The Peugeot DW10FC (engine code AHH) is a 1,997 cc, inline‑four turbo‑diesel engine introduced in 2018. It features a double overhead camshaft (DOHC), 16‑valve architecture with a variable geometry turbocharger (VGT) and high‑pressure common‑rail direct injection. Peak output ranges from 110 kW (150 PS) to 132 kW (180 PS), with torque between 340–400 Nm, delivering strong low‑rpm pull and refined performance.
Fitted to models such as the Peugeot 3008 II, 5008 II, and 5…
All production years (2018–present) meet Euro 6d-TEMP (2018–2020) and Euro 6d (2021–present) standards (VCA UK Type Approval #VCA/EMS/10234).
The Peugeot DW10FC (AHH) is a 1,997 cc inline‑four turbo‑diesel engineered for midsize SUVs and sedans (2018–present). It combines DOHC valvetrain architecture with a variable-geometry turbocharger and 2,000-bar common-rail injection to deliver responsive torque and low-end refinement. Designed to meet Euro 6d emissions standards, it integrates AdBlue-based SCR for stringent NOx control.

The Peugeot DW10FC (AHH) was used across PSA Group's EMP2 platform with transverse mounting and shared with Citroën, DS, and Opel/Vauxhall. This engine received platform-specific adaptations—revised engine mounts in the 5008 II and modified AdBlue tank routing in the 508 II—and from early 2021 the updated fuel pump coupling created minor interchange limits. All adaptations are documented in OEM technical bulletins.
The DW10FC's primary reliability risk is high-pressure fuel pump drive coupling failure in pre-2021 builds, with elevated incidence in vehicles subjected to sustained motorway driving or towing. PSA internal quality reports from 2020 noted measurable coupling degradation before 120,000 km in fleet applications, while UK DVSA MOT data shows SCR/AdBlue system faults as a growing cause of test rejection. Extended oil intervals and incorrect oil specification accelerate wear, making oil discipline and AdBlue quality critical.
Analysis derived from PSA technical bulletins (2018–2022) 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 DW10FC is generally robust if maintained correctly. Early units (2018–2020) are susceptible to fuel pump coupling failure under high-load use, but 2021+ revisions improved durability. Using correct low-SAPS oil (ACEA C2/C3), adhering to service intervals, and maintaining AdBlue quality greatly enhance longevity.
Top issues include high-pressure fuel pump coupling failure, AdBlue/SCR system faults, EGR valve carbon buildup, and timing chain tensioner wear. These are documented in PSA service bulletins SI‑19‑05 and TIS updates from 2019–2021.
Primarily the Peugeot 3008 II, 5008 II, and 508 II (2018–present) in 2.0 BlueHDi 160/180 variants. It was also used in Citroën C5 Aircross, DS 7 Crossback, and Opel Grandland X during the same period under the BlueHDi or Diesel branding.
Modest ECU remapping can yield +20–25 PS safely, but the CP4.2 pump and stock turbo limit aggressive tuning. Most tuners recommend supporting upgrades (intercooler, EGR/DPF delete—where legal) only for track use. Daily-driven examples benefit more from AdBlue/EGR maintenance than power gains.
Efficient for its class: ~5.8 L/100km (city) and ~4.5 L/100km (highway), or 49–63 mpg UK combined. Real-world figures depend heavily on driving style, AdBlue consumption, and DPF regeneration cycles—consistent mixed use optimizes economy.
Yes. The DW10FC is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing severe internal damage. Prompt attention to chain rattle or timing faults is essential.
PSA specifies 0W‑30 synthetic oil meeting ACEA C2/C3 and PSA B71 2312 standards. This low-SAPS formulation protects the DPF and SCR systems and ensures proper lubrication of the cam-driven fuel pump. Change every 20,000 km or annually.
