The Peugeot T8A (DJ5T) is a 1,587 cc, inline‑four naturally aspirated petrol engine produced between 2004 and 2010. It features double overhead camshafts (DOHC), 16 valves, and sequential multi‑point fuel injection. In standard specification, it delivered 80 kW (109 PS) and 145 Nm of torque, offering a balance of economy and adequate performance for city and highway use.
Fitted primarily to the 206 and 207 models, the T8A engine was engineered for compact car applicatio…
Production years 2004–2010 meet Euro 4 standards .
The Peugeot T8A (DJ5T) is a 1,587 cc inline‑four naturally aspirated petrol engine engineered for supermini and compact hatchbacks (2004-2010). It combines DOHC 16-valve architecture with sequential multi-point injection to deliver smooth, predictable power for urban environments. Designed to meet Euro 4 standards, it emphasizes fuel economy and low emissions for its class.

The Peugeot T8A (DJ5T) was used across Peugeot's PF1 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 207 and revised intake manifolds for the 206 CC. 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 T8A's primary reliability risk is timing belt tensioner failure, with elevated incidence in high-mileage units. Peugeot service bulletins document this issue, while general owner reports highlight ignition coil failures as a common secondary concern. Adherence to correct service intervals and using quality parts is critical for mitigating these risks.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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
The T8A engine is generally reliable if its critical timing belt and tensioner are replaced at or before the 80,000 km interval. Ignition coils are a common wear item but are inexpensive and easy to replace. With proper maintenance, particularly timely timing belt changes, these engines can easily exceed 200,000 km.
The most critical issue is failure of the timing belt tensioner pulley, which can lead to catastrophic engine damage. Other common problems include ignition coil pack failures, oil leaks from the front crankshaft seal, and coolant leaks from the thermostat housing gasket. These are well-documented in Peugeot service information.
This 1.6L petrol engine was used in the Peugeot 206 (2004-2008) and the Peugeot 207 (2006-2010). It was a common engine option for these popular supermini models during the Euro 4 era.
Modest gains are possible. An ECU remap can yield around 5-8 kW (7-10 PS). More significant power increases require hardware changes like a performance exhaust and intake, which offer limited returns on a naturally aspirated engine. Reliability should be the priority, especially given the engine's interference design.
Real-world fuel economy is very good. In a Peugeot 207, expect around 6.5-7.5 L/100km (38-43 mpg UK) in mixed driving. Highway cruising can see figures closer to 5.0-5.5 L/100km (51-56 mpg UK). City driving will be higher, around 8.0-9.0 L/100km (31-35 mpg UK).
Yes. The T8A is an interference engine. If the timing belt were to fail or jump teeth, the pistons would collide with the open valves, causing severe internal engine damage. This makes adhering to the 80,000 km replacement interval absolutely critical.
Peugeot specifies an oil meeting ACEA A3/B4 standards. A 5W-30 or 10W-40 viscosity grade is typically recommended. Using the correct specification helps protect the engine's internals and ensures proper lubrication under various operating conditions.
