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 f…
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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The AHW (DW10FC) is a modern, powerful engine designed for Euro 6d compliance. Its long-term reliability hinges on using high-quality fuel and oil, and adhering to AdBlue top-ups. The main documented concern is injector sensitivity, addressed in later software updates. With meticulous maintenance, it can be very dependable.
The most frequent issues are related to its emissions systems: AdBlue injector clogging, DPF regeneration problems from short trips, and EGR cooler failures. High-pressure fuel injector faults, often linked to fuel quality, are also documented in PSA service bulletins.
This 2.0L BlueHDi diesel is found in Peugeot's premium models from 2018 onwards, including the 508 (GT/GT Line), 3008 (GT/GT Line), and 5008 (GT/GT Line). It's also used in sister brands like the Citroën C5 Aircross and DS7 Crossback under the same DW10FC code.
Yes, ECU remapping is common and can safely yield significant power and torque gains (e.g., +30-50 kW). The engine's robust internals and turbo can handle moderate increases. However, tuning may increase stress on the clutch, DPF, and injectors, potentially impacting longevity and warranty.
Official combined figures range from 5.0-5.5 L/100km (51-56 mpg UK) depending on the model and drivetrain. Real-world mixed driving typically yields 6.0-7.0 L/100km (40-47 mpg UK). Fuel economy is highly sensitive to driving style and DPF regeneration cycles.
Yes. Like virtually all modern engines, the AHW (DW10FC) is an interference design. If the timing chain fails or jumps, the pistons will collide with the valves, causing catastrophic internal engine damage. Fortunately, the chain is designed for the engine's lifetime under normal conditions.
It requires a specific low-SAPS, fuel-efficient 0W-30 oil meeting the PSA B71 2290 specification. Using the correct oil is critical for protecting the turbocharger, DPF, and emissions systems. Always consult your owner's manual and change oil at recommended intervals.
