PJ: is the engine family, in this case 1106D-E66TA 12345: is the engine build type number or engine order reference U: is the country of manufacture, in this case UK 123456: is the unique engine number P: is the year of manufacture

In the example above, engine is an 1106D-E66TA engine with a turbocharger

  • 1106 is a 1.1L displacement per cylinder and six cylinders
  • D signifies that this engine is suitable for EU Stage III / U.S. EPA Tier 3 equivalent emissions standards
  • E identifies the engine has an electronic management system
  • 66 confirms the engine has a total displacement of 6.6 litres
  • TA means the engine has a turbocharger and is air-to-air charge cooled

 What do I need to enter in the search?

The minimum requirement to produce a result in the engine serial number search tool is the initial build list element, (2 to 4 letters followed by 4 or 5 numbers). Including the full entry of 15 or more digits will deliver the best results.

 Guidelines

  • Do not enter spaces or symbols such as asterisks as the number will not be recognised.
  • Clean and check the plate carefully, as letters and numbers may look the same.
  • Capital letters are not required, the system recognises both lower- and upper-case letters.
