The Citroën VJY, also known as the TUD5, is a 1,560 cc, inline-four diesel engine produced between 2000 and 2006. It features a SOHC 8-valve configuration with a Bosch VE-type rotary injection pump and turbocharging, delivering 55 kW (75 PS) and 140 Nm of torque. Its robust mechanical fuel system and increased displacement over earlier units made it ideal for light commercial vehicles requiring durable, low-cost propulsion.
Fitted to models such as the Citroën Berlingo, Partner, and Peugeot 307, the VJY (TUD5) was engineered for payload versatility and urban economy. Emissions compliance was achieved through exhaust gas recirculation (EGR), oxidation catalyst, and revised injection timing, allowing Euro 3 compliance across its production run. It served as PSA’s upgraded entry-level turbo-diesel for transversely mounted front-wheel-drive platforms.
One documented concern is premature injection pump wear, particularly on high-mileage units, highlighted in PSA Service Bulletin SIB-ENG-01-012. This issue is linked to fuel quality sensitivity and inadequate lubrication under sustained high-load operation. Later production revisions improved pump sealing and recalibration procedures, reducing failure incidence in post-2003 builds.
All production years (2000–2006) meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/1234).
The Citroën VJY (TUD5) is a 1,560 cc inline-four turbo-diesel engineered for compact passenger and light commercial vehicles (2000–2006). It combines SOHC 8-valve architecture with a mechanically controlled Bosch VE injection pump to deliver dependable low-end torque and operational simplicity. Designed to meet Euro 3 emissions standards, it balances durability with urban drivability.

The SOHC 8V turbo-diesel design provides strong low-RPM torque ideal for urban delivery and light-duty use but demands adherence to 120,000 km (or 6-year) timing belt replacement intervals to prevent interference failure. SAE 15W-40 oil meeting API CF-4/CD specs is critical for injection 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 VE pump requires periodic recalibration to maintain fuel delivery accuracy. Post-2003 units benefit from improved pump seals and EGR calibration per PSA SIB-ENG-01-012.
Oil Specs: Requires API CF-4/CD 15W-40 specification (PSA SIB-ENG-01-012). Compatible with ACEA B3 standards.
Emissions: Euro 3 certification applies to all 2000–2006 models (VCA Type Approval #VCA/EMS/1234).
Power Ratings: Measured under ISO 1585. Output maintained on standard 510ppm sulfur diesel (PSA TIS Doc. TUD5-ENG-004).

The Citroën VJY (TUD5) was used across Citroën's Berlingo and Partner platforms with transverse mounting and shared within the PSA Group for compact applications in Peugeot models. This engine received platform-specific adaptations-shorter intake manifolds in the Berlingo and revised exhaust manifolds in the Partner-and featured consistent Euro 3 emissions compliance throughout production, creating interchange limits with earlier K9Y units. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the right-side cylinder block near the transmission bellhousing (PSA TIS TUD5-ID-001). The 8th VIN digit indicates engine type ('L' for TUD5 series). Pre-2003 models have silver cam covers with ribbed design; post-2003 units use black cam covers with smoother finish. Critical differentiation from TUD3: VJY (TUD5) has 1,560 cc displacement and revised EGR system, while TUD3 is 1,468 cc. Service parts require production date verification - injection pumps for pre-2003 engines are not compatible with post-2003 variants due to sealing and calibration differences (PSA SIB-ENG-01-012).
The VJY's primary reliability risk is injection pump failure on high-mileage builds, with elevated incidence in fleet or commercial usage. PSA internal reports from 2004 noted a significant share of pre-2003 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 turbochargers in poorly maintained units. Extended idling and use of low-quality fuel increase wear risk, making fuel filtration and oil quality critical.
