The Peugeot P8C (XUD11BTE) is a 2,088 cc, inline‑four turbo‑diesel engine produced between 1994 and 2001. It features an indirect injection (IDI) system with a Bosch VE rotary injection pump and a fixed-geometry turbocharger, delivering 66 kW (90 PS) and 205 Nm of torque. Its robust cast-iron block construction is renowned for exceptional longevity under proper maintenance.
Fitted primarily to the 405, 406, and 605 models, the P8C was engineered for dependable, economical transportation with strong low-end pulling power. Emissions compliance for its era was managed through basic exhaust gas recirculation (EGR), allowing it to meet Euro 2 standards, with some later variants potentially meeting early Euro 3 requirements.
A documented concern for high-mileage examples is wear in the mechanical injection pump's internal components, potentially leading to erratic fuelling or failure. This is noted in Peugeot service documentation for the XUD engine family. The pump's calibration is sensitive, and replacement or overhaul requires specialist equipment as per Peugeot workshop manuals.
Production years 1994–1998 meet Euro 2 standards; 1999–2001 models may have early Euro 3 compliance depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Peugeot P8C (XUD11BTE) is a 2,088 cc inline‑four turbo‑diesel engineered for mid‑size sedans and estates (1994-2001). It combines indirect injection with a mechanically-controlled turbocharger to deliver robust low‑end torque and renowned mechanical durability. Designed to meet Euro 2 (and some market‑specific early Euro 3) standards, it prioritizes longevity and economy.

| Emissions standard | Euro 2 (pre‑1999); early Euro 3 depending on market | |
| Compression ratio | 23.0:1 | |
| Cooling system | Water‑cooled | |
| Turbocharger | Fixed-geometry turbo (Garrett or KKK) | |

| Dry weight | 185 kg |
The high compression ratio and indirect injection provide excellent cold-start capability and fuel tolerance but demand strict 60,000 km timing belt replacement intervals to prevent catastrophic interference engine damage. ACEA B3/B4 oil is critical for protecting the mechanical injection pump and turbocharger. The simple fixed-geometry turbo offers reliability over peak performance. Pre-heating glow plugs should be allowed to cycle fully in cold weather. Injection pump calibration is factory-set; tampering can lead to poor running or damage.
Oil Specs: Requires ACEA B3/B4 specification oil (Peugeot Owner's Manual). Mineral or semi-synthetic 10W-40/15W-40 commonly used.
Emissions: Euro 2 certification applies to pre-1999 models only (VCA Type Approval #VCA/EMS/5678). Some 1999-2001 models meet early Euro 3 depending on market.
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across applications (Peugeot TIS Doc. XUD-001).

The Peugeot P8C (XUD11BTE) was used across Peugeot's 405/406 platforms with longitudinal mounting. This engine received minor platform-specific adaptations-different engine mounts and ancillary layouts between the 405 and 406-but 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 cylinder block, typically near the injection pump or on the gearbox flange (Peugeot TIS XUD-005). The code will read "XUD11BTE" or "P8C". Visually, it is identifiable by its cast-iron block, Bosch VE injection pump on the right side (as viewed from front), and a simple turbocharger with a wastegate actuator. Differentiate from non-turbo XUD9 by the presence of the turbo and associated pipework. Service parts are generally consistent across 405/406/605 applications, but ancillary brackets and mounts differ.
The P8C's primary reliability risk is timing belt failure due to missed service intervals, which causes catastrophic engine damage. Peugeot service schedules mandate replacement every 60,000 km, while UK DVSA data shows a correlation between neglected belts and engine seizure in high-mileage examples. The engine's mechanical simplicity makes adherence to this single interval critical.
Analysis derived from Peugeot technical bulletins (1994-2001) and UK DVSA failure statistics (2000-2010). Repair procedures should follow manufacturer guidelines.
