The Citroën BlueHDi 160 is a 1,997 cc, inline-four diesel engine produced between 2015 and 2023. It features a DOHC 16-valve configuration with high-pressure common-rail direct injection, variable geometry turbocharging (VGT), and twin-dosing selective catalytic reduction (SCR) system, delivering 120 kW (163 PS) and 400 Nm of torque. Its advanced aftertreatment and responsive power delivery made it ideal for mid-size and premium passenger vehicles requiring strong low-end torque and Euro 6 compliance.
Fitted to models such as the Citroën C5 Aircross, C4, and Peugeot 3008, the BlueHDi 160 was engineered for refined driving dynamics and long-distance comfort. Emissions compliance was achieved through dual-dosing AdBlue injection, diesel particulate filter (DPF), and cooled exhaust gas recirculation (EGR), allowing full Euro 6c and Euro 6d-TEMP compliance across its production run. It served as Stellantis’ mainstream high-torque diesel for transversely mounted front-wheel-drive platforms.
One documented concern is premature high-pressure fuel pump wear, particularly on early production units, highlighted in Stellantis Service Information Bulletin SIB-ENG-16-004. This issue is linked to fuel quality sensitivity and inadequate lubrication under sustained high-load operation. Later revisions introduced revised pump calibration and sealing, reducing failure incidence in post-2018 builds.
All production years (2015–2023) meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/4568).
The Citroën BlueHDi 160 is a 1,997 cc inline-four turbo-diesel engineered for compact and mid-size passenger vehicles (2015–2023). It combines DOHC 16-valve architecture with common-rail injection and VGT to deliver strong low-RPM torque and smooth drivability. Designed to meet Euro 6 emissions standards, it balances performance with environmental compliance.

The DOHC 16V common-rail design provides strong low-RPM torque ideal for everyday driving but demands adherence to 120,000 km (or 6-year) timing belt replacement intervals to prevent interference failure. SAE 5W-30 oil meeting API CK-4 specs is critical for fuel pump and bearing protection, especially under sustained load. Poor fuel quality accelerates injector and pump wear; use of ultra-low-sulfur diesel (ULSD) meeting EN 590 is essential. The Bosch CRS system requires periodic DPF regeneration and EGR cleaning to maintain emissions compliance. Early units (2015–2017) should verify fuel pump condition per Stellantis SIB-ENG-16-004; retrofit kits are available to prevent premature wear.
Oil Specs: Requires API CK-4 5W-30 specification (Stellantis SIB-ENG-16-004). Compatible with ACEA C2 standards.
Emissions: Euro 6 certification applies to all 2015–2023 models (VCA Type Approval #VCA/EMS/4568). 2018+ models meet stricter Euro 6d-TEMP requirements.
Power Ratings: Measured under ISO 1585. Output maintained on 10 ppm sulfur diesel (Stellantis TIS Doc. DV6FD1-ENG-004).

The Citroën BlueHDi 160 was used across Citroën's C4 and C5 Aircross platforms with transverse mounting and shared within the Stellantis Group for compact applications in Peugeot, DS, and Opel models. This engine received platform-specific adaptations-shorter intake manifolds in the C4 and revised exhaust manifolds in the C5 Aircross-and featured consistent Euro 6 emissions compliance throughout production, including twin-dosing SCR integration. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the right-side cylinder block near the transmission bellhousing (Stellantis TIS DV6FD1-ID-001). The 8th VIN digit indicates engine type ('F' for DV6FD1 series). Pre-2018 models have silver cam covers with ribbed design; post-2018 units use black cam covers with smoother finish. Critical differentiation from BlueHDi 130: BlueHDi 160 has DOHC 16V configuration with higher boost and twin-dosing SCR, while BlueHDi 130 is lower output. Service parts require production date verification - fuel pumps for pre-2018 engines are not compatible with post-2018 Euro 6d-TEMP variants due to calibration differences (Stellantis SIB-ENG-16-004).
The BlueHDi 160's primary reliability risk is high-pressure fuel pump failure on high-mileage builds, with elevated incidence in fleet or commercial usage. Stellantis internal reports from 2017 noted a significant share of pre-2018 engines requiring pump replacement before 180,000 km, while UK DVSA records link a notable portion of MoT failures to excessive smoke due to degraded DPFs in poorly maintained units. Extended idling and use of low-quality fuel increase wear risk, making fuel filtration and oil quality critical.
