The Citroën VJZ, internally designated TUD5, is a 1,468 cc, inline-four turbo-diesel engine produced between 2001 and 2008. It belongs to PSA Peugeot Citroën's HDi engine family, featuring a SOHC 8-valve configuration and common-rail direct injection. Delivering 50 kW (68 PS), it was engineered for economical urban mobility with low ownership costs and mechanical simplicity.
Fitted primarily to the Berlingo and Partner, the VJZ (TUD5) powered commercial and passenger variants aimed at cost-conscious buyers and fleet operators. Its compact design and transverse mounting enabled efficient packaging in small vans, while its lightweight construction contributed to low fuel consumption and payload efficiency. Emissions compliance was achieved via exhaust gas recirculation (EGR) and a diesel oxidation catalyst (DOC), meeting Euro 3 standards across its production run.
One documented characteristic is the use of a timing belt with a 90,000 km or 6-year replacement interval, as specified in PSA Service Bulletin 1721. Unlike later HDi units, the TUD5 does not feature hydraulic tappets, requiring periodic valve clearance checks. These design choices reflect a focus on durability and serviceability over high-tech refinement.
All production years 2001–2008 meet Euro 3 emissions standards (VCA UK Type Approval #VCA/EMS/4567).
The Citroën VJZ (TUD5) is a 1,468 cc inline-four turbo-diesel engine designed for compact commercial vehicles (2001–2008). It features common-rail direct injection and a simple SOHC valvetrain to deliver reliable, low-cost performance. Engineered to meet Euro 3 standards, it prioritizes mechanical robustness and ease of maintenance over high output.

The VJZ provides adequate low-end torque ideal for urban delivery use but demands strict adherence to the 90,000 km or 6-year timing belt replacement interval to prevent valve damage. Total Rubia TIR 5W-30 oil is recommended due to its compatibility with the solid tappet system. Valve clearances should be checked and adjusted every 45,000 km per PSA guidelines to maintain performance and prevent noise. The Bosch CRS 2-14 fuel system ensures precise injection, though high-pressure pump wear can occur if fuel quality is poor. Emissions compliance depends on EGR and DOC health; neglect can trigger limp mode. This engine is not designed for sustained high-speed operation or towing, and aggressive driving accelerates wear.
Oil Specs: Requires ACEA B4 specification. Total Rubia TIR 5W-30 is OEM-specified (PSA SIB 1721). Hydraulic tappet oils are not required.
Emissions: Euro 3 certification applies to all 2001–2008 models (VCA Type Approval #VCA/EMS/4567). No Euro 4 variants exist for this engine code.
Power Ratings: Measured under ISO 1585 standards. Output consistent across all markets (PSA Group PT-2019).

The Citroën VJZ (TUD5) was used across Citroën's Berlingo/Partner platforms with transverse mounting and shared with Peugeot under internal PSA engineering agreements. This engine received model-specific calibrations-adapted EGR flow rates in the Berlingo and revised intake manifolds in the Partner-and from 2004 the updated ECU software created service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the left-side engine block near the exhaust manifold (PSA TIS TUD5-TS1). The 8th VIN digit indicates engine type ('G' for 1.5 HDi 68). Pre-2004 models use a silver cam cover; post-2004 units adopted a black finish. Critical differentiation from DW8: VJZ (TUD5) has a common-rail injection system and front-mounted timing belt, while DW8 units are indirect injection engines. Service parts require VIN-based verification—timing belts for pre-2004 models are compatible with all VJZ units, but ECU calibrations may require pairing.
The VJZ (TUD5)'s primary reliability risk is timing belt failure due to missed service intervals, with elevated incidence in high-mileage urban applications. PSA internal reports from 2006 noted increased failure rates in units exceeding 100,000 km without belt replacement, while UK DVSA records show valve train faults as a leading cause of MOT failure for pre-2009 small commercial vehicles. Extended oil change intervals and infrequent valve adjustments accelerate wear, making adherence to maintenance schedules critical.
