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 engineered for a blend of refined cruising, responsive performance, and excellent fuel economy. Emissions compliance for Euro 6d-TEMP was achieved through a sophisticated exhaust aftertreatment system combining a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue injection.
One documented concern is the potential for AdBlue system faults, including injector crystallisation or NOx sensor drift, which can trigger warning lights and induce a torque reduction. This issue, referenced in Peugeot Service Bulletin 13BZ01A, is often linked to infrequent long-distance driving that prevents the system from completing its full regeneration and purging cycles.
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 engine provides strong, accessible torque ideal for highway merging and towing but requires regular long-distance driving to ensure the AdBlue/SCR system functions correctly and prevents crystallisation. Using only PSA B71 2290 (0W-30) oil is critical for maintaining turbo and aftertreatment system health. Short, urban trips can lead to DPF saturation and AdBlue system faults, triggering warning lights. Vehicles used primarily for short journeys should have the AdBlue system checked proactively. The timing chain is generally robust but relies on strict oil change intervals for longevity.
Oil Specs: Requires PSA B71 2290 (0W-30) specification (PSA Owner's Manual 2018).
Emissions: Euro 6d-TEMP certification applies to all 2018-2023 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across applications (PSA TIS Doc. DW10CE-03).

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.
Locate the engine code stamped on the front face of the cylinder block, near the alternator (PSA TIS DW10CE-05). The 8th VIN digit for this engine family is typically 'R'. The engine is visually identified by its black plastic cam cover with "DW10" casting and the AdBlue tank located in the spare wheel well. Critical differentiation from earlier DW10 variants: The AHY has a single, centrally mounted NOx sensor upstream of the SCR catalyst, whereas some predecessors had two sensors. Service parts are generally consistent across model years but verify using the engine's full serial number against the PSA ETK.
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.
