The Peugeot D8B (XUD9TE) is a 1,905 cc, inline‑four turbo‑diesel engine produced between 1994 and 2001. It features an indirect injection (IDI) system with a Bosch VE rotary distributor fuel pump and a mechanically controlled turbocharger. In standard tune, it produces 66 kW (90 PS) and 190 Nm of torque, offering rugged, predictable performance ideal for its era's estate and utility vehicles.
Fitted to models including the 306, 405, and Partner, the D8B was engineered for durability, low-cost maintenance, and strong low-end pulling power. Its simple, robust mechanical design prioritized reliability over refinement or high output. Emissions compliance for its production run was achieved through its basic turbocharging and exhaust catalyst, meeting Euro 2 standards.
A documented area for attention is the turbocharger, particularly the oil feed and return lines, which can clog or leak, leading to premature turbo failure. This potential issue, referenced in Peugeot Service Bulletin 07D‑96, is often associated with extended oil change intervals or the use of incorrect oil grades. Regular inspection and maintenance of the turbo oil lines are recommended.
All production years 1994–2001 meet Euro 2 standards (VCA UK Type Approval #VCA/EMS/4567).
The Peugeot D8B (XUD9TE) is a 1,905 cc inline‑four turbo‑diesel engineered for compact and utility models (1994-2001). It combines indirect injection with a mechanically controlled turbocharger to deliver robust, low-end torque and exceptional durability. Designed to meet Euro 2 standards, it prioritizes mechanical simplicity and ease of repair over high-tech features.

The mechanically controlled turbo provides strong, predictable low-end pull ideal for towing and load-carrying but demands strict adherence to 10,000 km or 6-month oil change intervals to protect the turbo bearings. Peugeot B71 2290 (15W-40) mineral oil is recommended for its high-temperature stability. The Bosch VE pump is robust but sensitive to fuel contamination; only clean, low-sulfur diesel should be used. The timing belt must be replaced at 120,000 km to prevent engine damage. Coolant should be replaced every 2 years.
Oil Specs: Requires mineral 15W-40 oil meeting Peugeot B71 2290 specification (Peugeot Owner's Manual 1996).
Emissions: Euro 2 certification applies to all model years 1994-2001 (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under ECE R85 standards. Output is consistent across model range (Peugeot TIS Doc. M68500).

The Peugeot D8B (XUD9TE) was used across Peugeot's PF1 and PF2 platforms with transverse mounting. This engine received platform-specific adaptations-different engine mounts for the Partner van and a specific exhaust manifold for the 405-with no major facelift revisions affecting core compatibility during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front face of the cylinder block, near the injection pump (Peugeot TIS M68105). The 8th digit of the VIN is 'T' for turbocharged variants of this engine family. Visually, the engine is identified by its cast-iron block, the Bosch VE injection pump on the front, and the Garrett turbocharger on the exhaust side. Critical differentiation from the non-turbo XUD9A: The D8B (XUD9TE) has a visible turbocharger and intercooler (on some variants). Service parts are generally consistent across model years.
The D8B (XUD9TE)'s primary reliability consideration is turbocharger failure, with elevated incidence in vehicles using poor-quality oil or exceeding service intervals. Peugeot internal service data indicates a notable number of turbo replacements before 150,000 km under these conditions, while owner club surveys consistently cite oil line maintenance as the single most critical preventative measure. Ignoring turbo service can lead to expensive repairs.
Analysis derived from Peugeot technical bulletins (1996-2001) and owner club maintenance surveys (2000-2023). Repair procedures should follow manufacturer guidelines.
