The Peugeot XUD11BTE is a 1,905 cc, inline‑four turbo‑diesel engine produced between 1995 and 2001. It features indirect injection via a Bosch VE rotary pump, a KKK K14 turbocharger, and a SOHC 8‑valve layout. In standard form it delivered 66 kW (90 PS) and 196 Nm of torque, offering robust low‑end pull and mechanical simplicity.
Fitted to models such as the 405, 406, and Partner van—including the 405 SRDT, 406 GLX TD, and Partner 1.9 TD—the XUD11BTE was engineered for durabi…
All production years 1995–2001 meet Euro 2 standards .
The Peugeot XUD11BTE is a 1,905 cc inline‑four turbo‑diesel engineered for mid‑size sedans and light commercial vehicles (1995–2001). It combines indirect injection with a KKK K14 turbocharger to deliver predictable low‑rpm torque and mechanical robustness. Designed to meet Euro 2 emissions standards, it prioritizes serviceability and long service life over peak performance.

The Peugeot XUD11BTE was used across Peugeot's 405/406 platforms with longitudinal mounting and also fitted to the Partner van. This engine received platform-specific adaptations—reinforced engine mounts in the 406 and modified exhaust routing in the Partner—and from 1998 the facelifted 406 models adopted a revised EGR cooler and turbo oil feed line, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The XUD11BTE is mechanically robust and known for longevity when properly maintained. Early models (1995–1997) are more prone to turbo oil seal issues, while post-1998 revisions improved reliability. Regular oil changes and timely timing belt replacement are essential—well-cared-for examples often exceed 300,000 km.
Top issues include turbo oil seal failure (causing blue smoke), EGR valve clogging, Bosch VE pump timing drift, and timing belt breakage in neglected engines. These are documented in Peugeot service bulletins and widely observed in fleet maintenance records.
It powered the Peugeot 405 (1995–1997), 406 (1996–2001), and Partner van (1997–2001) in 1.9 TD form. It was also used in the Citroën Xantia (1995–1998). All applications meet Euro 2 emissions and use the same core engine architecture.
Aftermarket ECU tuning is common on the XUD11BTE platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Excellent for its era. In a 406 GLX TD, expect ~6.5 L/100km (city) and ~4.8 L/100km (highway), or ~52 mpg UK combined. Real-world mixed driving typically yields 48–55 mpg (UK), depending on condition and driving style.
Yes. The XUD11BTE is an interference design. If the timing belt fails, pistons will contact open valves, causing severe internal damage. This makes strict adherence to the 120,000 km or 5-year belt replacement interval absolutely critical.
Peugeot specifies a 10W‑40 mineral or semi-synthetic oil meeting ACEA B3/B4 standards. Always avoid low-SAPS or Longlife oils. Change every 10,000 km to protect the turbo and maintain injection pump longevity.
