Hi,

Here is the info you need:

When on the main screen click on "Units" on the top of the screen
Then click on "LCM"
Then click on "Coding Data"
Then click on "Check/Control Messages"
Now you will be in a menu to check/uncheck which error messages you want to appear on the dash.
Just uncheck the "SELFLEVEL SUPS.INACT" box then click on "Write" at the bottom right of the screen and thats it done!
Now just exit the software as normal and fire the car up and the error message on the dash will be non existant :-)

Hope this helps and let me know how you get on.

Cheers,

Raj
