6. Warnings and error messages
In the event of a malfunction, the control unit display will show a visual error indication
on the left-hand side and an error code on the right-hand side (code M52 in the accom-
panying example).
As in some other areas, just switching the control unit off and on again can sometimes
resolve the displayed error.
The following table lists the error codes that are generally easy to resolve. If the specified
remedy does not resolve the problem and the error code continues to be displayed, please
contact your specialist dealer.
If an error appears in the control panel display that is not included in the following table,
please also contact your specialist dealer.
