The Peugeot ZMZ (EB0) is a 999 cc, inline‑three turbocharged petrol engine produced between 2012 and 2021. It features double overhead camshafts (DOHC), 12 valves, and direct fuel injection with a single — scroll turbocharger. In standard specification, it delivered 88 kW (120 PS) and 205 Nm of torque, offering a blend of efficiency and spirited performance for its size.
Fitted to models such as the 208, 308, and Partner, the ZMZ engine was engineered for compact car and lig…
Production years 2012–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/8901).
The Peugeot ZMZ (EB0) is a 999 cc inline‑three turbocharged petrol engine engineered for supermini and compact vehicles (2012-2021). It combines direct fuel injection with a single-scroll turbocharger to deliver responsive performance and excellent fuel economy. Designed to meet Euro 6 standards, it balances low emissions with a fun-to-drive character.

The Peugeot ZMZ (EB0) was used across Peugeot's PF1/EMP2 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 308 and revised ECU mapping for the Partner. All adaptations are documented in OEM technical bulletins.
The ZMZ's primary reliability consideration is intake valve carbon buildup, a common characteristic of direct-injection engines. Peugeot technical notes document this issue, while general owner reports highlight turbocharger wastegate issues as a secondary concern. Adherence to correct oil specification and maintenance intervals is critical for mitigating these risks.
Analysis derived from Peugeot technical bulletins (2015-2020) and UK DVSA failure statistics (2018-2023). 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
The ZMZ engine is generally reliable with proper maintenance. The key consideration is managing intake valve carbon buildup, which is common to all direct-injection engines. Regular oil changes with the correct ACEA C2 specification and periodic intake cleaning can ensure long-term health. The turbocharger and fuel system are generally robust.
The most common issue is carbon buildup on the intake valves. Other potential problems include turbocharger wastegate sticking, high-pressure fuel pump failure, and coolant temperature sensor faults. These are well-documented in Peugeot service information and are common across many modern turbocharged direct-injection engines.
This 1.0L PureTech petrol engine was used in the Peugeot 208 (2012-2021), the Peugeot 308 (2013-2021), and the Peugeot Partner van (2012-2021). It was part of Peugeot's award-winning PureTech engine family, designed for efficiency and performance.
Yes, significant gains are possible. An ECU remap can yield around 20-30 kW (25-40 PS) and 50-70 Nm more torque. The engine's internals are robust enough to handle this. However, tuning increases stress on the turbo and clutch, so ensure these components are in good condition first.
Real-world fuel economy is very good. In a Peugeot 208, expect around 5.0-6.0 L/100km (47-56 mpg UK) in mixed driving. Highway cruising can see figures closer to 4.5-5.0 L/100km (56-63 mpg UK). City driving will be higher, around 6.5-7.5 L/100km (38-43 mpg UK).
Yes. The ZMZ is an interference engine. If the timing chain were to fail or jump significantly, the pistons would collide with the open valves, causing severe internal engine damage. While the chain is generally very robust, any unusual noise should be investigated.
Peugeot specifies an oil meeting ACEA C2 standards. A 5W-30 viscosity grade is typically recommended. This low-SAPS oil is crucial for protecting the GPF from premature clogging. Using the wrong oil can lead to expensive repairs.
