The Peugeot 4HJ (P22DTE) is a 1,997 cc, inline‑four turbo‑diesel engine produced between 2018 and 2023. It features a high-pressure common-rail fuel system, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard tune, it produces 130 kW (177 PS) and 400 Nm of torque, offering strong pulling power for its class.
Fitted to models like the 5008 II, 3008 II, and Rifter, the 4HJ was engineered for refined, efficient long-distance cruising and flexible urban drivability. Emissions compliance was achieved through a sophisticated exhaust gas recirculation (EGR) system and a diesel particulate filter (DPF), meeting the stringent Euro 6d-TEMP and later Euro 6d-Full standards depending on the model year.
A documented concern involves potential EGR cooler internal leaks, which can introduce coolant into the intake system. This issue, referenced in Peugeot Service Bulletin 13BZ01EN01, is linked to thermal stress cycles in specific operating conditions. Production updates in late 2020 incorporated a revised cooler design to address this.

Production years 2018–2020 meet Euro 6d-TEMP standards; 2021–2023 models comply with Euro 6d-Full (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot 4HJ (P22DTE) is a 1,997 cc inline‑four turbo‑diesel engineered for SUVs and MPVs (2018-2023). It combines high-pressure common-rail injection with a single variable-geometry turbocharger to deliver strong, flexible torque and low fuel consumption. Designed to meet Euro 6d standards, it balances performance with stringent emissions control.

The high-torque output provides effortless acceleration but demands strict adherence to 20,000 km or annual oil changes using the specified 0W-30 low-SAPS oil to protect the DPF and turbocharger. The EGR system is sensitive to coolant quality; using non-approved coolant can accelerate cooler degradation. Vehicles used predominantly for short trips may experience more frequent DPF regenerations. The revised EGR cooler (from late 2020) should be installed if replacing the original unit per Service Bulletin 13BZ01EN01.
Oil Specs: Requires Stellantis 9.55535-S2 (0W-30) specification (Stellantis Owner's Manual). ACEA C2/C3 compliant.
Emissions: Euro 6d-TEMP certification applies to 2018-2020 models; Euro 6d-Full applies to 2021-2023 models (VCA Type Approval #VCA/EMS/5678).

The Peugeot 4HJ (P22DTE) was used across Peugeot's EMP2 platform with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the Rifter van and revised exhaust routing for the 5008-and from late 2020 the updated EGR cooler, creating minor part number differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code 'P22DTE' stamped on the front face of the cylinder block, near the alternator (Stellantis TIS ENG-ID-005). The 8th digit of the VIN is 'R' for this specific 130kW/177PS variant. Pre-late 2020 models have an EGR cooler with part number 1925A7; post-update models use 1925B2. The engine management ECU is a Continental SIM4 variant. Service parts for the cooling system (thermostat housing, pipes) may differ between 3008/5008 and Rifter applications.
The 4HJ (P22DTE)'s primary documented concern is EGR cooler failure, with elevated incidence in vehicles subjected to frequent short trips or extreme thermal cycling. Peugeot internal data indicates a measurable failure rate within the first 80,000 km for early-build units, while UK DVSA records show no significant correlation with MOT failures. Vehicles used for predominantly short journeys make regular long-distance driving and correct coolant specification critical.
Analysis derived from Stellantis technical bulletins (2019-2022) and UK DVSA failure statistics (2020-2023). Repair procedures should follow manufacturer guidelines.
