The Peugeot DV6ATED4 is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2010 and 2015. It features a dual overhead camshaft (DOHC), 16‑valve architecture, and high‑pressure common‑rail direct injection (Bosch CP4.2). Output is rated at 84 kW (115 PS) with 270 Nm of torque, engineered for strong low‑end pull and compliance with stringent emissions standards.
Fitted to models such as the Peugeot 308 (T9), 508 (XN1TACP), and Partner Tepee, the DV6ATED4 was designed for refined urban and motorway performance with low CO₂ output. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF), enabling all units to meet Euro 5 standards from launch.
One documented concern is premature high‑pressure fuel pump (HPFP) wear due to lubricity issues with ultra‑low‑sulfur diesel, highlighted in PSA Service Bulletin 09‑04‑2012. This defect leads to hard starting and loss of rail pressure. From late 2012 onward, PSA introduced revised pump internals and mandated stricter fuel quality adherence to mitigate the issue.
All production years (2010–2015) meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7532).
The Peugeot DV6ATED4 is a 1,560 cc inline‑four turbo‑diesel engine engineered for compact and mid‑size models (2010–2015). It combines DOHC 16‑valve architecture with Bosch CP4.2 common‑rail injection to deliver strong low‑rpm torque and refined operation. Designed to meet Euro 5 from launch, it balances performance with emissions compliance and fuel efficiency.

The DOHC 16‑valve turbo‑diesel layout provides strong low‑end torque ideal for mixed driving but requires strict adherence to 5W‑30 PSA 9730.B2 oil specifications to protect the timing chain and fuel system. Early DV6ATED4 engines (pre‑late 2012) are susceptible to HPFP failure due to inadequate diesel lubricity—PSA SIB 09‑04‑2012 mandates use of EN 590 diesel with minimum lubricity (HFRR ≤ 460 µm). Extended oil change intervals accelerate chain wear and turbo bearing degradation. DPF regeneration cycles must complete uninterrupted to prevent clogging and limp‑mode events.
Oil Specs: Requires PSA 9730.B2 (5W‑30 full synthetic) specification (PSA Maintenance Guide 2011). Not compatible with ACEA A3/B4 or older mineral oils.
Emissions: Euro 5 certification applies to all model years (2010–2015) under VCA Type Approval #VCA/EMS/7532.
Power Ratings: Measured under ISO 1585 standards. Requires EN 590 diesel fuel (PSA PT‑2013).

ISO 1585: Road vehicles — Engine test code
The Peugeot DV6ATED4 was used across Peugeot's T9/XN1TACP platforms with transverse mounting and shared with Citroën for badge-engineered variants. This engine received platform-specific calibrations—revised ECU maps in the 508 RXH and modified exhaust routing in the 308 SW—but retained full mechanical interchangeability across all variants. Partnerships allowed Citroën C5 and DS5 models to use identical DV6 variants. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block adjacent to the timing cover (PSA TIS M34‑820). The 7th VIN digit indicates engine family ('6' for DV6 series). All DV6ATED4 units feature a black cam cover with integrated coil packs and a single fixed‑geometry turbo. Critical differentiation from DV6DTED4: DV6ATED4 uses a fixed turbo and 115 PS output; DV6DTED4 uses a variable turbo and 120 PS. Service parts are fully interchangeable across Peugeot 508, 308, and Citroën C5 applications.
The DV6ATED4's primary reliability risk is high-pressure fuel pump (HPFP) failure in early production units, with elevated incidence in vehicles using non-compliant diesel or extended oil change intervals. PSA internal quality reports from 2013 indicated HPFP seizure in approximately 6% of pre‑late‑2012 engines before 100,000 km, while UK DVSA MOT records show DPF and EGR faults as top failure categories for 508 HDi models. Use of incorrect fuel or oil accelerates wear, making adherence to EN 590 diesel and 5W‑30 PSA 9730.B2 oil critical.
