MB SD Connect Compact 4 support reading out & erasing trouble code,reading the real-time data of sensor and actuator, coding and programming. Also support wireless diagnose, support K line,CAN BUS and UDS protocol, with multi-language,Support Mercedes Benz Cars :1995-~.

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

SOLVED now!

Note: Unlock the ECU first!

1. Go to the developer menu in SAM (last item)

2. Enter “Actuations”

3. Choose “Complete index”

4. Scroll all the way down and choose SG_Entriegelung (=control unit unlock)

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...
