The Citroen 4HV (P22DTE) is a 2,179 cc, inline-four turbo-diesel engine produced between 2011 and 2018. It forms part of the PSA DW12 family, widely used across Peugeot, Citroën, and DS models, featuring common rail direct injection, variable geometry turbocharging (VGT), and dual overhead camshafts (DOHC). In standard tune, it delivers 120 kW (163 PS) with peak torque of 370 Nm, providing strong mid-range performance for larger passenger and commercial vehicles.
Fitted to models such as the Citroën C5, C6, and Jumpy, as well as the Peugeot 508 and Expert, the P22DTE was engineered for refined cruising and load-carrying capability. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 5 compliance across its production run.
One documented concern is high-pressure fuel pump (HPFP) failure, particularly on early 2011–2013 builds, identified in PSA Technical Bulletin TBB01213. Failures are often linked to fuel contamination or prolonged use of substandard diesel. From 2014 onward, PSA introduced revised fuel filtration and updated HPFP calibration, reducing failure incidence and improving long-term reliability in later production units.
Production years 2011–2018 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Citroen P22DTE is a 2,179 cc inline-four turbo-diesel engineered for executive and commercial applications (2011–2018). It combines common-rail direct injection with a variable-geometry turbocharger and SCR-based aftertreatment to deliver strong mid-range torque and low CO₂ emissions. Designed to meet Euro 5 standards, it balances performance with efficiency in larger vehicle platforms.

The P22DTE delivers strong mid-range torque ideal for motorway cruising and load-carrying, but requires strict adherence to 150,000 km or 10-year timing belt replacement intervals to prevent catastrophic interference engine damage. PSA B71 2290 (5W-30) oil is essential for turbo and fuel pump longevity. Use of ultra-low-sulfur diesel (EN 590) is critical to prevent high-pressure fuel pump (HPFP) seizure. AdBlue system requires periodic refills and sensor calibration to maintain SCR efficiency. EGR and DPF systems demand regular longer runs to prevent clogging and regeneration issues in urban applications.
Oil Specs: Requires PSA B71 2290 (5W-30) specification (PSA SIB TBB01213). Supersedes ACEA C3 requirements.
Emissions: Euro 5 certification applies to all 2011–2018 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under ISO 1585 standards. Output consistent across model range with no market-specific derating.

The Citroen P22DTE was used across Citroen's C5/C6/Jumpy platforms with longitudinal mounting and shared within the PSA Group for transverse applications in commercial variants. This engine received platform-specific adaptations-shorter intake manifolds in the Jumpy and revised EGR cooling in the C6-and from 2014 the updated fuel pump calibration improved reliability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front-right side of the engine block near the starter motor (PSA TIS D12-4600). The 8th VIN digit indicates engine type ('K' for DW12 family). Pre-2014 models have a Bosch CP3 high-pressure fuel pump; post-2014 units use CP3.5 with improved sealing. Critical differentiation from DW10: P22DTE has SCR/AdBlue system with blue filler cap, while DW10 lacks SCR. Service parts require production date verification—timing belts for pre-2014 engines are incompatible with later units due to tensioner redesign (PSA SIB TBB01213).
The P22DTE's primary reliability risk is high-pressure fuel pump (HPFP) failure on early builds, with elevated incidence in urban driving with frequent short trips. PSA internal reports from 2013 indicated a significant share of pre-2014 units required HPFP replacement before 150,000 km, while UK DVSA records show SCR-related faults are common in vehicles with infrequent long-distance driving. Poor fuel quality and extended service intervals increase pump and EGR stress, making fuel filtration and oil changes critical.
