The IVECO Tector 4 – Diesel is a 3,920 cc, inline‑four turbo‑diesel engine produced between 2007 and 2011. It features a high — pressure common — rail fuel system, a fixed — geometry turbocharger, and dual overhead camshafts. In standard configurations, it delivered outputs ranging from 103 kW (140 PS) to 125 kW (170 PS), with peak torque figures between 450–500 Nm.
Fitted primarily to the IVECO Daily van and light truck variants, the Tector 4 was engineered for urban deliver…
Production years 2007–2011 meet Euro IV standards (EU Regulation (EC) No 715/2007).
The IVECO Tector 4 – Diesel is a 3,920 cc inline‑four turbo‑diesel engineered for light commercial vehicles (2007-2011). It combines common‑rail direct injection with a single fixed‑geometry turbocharger to deliver responsive low-end torque for stop-start driving. Designed to meet Euro IV standards, it prioritizes operational economy with regulatory compliance.

The IVECO Tector 4 – Diesel was used across IVECO's light commercial platforms with longitudinal mounting. This engine received platform-specific adaptations-optimized cooling for the Daily Van and reinforced mounts for the Daily Chassis Cab-creating minor service part variations. 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 Tector 4 – Diesel's primary reliability focus is EGR system maintenance, with elevated incidence in urban/stop-start duty cycles. IVECO service data indicates a correlation between extended low-load operation and EGR valve sticking, while adherence to oil change intervals is critical for long-term engine health. High soot loads from poor fuel or extended intervals make using the correct oil specification critical.
Analysis derived from IVECO technical bulletins (2007-2011) and EU regulatory maintenance guidelines. 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 Tector 4 is generally considered a robust and reliable engine for light commercial use. Its chain-driven timing and fixed-geometry turbo are less complex than some alternatives. Long-term reliability is heavily dependent on strict adherence to maintenance, especially oil changes and EGR system care. With proper servicing using correct fluids, these engines can achieve high mileages.
The most frequently documented issues involve the EGR system (valve sticking), turbocharger oil seals, and injector nozzle coking. Oil dilution from extended intervals or specific operating conditions is also a known concern if maintenance is neglected.
The Tector 4 – Diesel was the primary powerplant for the IVECO Daily range during its production, including the Daily Van (35S), Daily Minibus (35C), and Daily Chassis Cab (35D) variants, typically in the 3.5-tonne GVW class.
Yes, ECU remapping is possible and can yield modest power and torque increases. However, pushing beyond factory limits increases stress on the turbo, fuel system, and drivetrain. Any tuning should be performed by a specialist and accompanied by supporting modifications and more frequent maintenance.
Fuel economy varies greatly by vehicle weight, body type, and driving cycle. In a standard Daily Van on mixed urban/rural routes, expect figures around 10-12 L/100km. Heavier or more aerodynamically compromised bodies will see higher consumption.
Yes. The IVECO Tector 4 is an interference engine. If the timing chain were to fail or jump, valve and piston collision would likely occur, resulting in significant internal engine damage. Regular oil changes are critical to prevent chain wear.
IVECO specifies a 10W-40 heavy-duty diesel engine oil meeting ACEA E7 (or the manufacturer's equivalent IVECO specification). Using the correct oil is vital for controlling soot, protecting against wear, and ensuring the longevity of the engine and emissions systems.
