PEUGEOT BHS-DVFDU engine (2015–2021) – Specs, Problems & Compatibility Database

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 II, and Partner, the BHS (DV6FDU) was engineered for agile, economical performance in compact vehicles. Emissions compliance for its entire production run was achieved through a combination of exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), meeting the stringent Euro 6 standard.

One documented reliability concern involves potential failures of the EGR cooler, which can lead to coolant leaks into the intake system. This issue, referenced in Peugeot Service Bulletin 16BZ12C, is often linked to thermal stress cycles. Later production batches incorporated a revised cooler design to mitigate this failure mode.

Production years 2015–2021 meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/6789).

BHS-DVFDU Technical Specifications

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.

Practical Implications

The fixed-geometry turbo provides predictable, linear power delivery ideal for city driving but requires strict adherence to 20,000 km or 12-month oil change intervals to protect the timing chain and turbo. Using PSA B71 2312 (0W-30) oil is critical due to its ultra-low viscosity and low-ash formulation for optimal DPF protection. The EGR system is susceptible to thermal stress; Service Bulletin 16BZ12C details the revised cooler replacement procedure for affected units. Regular highway driving is recommended to ensure effective DPF regeneration.

Data Verification Notes

Oil Specs: Requires PSA B71 2312 (0W-30) specification (Peugeot Owner's Manual). Compatible with ACEA C2.

Emissions: Euro 6 certification applies to all 2015-2021 models (VCA Type Approval #VCA/EMS/6789).

Power Ratings: Measured under SAE J1349 standards. Output is consistent across model range (Peugeot TIS Doc. B82010).

BHS-DVFDU Compatible Models

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.

Identification Guidance

Locate the engine code stamped on the flat machined surface at the front of the cylinder block, adjacent to the alternator (Peugeot TIS B81150). The engine code 'BHS' or 'DV6FDU' will be clearly visible. The 8th digit of the VIN is typically 'P' for this 120 PS variant. Visually, it can be identified by its compact size, silver plastic valve cover, and the location of the EGR valve on the rear of the engine. Critical differentiation from earlier DV6 engines: The BHS features a specific Bosch ECU (e.g., EDC17C64) with a unique connector pinout. EGR cooler part numbers must be verified against the engine serial number for compatibility (Peugeot SIB 16BZ12C).

Common Reliability Issues - PEUGEOT BHS-DVFDU

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.

EGR cooler internal leak
Symptoms: White smoke from exhaust, coolant loss without visible leaks, misfires, engine overheating.
Cause: Cracking of the internal coolant passages within the EGR cooler due to repeated thermal cycling, allowing coolant to enter the intake manifold.
Fix: Replace the EGR cooler assembly with the latest OEM-specified unit per service bulletin 16BZ12C; flush the cooling system and inspect for coolant contamination in cylinders.
DPF regeneration issues and blockage
Symptoms: Loss of power, DPF warning light, increased fuel consumption, engine may enter limp mode.
Cause: Insufficient exhaust temperatures for passive regeneration, often due to frequent short trips or a faulty differential pressure sensor.
Fix: Perform a forced regeneration via diagnostics; if blocked, clean or replace DPF. Check/replace differential pressure sensor if faulty.
Intake manifold swirl flap motor failure
Symptoms: Check Engine Light, rough idle, reduced power, diagnostic codes for swirl flap position.
Cause: Wear or electrical failure of the swirl flap actuator motor, preventing the flaps from opening or closing correctly.
Fix: Replace the swirl flap actuator motor with an OEM unit; perform ECU adaptations after installation.
High-pressure fuel injector leaks or failures
Symptoms: Rough idle, misfires, excessive smoke, fuel smell, increased fuel consumption, diagnostic codes for injector circuit/performance.
Cause: Internal wear or seal failure in the Bosch piezoelectric injectors, leading to fuel leakage into the combustion chamber or return line.
Fix: Replace the faulty injector(s) with latest OEM-specified units; reprogram injector codes via diagnostic tool and check fuel rail pressure.
