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 f…
Production years 2000–2005 meet Euro 3 standards; 2006–2010 models may have Euro 4 compliance depending on market .
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The NFU is generally robust, but early models (pre-2004) have a known issue with inlet camshaft wear. Engines from 2004 onwards feature a revised, more durable camshaft. With strict adherence to timing belt and oil change schedules, a well-maintained NFU engine can easily exceed 200,000 km.
The most critical issues are premature inlet camshaft lobe wear (pre-2004), timing belt failure if neglected, carbon buildup on the throttle body, and coolant leaks from aging plastic components. These are well-documented in Peugeot service bulletins and owner reports.
This 1.6L petrol engine was widely used in the Peugeot 206 (Phase 2, 2000-2006), 307 (2001-2008), and Partner van (2002-2010). It was also shared with Citroën, appearing in the C3 (2002-2009) and C2 (2003-2009) models.
Yes, moderately. The NFU responds well to ECU remapping, typically gaining 10-15 kW (15-20 PS) and improved torque. Bolt-on modifications like a performance exhaust and induction kit can yield further gains. The bottom end is strong, but pushing power significantly higher requires internal upgrades.
Fuel economy is good for its era. In a Peugeot 206, expect around 7.5 L/100km (38 mpg UK) in combined driving. In the heavier 307, figures are closer to 8.0-8.5 L/100km (33-35 mpg UK). Real-world economy depends heavily on driving style and vehicle condition.
Yes. The NFU is an interference engine. If the timing belt fails or jumps teeth, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This makes the 120,000 km timing belt replacement interval absolutely critical.
Peugeot specifies oil meeting the PSA B71 2290 standard, typically a 5W-40 or 10W-40 fully synthetic oil. Using the correct specification is vital for protecting the camshafts and ensuring proper lubrication throughout the engine's operating range.
