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, t…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The EHZ is generally reliable with proper maintenance. Its main weakness is the high-pressure fuel pump, which can fail prematurely if poor-quality fuel or incorrect oil is used. Adhering strictly to the service schedule, using EN 590 diesel and ACEA C2 oil, and keeping the AdBlue tank topped up are crucial for long-term reliability.
The most frequent issues are high-pressure fuel pump failure (SIB 6015 B), AdBlue system faults leading to driving bans, EGR valve clogging causing rough running, and DPF regeneration problems from short-trip driving. These are well-documented in Peugeot service bulletins and owner forums.
The EHZ (DW10FC) engine was primarily fitted to the second-generation Peugeot 3008 (2016-2021), second-generation 5008 (2016-2021), and the Partner Tepee (2015-2018). It was the 150 PS variant of the DW10 engine family used in these models.
Yes, modest power gains are possible. An ECU remap can typically increase output by 20-30 kW and 50-70 Nm by adjusting fueling and boost maps. More significant gains require upgraded intercoolers and potentially injectors. Such modifications can increase stress on the fuel pump and turbo, potentially reducing longevity if not managed carefully.
Good for its size and power. In a Peugeot 3008 GT, expect real-world figures of around 6.5 L/100km (43 mpg UK) in mixed driving and 5.5 L/100km (51 mpg UK) on the highway. The heavier 5008 will return slightly less, typically 7.0-7.5 L/100km (38-40 mpg UK) combined, depending on driving style and load.
Yes. The EHZ is an interference engine. While it uses a timing chain designed for the life of the engine, any catastrophic failure (e.g., from severe overheating) that causes the chain to jump or break will result in piston-to-valve contact and severe internal damage.
Peugeot mandates an oil meeting the ACEA C2 specification, typically a 5W-30 low-SAPS (Sulphated Ash, Phosphorus, Sulphur) synthetic oil. This is essential to protect the DPF and SCR systems from clogging. Using the wrong oil can lead to emissions system failures and reduced engine performance.
