The Peugeot BHY (DV6FD) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2015 and 2021. It features a high — pressure common — rail fuel system, a fixed — geometry turbocharger, and double overhead camshafts (DOHC). This 16 — valve unit delivers 88 kW (120 PS) and 300 Nm of torque, with its compact displacement tuned for agile urban performance and efficient highway cruising.
Fitted to models such as the 208 II, 308 II, and 2008 II—including variants like the 20…
Production years 2015–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/6789).
The Peugeot BHY (DV6FD) is a 1,560 cc inline‑four turbo‑diesel engineered for compact hatchbacks and crossovers (2015-2021). It combines high-pressure common-rail injection with a fixed-geometry turbocharger to deliver brisk low-end response and frugal long-distance economy. Designed to meet Euro 6 standards, it balances urban agility with strict emissions control.

The Peugeot BHY (DV6FD) was used across PSA Group's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the 2008 SUV and revised exhaust routing in the 308-with no major facelift revisions affecting core compatibility. All adaptations are documented in OEM technical bulletins.
The BHY (DV6FD)'s primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using poor-quality fuel or irregular maintenance. PSA internal reports indicate a notable rate of pump replacement within the first 80,000 km, while UK DVSA data shows fuel system faults are a common cause of roadside breakdowns. Ignoring fuel quality and oil change intervals makes preventative maintenance critical.
Analysis derived from PSA technical bulletins (2015-2020) 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 BHY offers excellent fuel economy and strong low-end torque, but its long-term reliability is heavily dependent on fuel quality and maintenance. The high-pressure fuel pump is its primary weakness. Using high-quality diesel and adhering to oil change intervals is crucial. Well-maintained examples can exceed 150,000 km without major issues.
The most frequent and critical issue is high-pressure fuel pump failure, often linked to poor fuel quality. Other common problems include AdBlue system faults (injector blockage, sensor failure), DPF regeneration issues due to driving style, and EGR valve carbon buildup. These are well-documented in PSA service bulletins.
This 1.6L BlueHDi engine was used in the Peugeot 208 II (2015-2021), 308 II (2015-2021), and 2008 II (2016-2021), always badged as the 1.6 BlueHDi 120. It was also shared with Citroën models like the C3 Picasso (2015-2017) and C4 Cactus (2015-2020).
Yes, ECU remapping is possible and can safely increase power to around 140-150 PS and torque to 330-350 Nm. The stock internals are generally capable of handling this. However, tuning increases stress on the clutch and fuel system, making high-quality fuel even more critical to avoid pump failure.
Official combined figures are around 3.8 L/100km (74 mpg UK) for the 208, but real-world consumption is typically 4.5-5.5 L/100km (51-63 mpg UK) depending on model, driving style, and journey type. City driving yields the best economy due to its low-end torque.
Yes. Like virtually all modern engines, the BHY is an interference design. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic engine damage. Fortunately, the chain is very durable with proper oil maintenance.
Peugeot mandates oil meeting the PSA B71 2290 specification, typically a 5W-30 low-SAPS (low ash) synthetic. This is critical to protect the DPF and SCR systems from clogging. Using the wrong oil can lead to expensive emissions system repairs.
