The Peugeot HNZ (EB2DT) is a 1,499 cc inline‑three turbocharged diesel engineered for compact hatchbacks and crossovers (2021-Present). It combines a high-pressure common rail injection system with a variable geometry turbocharger to deliver strong low‑rpm torque and class-leading fuel efficiency. Designed to meet Euro 6d emissions standards, it prioritises environmental compliance without sacrificing drivability.

The Peugeot HNZ (EB2DT) was introduced for Peugeot's latest compact 208 and 2008 platforms with transverse mounting. This engine received minor ECU updates for emissions fine-tuning, though core mechanical components remained fully interchangeable. 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 HNZ (EB2DT)'s primary reliability risk is EGR cooler clogging, with elevated incidence in vehicles used primarily for short urban journeys. Peugeot service documentation recommends preventative cleaning, while owner data suggests this is a frequent cause of performance-related complaints. Neglecting AdBlue refills will immobilize the vehicle, making adherence to dashboard warnings critical.
Analysis derived from Peugeot technical bulletins (2021-Present) and owner club failure statistics (compiled 2022-2024). 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 HNZ is a modern, efficient engine designed for low emissions. Its main vulnerabilities are the EGR cooler and the AdBlue/SCR emissions equipment. With regular long-distance driving to keep the EGR and DPF clean, and timely AdBlue refills, these engines are very reliable. Neglecting these systems will lead to expensive repairs and potential immobilization.
The most frequent issues are clogging of the EGR cooler, AdBlue system faults or depletion leading to start-lock, and DPF regeneration problems. Turbocharger actuator faults are also documented. All are well-known in Peugeot service bulletins and have established diagnostic and repair procedures.
The HNZ (EB2DT) is used in the latest generation Peugeot 208 (2021-Present) and Peugeot 2008 (2021-Present) as the 1.5 BlueHDi 115 variant. It is the successor to the FHZ engine and is not used in any other Peugeot or Citroën models.
Aftermarket ECU tuning is common on the HNZ-EB2DT platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Fuel economy is outstanding for a diesel. Expect around 4.0-4.5 L/100km (71-63 mpg UK) in mixed driving for a Peugeot 208. Highway cruising can yield 3.5-4.0 L/100km (81-71 mpg UK). Consumption will increase if the DPF or EGR system is malfunctioning or if driving is predominantly urban with short trips.
Yes. The HNZ (EB2DT) is an interference engine. If the timing chain were to fail (though highly unlikely given its design and durability), the pistons would collide with the open valves, causing severe internal engine damage. The chain is designed to last the lifetime of the engine with proper oil changes.
Peugeot specifies a 0W-30 fully synthetic oil meeting the PSA B71 2312 standard. This is a low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil specifically formulated to protect the emissions systems (DPF, SCR) and ensure optimal performance of the low-friction engine design.
