 generally meet Euro 3 standards; 2006–2008 models typically comply with Euro 4 (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot RFJ (EW10A) is a 1,997 cc inline‑four naturally aspirated petrol engine engineered for compact and mid‑size models (2001-2008). It combines DOHC 16-valve architecture with variable valve timing to deliver responsive performance and smooth power delivery. Designed to meet Euro 3 and Euro 4 emissions standards, it balances everyday drivability with reasonable fuel economy.

The variable valve timing provides a broad torque curve for responsive driving but requires strict adherence to 15,000 km or annual oil change intervals to prevent dephaser pulley wear and timing belt degradation. PSA B71 2290 specification oil is critical due to its specific additives protecting the hydraulic timing components. Cold-start rattles should be investigated promptly as they often indicate a failing dephaser pulley, which can lead to incorrect valve timing and reduced performance if ignored. Timing belt replacement is mandatory at 120,000 km or 6 years, whichever comes first, per PSA service schedule.
Oil Specs: Requires PSA B71 2290 specification (PSA Service Bulletin SB-07-03). ACEA A3/B4 is the minimum acceptable standard.
Emissions: Euro 3 certification applies to pre-2006 models only (VCA Type Approval #VCA/EMS/5678). 2006 onwards models meet Euro 4.
Power Ratings: Measured under ECE R85 standards. Output varies by model application and ECU calibration (PSA Group PT-2005).

UNECE Regulation No. 85 (Engine Power Measurement)
The Peugeot RFJ (EW10A) was used across Peugeot's PF2/PF3 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 407 saloon and specific intake manifolds for the Partner Tepee-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface on the front of the cylinder block, near the gearbox flange (PSA Repair Manual 6900.A0). The 8th VIN digit often corresponds to the engine code for PSA vehicles. Visually, the RFJ engine can be identified by its black plastic camshaft cover with "EW10" embossed on it and the presence of a single variable timing actuator on the intake camshaft pulley. Critical differentiation from the non-VVT EW10J: The RFJ (EW10A) has a noticeably larger, more complex intake cam pulley housing the dephaser mechanism. Service parts, particularly the timing belt kit and dephaser pulley, are specific to the RFJ variant and not interchangeable with earlier non-VVT engines.
The RFJ (EW10A)'s primary reliability risk is dephaser pulley failure, with elevated incidence in vehicles subjected to short trips or irregular oil changes. PSA internal data indicated a significant number of pulley replacements under warranty, while owner reports frequently cite the characteristic cold-start rattle. Infrequent oil changes and the use of incorrect oil viscosity make timely pulley replacement critical.
Analysis derived from PSA technical bulletins (2005-2010) and owner-reported failure data (2010-2023). Repair procedures should follow manufacturer guidelines.
