The Peugeot BHX (DV6FCU) is a 1,560 cc, inline‑four turbo‑diesel engine produced between 2015 and 2021. It features an all — aluminium block and head, a high — pressure common — rail fuel system, and a variable geometry turbocharger (VGT). In its 88 kW (120 PS) tune, it delivers 300 Nm of torque, with the VGT providing responsive, lag — free performance from low revs.
Fitted to models such as the 208 II, 308 II, and 3008 II, the BHX (DV6FCU) was engineered for agile, efficient urba…
Production years 2015–2021 meet Euro 6b/6c/6d-TEMP standards .
The Peugeot BHX (DV6FCU) is a 1,560 cc inline‑four turbo‑diesel engineered for compact and mid-size hatchbacks/SUVs (2015-2021). It combines an all-aluminium construction with a high-pressure common-rail system and VGT to deliver light, responsive performance and quiet, refined operation. Designed to meet Euro 6 emissions standards, it prioritizes low fuel consumption alongside urban drivability.

The Peugeot BHX (DV6FCU) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the 308 for NVH refinement-and no major facelift revisions during its production run, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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 BHX (DV6FCU) is a refined and efficient engine, but its long-term reliability hinges on the high-pressure fuel pump, which is a known weak point. Vehicles maintained with strict 20,000 km oil changes using the correct 0W-30 oil tend to fare much better. Neglecting AdBlue top-ups or frequent short trips can also lead to costly DPF issues.
The most frequent issues are high-pressure fuel pump (HPFP) drive gear failure, DPF clogging from short trips, AdBlue system faults (injector/sensors), and carbon buildup on the EGR valve. These are well-documented in PSA service bulletins and owner reports, with the HPFP being the most critical concern.
This 1.5L BlueHDi 120 engine was used in the second-generation 208, 308, and 3008 from 2015 to 2021. It was typically fitted to mid-to-high-spec trims like Allure, GT, and GT Line across these compact and mid-size models.
Aftermarket ECU tuning is common on the BHX-DV6FCU platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Official combined figures are around 4.0-4.5 L/100km (70-63 mpg UK). Real-world economy varies: expect 5.0-6.5 L/100km (56-43 mpg UK) in mixed driving, heavily influenced by DPF regeneration cycles, driving style, and traffic conditions.
Yes. Like virtually all modern engines, the BHX (DV6FCU) is an interference design. If the timing chain were to fail, the pistons would collide with the valves, causing catastrophic engine damage. Fortunately, the chain is generally very durable with proper maintenance.
Peugeot mandates a specific 0W-30 synthetic oil meeting the PSA B71 2312 specification. Using the correct oil is critical for the longevity of the turbocharger, fuel pump, and emissions systems. Change intervals should not exceed 20,000 km or 12 months.
