One user of mb sdc4 tried to activate Xentry and need to open “configAssist”, got problem with it ” unable to access service…” So he was unable to go through as the PDF guide on desk, to activate.
obd2tool.com chief engineer solution:
Enter into “Device Manager” to find “Service” then “configAssist “, then click on “Start” and “Ok”. The problem will be solved.
Good luck!
