Got the 8.561.6067 error when I wanted to change some things in variant coding for my smart 450. Tried some methods and then solved in the end. Just post for sharing.
Ps. Tool i used: sdconnect compact 4 software 07/2012
Note: Unlock the ECU first!
Perform unlock (F3)
After this the variant coding can be saved without the error, I can save every setting i want.
Maybe it is a similar thing for other MB models…
