The Peugeot BHS (DV6FDU) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2015 and 2021. It features a compact, lightweight design with a high — pressure common rail system, a fixed — geometry turbocharger, and dual overhead camshafts (DOHC). This engine was calibrated to deliver 88 kW (120 PS) and 300 Nm of torque, with its efficient combustion process prioritizing low fuel consumption for urban and suburban driving.
Fitted to models such as the 208 II, 308…
Production years 2015–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/6789).
The Peugeot BHS (DV6FDU) is a 1,560 cc inline‑four turbo‑diesel engineered for compact models (2015-2021). It combines common‑rail direct injection with a single fixed‑geometry turbocharger to deliver responsive low‑end torque and exceptional fuel efficiency. Designed to meet Euro 6 standards, it prioritizes urban economy without sacrificing drivability.

The Peugeot BHS (DV6FDU) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific ECU calibrations for the 208 and 308, with no major hardware revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
The BHS (DV6FDU)'s primary reliability risk is EGR cooler failure, with elevated incidence in vehicles subjected to frequent short trips. Peugeot internal reports noted a cluster of coolant leaks requiring replacement before 80,000 km, while UK DVSA data indicates DPF-related issues are also common in urban-use vehicles. Adherence to driving patterns and maintenance schedules is critical to mitigate these risks.
Analysis derived from Peugeot technical bulletins (2015-2021) and UK DVSA failure statistics (2018-2023). 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 BHS offers excellent fuel economy and is generally robust, but its long-term reliability is heavily influenced by driving habits. The EGR cooler is a known weak point, especially in stop-start urban use. With regular highway driving to facilitate DPF regeneration and strict adherence to maintenance, these engines can be very durable beyond 150,000 km.
The most frequent issues are internal leaks in the EGR cooler, problems with the DPF regeneration system, failures of the intake swirl flap actuator, and occasional high-pressure fuel injector faults. The EGR cooler issue is well-documented in Peugeot service bulletin 16BZ12C.
This engine was primarily used in the second-generation 208 (2015-2021), second-generation 308 (2015-2021), and the Partner van (2015-2021). It was also shared with Citroën, appearing in the C3 Picasso (2015-2017) and other PSA Group vehicles under the 1.6 BlueHDi 120 designation.
Yes, the BHS responds well to ECU remapping. Stage 1 tunes can safely increase power to around 140-150 PS and torque to 340+ Nm. The stock internals are capable, but supporting modifications are not typically needed for moderate gains. Always use a reputable tuner familiar with PSA Group ECUs.
Fuel economy is outstanding. In a 208, expect combined figures of around 3.8 L/100km (74 mpg UK). Real-world consumption typically ranges from 4.5-5.5 L/100km (51-63 mpg UK) depending on driving style, making it one of the most efficient diesel engines in its class.
Yes. Like virtually all modern engines, the BHS (DV6FDU) is an interference design. If the timing chain fails or jumps, the pistons will collide with the valves, causing catastrophic engine damage. Regular oil changes are crucial for chain longevity.
Peugeot mandates the use of ultra-low viscosity oil meeting the PSA B71 2312 specification, typically a 0W-30 viscosity. This is critical for cold-start protection, fuel economy, and DPF longevity. Using the wrong oil can lead to increased wear and emissions system problems.
