In order to correctly perform a DEF/Urea/SCR/AdBlue delete on a Claas Jaguar | Lexion | Tucano | Xerion machine it is necessary to read both the MCM (Motor control Module) and ACM (Aftertreatment control Module).


  • When you have read the Software from both the MCM and ACM you put them in a .zip or .rar folder.
  • Upload the .zip or .rar containing both files on Tuning24.org.
  • We then modify the software from both control Modules.
  • After you receive them back you have to write both modified software solutions.
  • You can then disconnect the DEF/Urea/SCR/AdBlue pump like shown in the photo.

Please note that the ACM (Aftertreatment control Module) does need to stay connected.
