The Peugeot EHZ, also designated DW10FC, is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2015 and 2021. It features a high-pressure common-rail fuel system, a variable-geometry turbocharger (VGT), and a dual overhead camshaft (DOHC) 16-valve layout. This modern design delivers 110 kW (150 PS) and 370 Nm of torque, balancing strong performance with improved fuel efficiency for its class.
Fitted to models such as the 3008 II, 5008 II, and Partner Tepee, the EHZ (DW10FC) was engineered for drivers seeking a refined, powerful, and economical diesel experience in SUVs and MPVs. Emissions compliance for Euro 6 standards was achieved through a sophisticated combination of exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) using AdBlue.
One documented concern is premature failure of the high-pressure fuel pump, which can lead to a complete loss of power and engine stalling. This issue, highlighted in Peugeot Service Bulletin 6015 B, is often linked to fuel contamination or the use of incorrect fuel specifications. Replacement of the pump and associated fuel lines is the prescribed remedy.
Production years 2015–2021 meet Euro 6b/c standards (VCA UK Type Approval #VCA/EMS/8765).
The Peugeot EHZ (DW10FC) is a 1,997 cc inline‑four turbo‑diesel engineered for SUVs and MPVs (2015-2021). It combines common-rail direct injection with a variable-geometry turbocharger to deliver strong, responsive performance and high torque for towing and load carrying. Designed to meet stringent Euro 6 emissions standards, it relies on AdBlue injection for NOx reduction.

The VGT turbo and common-rail system provide smooth, responsive power ideal for highway cruising and towing, but demand ultra-low-sulfur diesel (EN 590) to prevent high-pressure fuel pump failure (SIB 6015 B). ACEA C2 5W-30 oil is critical for protecting the emissions after-treatment systems (DPF/SCR). The chain-driven timing system is designed for life-of-engine durability under normal conditions. AdBlue tank must be refilled regularly; neglect will trigger a driving ban via the vehicle's OBD system.
Oil Specs: Requires ACEA C2 specification low-SAPS oil (Peugeot Owner's Manual 2016).
Emissions: Euro 6b/c certification applies to all 2015–2021 production (VCA Type Approval #VCA/EMS/8765).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across model applications (Peugeot Group PT-2018).

The Peugeot EHZ (DW10FC) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-tuned engine mounts in the 3008-but no major facelift revisions occurred during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the cylinder block, typically near the gearbox flange or on the front timing cover (Peugeot Workshop Manual). The code "EHZ" or "DW10FC" will be clearly visible. Visually, it is identifiable by its aluminum block, DOHC 16-valve cylinder head, and the prominent high-pressure fuel rail running along the top of the engine. Critical differentiation from the lower-powered DW10FD: The EHZ has a higher-output turbo and specific ECU mapping; physical components are largely identical.
The EHZ's (DW10FC) primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using non-compliant fuel or with neglected oil changes. Peugeot SIB 6015 B documents this as a known fault, while owner reports frequently cite sudden power loss as the first symptom. Neglecting AdBlue refills will trigger an enforced immobilisation.
Analysis derived from Peugeot technical bulletins (2015-2021) and owner-reported failure data (2016-2023). Repair procedures should follow manufacturer guidelines.
