The Peugeot EHZ (DW10FDCU) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2010 and 2018. It features a DOHC 16‑valve architecture, common rail direct injection, and a variable geometry turbocharger (VGT). In standard form, it delivered 120 kW (163 PS) and 340 Nm of torque, offering a refined blend of performance and efficiency for its class.
Fitted to the 508 saloon, 3008 crossover, and 5008 MPV, the EHZ was engineered for smooth, responsive power delivery and low running costs. Emissions compliance for its production period was met through a diesel particulate filter (DPF) and exhaust gas recirculation (EGR), aligning with Euro 5 standards. Its character prioritized refinement and mid‑range flexibility over raw power.
One documented concern is premature failure of the high-pressure fuel pump, which can lead to engine non-start conditions. This issue, referenced in Peugeot Technical Note 10567/A, is often linked to fuel contamination or extended service intervals. The problem was addressed in later DW10 variants through revised pump designs and stricter fuel filtration.
Production years 2010–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/8765).
The Peugeot EHZ (DW10FDCU) is a 1,997 cc inline‑four turbo‑diesel engineered for mid‑size and large MPVs/saloons (2010-2018). It combines common rail direct injection with a variable geometry turbocharger to deliver smooth, flexible power and strong fuel economy. Designed to meet Euro 5 standards, it balances modern performance with environmental compliance.

The variable geometry turbo provides smooth, lag-free power delivery but requires strict 20,000 km oil changes with ACEA C2/C3 specification oil to protect the turbo and DPF system. The Bosch CP4 high-pressure fuel pump is sensitive to fuel contamination; use only high-quality, low-sulfur diesel (EN 590) to prevent premature failure. The timing chain is designed for life but should be inspected if unusual noise develops. DPF regeneration cycles are automatic but require regular highway driving to complete effectively.
Oil Specs: Requires ACEA C2 or C3 specification (Peugeot Owner's Manual 2012). Compatible with SAE 5W-30 viscosity grade.
Emissions: Euro 5 certification applies to all 2010-2018 models (VCA Type Approval #VCA/EMS/8765). No market-specific variations.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across all applications (Peugeot TIS Doc. DW10-Spec).

The Peugeot EHZ (DW10FDCU) was used across Peugeot's PF2/PF3 platforms with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 508-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, near the gearbox flange (Peugeot TIS DW10-ID). The code "EHZ" is clearly visible. Visually, it is identifiable by its DOHC 16-valve cylinder head, Bosch CP4 injection pump on the rear, and a Honeywell VGT turbocharger with an electronic actuator on the front. Differentiate from the lower-powered DW10 variants by the specific power output and ECU mapping. Service parts are generally compatible across all EHZ applications.
The EHZ (DW10FDCU)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel. Peugeot Technical Note 10567/A documents this as a common service item, while owner reports frequently cite resulting non-start conditions. Fuel quality and service adherence make preventative maintenance critical.
Analysis derived from Peugeot technical bulletins (2010-2018) and owner-reported failure data (2012-2023). Repair procedures should follow manufacturer guidelines.
