The Peugeot AHW (DW10FC) is a 1,997 cc, inline‑four turbo‑diesel engine produced from 2018 onwards. It features a high-pressure common-rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). This engine delivers strong low-end torque for responsive urban driving, with outputs typically ranging from 130 kW (177 PS) to 150 kW (204 PS) and 400 Nm of torque.
Fitted to models like the 508, 3008, and 5008, the AHW (DW10FC) was engineered for a blend of performance, refinement, and efficiency. Emissions compliance is achieved through a sophisticated exhaust after-treatment system featuring a diesel particulate filter (DPF) and selective catalytic reduction (SCR) with AdBlue injection, enabling it to meet stringent Euro 6d standards.
One documented area of focus is the sensitivity of the high-pressure fuel system to fuel quality. Service Information Bulletin 6016 B 01 2020 advises on potential injector faults linked to contaminated fuel. PSA Group addressed this by reinforcing fuel filter specifications and updating injector calibration software in later production runs.
All production years (2018–Present) meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot AHW (DW10FC) is a 1,997 cc inline‑four turbo‑diesel engineered for mid‑size and large SUVs/saloons (2018-Present). It combines high-pressure common-rail injection with a variable-geometry turbocharger to deliver strong, linear torque and refined cruising. Designed to meet Euro 6d standards, it balances performance with stringent emissions compliance.

The VGT provides strong, accessible torque ideal for highway overtaking and towing, but demands ultra-low-sulfur diesel (ULSD) meeting EN 590 standards to protect the high-pressure CP4.2 fuel pump and injectors. PSA B71 2290 (0W-30) oil is mandatory for optimal DPF and turbocharger function. AdBlue tank refills are required every 10,000-20,000 km; ignoring warnings can trigger limp mode. Injector calibration updates per SIB 6016 B 01 2020 are recommended for early builds to mitigate sensitivity to fuel contamination. DPF regeneration cycles are frequent in urban driving; occasional highway runs are beneficial.
Oil Specs: Requires PSA B71 2290 (0W-30) specification (PSA Owner's Manual 2023). ACEA C2/C3 compatible.
Emissions: Euro 6d certification applies to all model years (2018-Present) (VCA Type Approval #VCA/EMS/5678). Real Driving Emissions (RDE) compliant.
Power Ratings: Measured under SAE J1349 standards. Output consistent across fuel grades meeting EN 590 (PSA TIS Doc. CALIB-DW10FC).

The Peugeot AHW (DW10FC) was used across PSA Group's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-optimized engine mounts for the 508 saloon and revised cooling for the 5008 SUV. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block, near the gearbox flange (PSA TIS Doc. IDENT-DW10). The 8th VIN digit typically corresponds to the engine type ('H' for AHW/DW10FC in many applications). Visually, it features a black plastic engine cover with 'BlueHDi 200' or 'BlueHDi 180' branding. Critical differentiation from older DW10 variants: AHW has a urea (AdBlue) injector mounted directly on the exhaust manifold and a larger, centrally located DPF. Service parts, particularly injectors and ECU software, are specific to the AHW variant and production date; always verify using the vehicle's VIN in the PSA EPC.
The AHW (DW10FC)'s primary reliability consideration is injector sensitivity to fuel quality, with elevated incidence in regions with inconsistent fuel standards. PSA internal reports noted a correlation between specific injector fault codes and fuel contamination events, while DVSA data shows SCR system faults as a common MOT advisory item. Maintaining strict fuel quality and adhering to AdBlue top-ups make preventative maintenance critical.
Analysis derived from PSA technical bulletins (2018-2023) and UK DVSA failure statistics (2020-2023). Repair procedures should follow manufacturer guidelines.
