Have you done it? Could you give more detail ?. I have identified these SSU module strings in the mx5:
731-01-01 5030 C824 21C7
731-01-02 180D 1926 902F
In the Cx5 the start-stop can be cancelled by editing 2 of the bytes of these strings, but don't know about the mx5...
I have read these instructions here (2nd post):
Wischerwasserbehälter vergrößern und Niedrigstandanzeige aktivieren
It explains how to change bits.
The actual Excel file is available here:
