The Peugeot NFR (TU5JP4B) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 2004 and 2012. It features a dual overhead camshaft (DOHC) 16‑valve design with multipoint fuel injection and variable valve timing (VVT), delivering 80 kW (109 PS) and 142 Nm of torque. Its aluminum alloy construction and VVT system enabled a balance of efficiency and responsive performance for compact applications.

The Peugeot NFR (TU5JP4B) was used across Peugeot's 20x/30x platform with transverse mounting. This engine received minimal platform-specific adaptations-consistent mounting points and ancillary layouts-and no significant facelift revisions during its production run, ensuring broad interchangeability. 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.
The NFR's primary reliability risk is plastic intake manifold cracking, with elevated incidence in high-mileage or hot-climate examples. Peugeot Technical Note 05C documents this as a common service item, while owner surveys indicate it as a frequent cause of drivability complaints. Extended high-RPM operation increases thermal stress, making preventative manifold inspection critical.
Analysis derived from Peugeot technical bulletins (2004-2012) and owner club failure statistics (2010-2023). 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
Generally, yes. The NFR is a robust and well-proven engine. With proper maintenance, particularly timely timing belt changes and addressing the common intake manifold issue, these engines can easily surpass 250,000 km. The addition of VVT adds complexity but is generally reliable if oil changes are not neglected.
The most frequent issues are cracking of the plastic intake manifold, failure of the VVT solenoid causing power loss, failure of individual ignition coil packs causing misfires, and faulty coolant temperature sensors leading to poor running. These are well-documented in Peugeot service notes.
The NFR engine was primarily fitted to the Peugeot 207 hatchback (2006-2012, XS and Sport trims) and the Peugeot 307 hatchback and SW (2004-2008, SE and Sport trims). It was an evolution of the earlier EP3 engine, adding variable valve timing for improved efficiency and torque.
Yes, modest gains are possible. Common modifications include installing a performance air filter, a free-flow exhaust system, and having the ECU remapped. These can yield 10-15% more power. The VVT system responds well to tuning, making it a popular choice for enthusiasts.
Very good for a naturally aspirated petrol engine. Expect real-world figures of approximately 7.2 L/100km (39 mpg UK) in mixed driving for a 207. Highway cruising can see consumption drop to around 5.6 L/100km (50 mpg UK). The 307 will be slightly less efficient due to its larger size and weight.
Yes. The NFR is an interference engine. If the timing belt snaps or jumps teeth, the pistons will collide with the open valves, causing severe and expensive internal engine damage. Strict adherence to the 120,000 km / 6-year replacement interval is essential.
Peugeot specifies an oil meeting ACEA A3/B3 standards, typically a 10W-40 or 5W-40 semi-synthetic or synthetic blend. Using a quality petrol engine oil is crucial for protecting the internals, especially the VVT system. Avoid using oils designed only for diesel engines.
