The Peugeot VJX (TUD5) is a 1,527 cc, inline‑three naturally aspirated diesel engine produced between 1998 and 2005. It features a single overhead camshaft (SOHC) design with 6 valves and indirect injection via a Bosch rotary distributor pump. This configuration delivers a modest output of 40–44 kW (54–60 PS), prioritizing fuel economy and mechanical simplicity over performance.
Fitted to models such as the 206 and Partner, the VJX engine was engineered for urban efficiency and low-cost ownership. Emissions compliance for its production run was primarily achieved through its simple mechanical injection system and catalytic converter, meeting Euro 2 standards.
One documented concern for the VJX engine is premature failure of the crankshaft position sensor, which can cause sudden engine cut-outs or failure to start. This issue, addressed in PSA service documentation, is often linked to heat degradation of the sensor's internal components and its proximity to the exhaust manifold.
All production years (1998–2005) meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/2345).
The Peugeot VJX (TUD5) is a 1,527 cc inline‑three naturally aspirated diesel engineered for compact cars and vans (1998-2005). It combines a simple SOHC 6-valve architecture with indirect injection to deliver predictable, economical performance. Designed to meet Euro 2 emissions standards, it prioritizes durability and serviceability for high-mileage, low-cost operation.

The indirect injection system provides predictable, linear power delivery ideal for city driving but requires strict adherence to the 90,000 km or 5-year timing belt replacement interval to prevent catastrophic failure, as it is an interference engine. The Bosch VE pump is robust but sensitive to poor fuel quality; using only ultra-low-sulfur diesel (ULSD) is recommended. The crankshaft position sensor is a known failure point; carrying a spare is prudent for older vehicles.
Oil Specs: Requires PSA B71 2290 specification (PSA Service Bulletin SB-01-04). ACEA B3/B4 is the minimum acceptable standard for this engine.
Emissions: Euro 2 certification applies to all model years (1998-2005) (VCA Type Approval #VCA/EMS/2345).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model applications (PSA Group PT-2000).

UNECE Regulation No. 85 (Engine Power Measurement)
The Peugeot VJX (TUD5) was used across Peugeot's PF1 platform with transverse mounting. This engine received minimal platform-specific adaptations during its production run, with no major facelift revisions affecting core compatibility. All applications are documented in OEM technical bulletins.
Locate the engine code stamped on a flat machined surface on the front of the cylinder block, near the gearbox flange (PSA Repair Manual 6700.A0). The 8th VIN digit often corresponds to the engine code for PSA vehicles. Visually, the VJX engine can be identified by its black plastic camshaft cover with "TUD5" embossed on it and the presence of a Bosch VE rotary injection pump mounted on the side of the engine block. Critical differentiation from the turbocharged TUD5: The VJX (TUD5) is naturally aspirated and lacks a turbocharger or intercooler piping.
The VJX (TUD5)'s primary reliability risk is crankshaft position sensor failure, with elevated incidence in vehicles subjected to high ambient temperatures or prolonged driving. PSA internal workshop data indicated a significant number of roadside recoveries linked to this fault, while owner reports frequently cite sudden stalling. Timely sensor replacement is critical for trouble-free operation.
Analysis derived from PSA technical bulletins (1998-2005) and owner-reported failure data (2005-2023). Repair procedures should follow manufacturer guidelines.
