Peugeot 406 Engines for Sale | Engine Finders

Engine Finders connects UK drivers with specialists for reliable, reconditioned Peugeot 406 replacement engines. Whether battling XUD9 diesel injection pump failures across early 406 diesels or TU-series petrol head gasket issues in later variants, we provide direct OEM-spec solutions.

Peugeot 406 Replacement Engines

The Peugeot 406 evolved through two critical generations: the original 1995-2004 series with XUD9 diesel and TU petrol engines, followed by 2004-2009 updates with DW-series diesels and enhanced TU petrol variants. All XUD9 diesels (1995-2004) suffered injection pump failures addressed in Technical Service Bulletins, while TU-series petrol engines share head gasket vulnerabilities regardless of displacement (1.6L-2.0L). The later DW-series diesels introduced common rail injection but inherited cooling system weaknesses from predecessors, affecting all 406 variants equally across saloon, estate, and coupé body styles.

Peugeot 406 Models & Engines Codes

The 406 series utilized distinct engine families across both generations, with specific codes indicating shared components and common failure points that affect all variants within each family.

  • XUD9: 2.1L diesel (1995-2004) - Injection pump (9624320780) failure across all 406 variants
  • TU3/TU5: 1.6L-2.0L petrol (1995-2009) - Head gasket (162018518R) failure in all power outputs
  • DW10: 2.0L diesel (2004-2009) - EGR valve (9634279680) clogging in all late-406 models
  • DW12: 2.2L diesel (2004-2009) - High-pressure pump (9634279780) failures across all variants
  • TU3JP: 1.9L petrol (1995-2004) - Timing belt (162018498R) issues affecting all early 406 models

These engine families were used across all 406 body styles including saloon, break (estate), and coupé variants, meaning failure patterns and replacement requirements remain consistent regardless of body type.

Buy Used and Second-Hand Peugeot 406 Engines

For 406 owners: Used engines carry high risk due to shared XUD9/DW-series failure patterns. Reconditioned units with updated injection components (9624320780) are essential for pre-2004 diesels. Remanufactured TU-series engines with upgraded head gaskets (162018518R) are recommended for all petrol variants regardless of displacement.

  • Reconditioned XUD9 engines with updated injection pumps and timing components
  • Remanufactured TU-series petrol engines with reinforced head gaskets
  • Overhauled DW-series diesels with enhanced cooling system components
  • Complete engine assemblies with all necessary mounting hardware

All engines undergo comprehensive inspection and testing to ensure compatibility with your specific 406 variant and meet original Peugeot specifications.
