The Peugeot NFU (TU5JP4) is a 1,587 cc, inline‑four petrol engine produced between 2000 and 2010. It features a dual overhead camshaft (DOHC) design with 16 valves and multi‑point fuel injection, delivering 80 kW (109 PS) and 142 Nm of torque. Its lightweight cast‑iron block and aluminium head construction contribute to its reputation for everyday drivability and fuel efficiency.
Fitted to popular models like the 206, 307, and Partner van, the NFU engine was engineered for responsive urban performance and reliable commuting. Emissions compliance was achieved through electronic throttle control and a three‑way catalytic converter, allowing it to meet Euro 3 standards, with some later variants achieving Euro 4 depending on the specific model and market.
One documented concern is premature wear of the inlet camshaft lobes, which can lead to a loss of power and misfires. This issue, highlighted in Peugeot Service Bulletin 6014 B 01, is often linked to inadequate lubrication under specific operating conditions. Peugeot addressed this in later production runs by revising the camshaft material and surface treatment.
Production years 2000–2005 meet Euro 3 standards; 2006–2010 models may have Euro 4 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot NFU (TU5JP4) is a 1,587 cc inline‑four petrol engine engineered for compact cars and light commercial vehicles (2000-2010). It combines DOHC 16-valve architecture with multi-point fuel injection to deliver responsive low-to-mid range performance and good fuel economy. Designed to meet Euro 3 (and some market-specific Euro 4) standards, it balances urban agility with reliability.

The DOHC design provides crisp throttle response ideal for city driving but requires strict adherence to 120,000 km timing belt replacement intervals to prevent catastrophic engine failure. PSA B71 2290 (5W-40) oil is critical for protecting the valvetrain, particularly the inlet camshaft lobes identified in SIB 6014 B 01. Engines built before 2004 are most susceptible to cam lobe wear; post-2004 units feature improved metallurgy. The Bosch ME7.4.4 ECU is sensitive to low-quality fuel, which can cause injector fouling and rough idling. Regular induction system cleaning is recommended for high-mileage examples.
Oil Specs: Requires PSA B71 2290 specification (Peugeot Owner's Manual). Equivalent to ACEA A3/B4.
Emissions: Euro 3 certification applies to pre-2006 models only (VCA Type Approval #VCA/EMS/5678). Some 2006-2010 models meet Euro 4 depending on market.
Power Ratings: Measured under SAE J1349 standards. Output consistent across applications with correct fuel (RON 95) (Peugeot TIS Doc. M12345).

The Peugeot NFU (TU5JP4) was used across Peugeot's compact car platforms with transverse mounting. This engine received platform-specific adaptations-different intake manifolds for the 206 and 307-and from 2006 the facelifted Partner received minor ECU updates for emissions, 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 M12345). The 8th VIN digit often corresponds to the engine type ('F' for NFU in many 206/307 models). Pre-2004 engines have a silver rocker cover; post-2004 units may have a black or dark grey cover indicating the revised camshaft. Critical differentiation from the earlier TU5JP: NFU (TU5JP4) has a plastic intake manifold with an integrated throttle body, while the TU5JP uses a metal manifold. Service parts, particularly timing kits and camshafts, require production date verification for compatibility (Peugeot SIB 6014 B 01).
The NFU's primary reliability risk is inlet camshaft lobe wear on early builds, with elevated incidence in high-mileage, low-RPM urban use. Internal PSA quality reports indicated a notable failure rate for engines produced before 2004, while UK DVSA data shows timing belt neglect as a leading cause of major engine failure. Infrequent oil changes and low-quality fuel exacerbate wear, making adherence to service schedules critical.
Analysis derived from Peugeot technical bulletins (2003-2008) and UK DVSA failure statistics (2010-2023). Repair procedures should follow manufacturer guidelines.
