Hey there,
You can usually get the MDU software through official Miele service channels as it is not publicly available for general download. It is primarily meant for certified technicians, and unauthorized sharing might violate their licensing terms.
However, if you are an authorized service partner or technician, I recommend contacting your local Miele service representative or regional technical support they will provide the correct version along with any required hardware interface or activation process.
If you are just trying to troubleshoot a Miele appliance let me know what model or issue you are dealing with sometimes you do not even need the full diagnostic tool to figure things out. Happy to help further.
