The Peugeot AHY (DW10CE) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. It features a high — pressure common — rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form, it delivers 130 kW (177 PS) and 400 Nm of torque, with the VGT enabling strong low — rpm pulling power for effortless overtaking and towing.
Fitted to models such as the 5008 II, 3008 II, and Rifter, the AHY engine was engineer…
Production years 2018–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot AHY (DW10CE) is a 1,997 cc inline‑four turbo‑diesel engineered for SUVs and MPVs (2018-2023). It combines high-pressure common-rail injection with a variable-geometry turbocharger to deliver strong, linear torque and refined operation. Designed to meet stringent Euro 6d-TEMP standards, it balances performance with low emissions.

The Peugeot AHY (DW10CE) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-optimised mounts for the 5008 and revised cooling for the Rifter-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
The AHY (DW10CE)'s primary reliability risk is AdBlue system faults, with elevated incidence in vehicles used for predominantly short urban journeys. PSA service data indicates a correlation between low annual mileage and increased frequency of NOx sensor or injector-related faults, while VCA emissions test data shows these faults are a leading cause of non-compliance for this engine type. Infrequent long-distance driving makes proactive system checks critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AHY engine is generally robust mechanically, with a durable timing chain and strong internals. Its long-term reliability is heavily dependent on usage; vehicles driven long distances regularly fare best. The main concerns are the AdBlue and DPF systems, which can become problematic with short, urban trips. Strict adherence to oil specifications and service intervals is paramount.
The most frequent issues are AdBlue system faults (injector crystallisation, NOx sensor failure), DPF saturation from short trips, and EGR valve clogging. Turbo actuator failures are also documented, though less common. These are covered in PSA service bulletins like 13BZ01A.
The 1.6L AHY (DW10CE) diesel was used in Peugeot's EMP2 platform vehicles from 2018-2023, specifically the 3008 II SUV, 5008 II MPV, and Rifter MPV. It was typically fitted to higher trim levels like GT and GT Line, producing 177 PS.
Yes, ECU remapping is common and can yield safe power gains of 20-30 kW (27-40 PS) and increased torque. The engine's internals and turbo can handle moderate increases. However, tuning can exacerbate DPF and AdBlue system issues, especially on cars not used for long journeys, and may void the warranty.
Official combined figures are around 5.0-5.5 L/100km (56-51 mpg UK) depending on the model and wheel size. Real-world economy for mixed driving is typically 6.0-7.0 L/100km (47-40 mpg UK). Short trips and urban driving will significantly reduce this figure due to DPF regeneration cycles.
Yes. Like virtually all modern engines, the AHY (DW10CE) is an interference design. If the timing chain were to fail catastrophically, the pistons would collide with the open valves, causing severe internal engine damage requiring a rebuild or replacement.
Peugeot mandates the use of low-ash, fully synthetic oil meeting the PSA B71 2290 specification, typically in 0W-30 viscosity. Using the correct oil is non-negotiable to protect the DPF from clogging and ensure the longevity of the turbocharger and timing chain.
