See owner's manual" (see picture in attachment). Attachments File Description picture limitedservices.JPG Picture: Limited service message in instrument cluster Cause: This is a status message. It appears whenever a diagnostic unit, e.g. XENTRY Diagnostics or a third-party adapter from the free accessories trade, is connected to the on-board diagnosis (OBD) interface, triggering diagnostic queries on the diagnostics CAN. The message informs the driver that in this state the Mercedes me connect basic services, such as maintenance management, telediagnosis and other services, no longer function or function only to a limited extent. In addition, the vehicle owner's manual provides information about further possible vehicle problems under "General information" and the heading "Diagnostics connection". When the diagnostic unit or the third-party adapter is removed and the bus is idle, the message no longer appears. NOTE: In some cases, third-party adapters may also be connected in series with the OBD socket behind the paneling (see picture in attachment). In seldom instances a third-party hardware is detected, although none is installed in the vehicle. There is no impairment to the vehicle function with one-time detection. In this case, the message is no longer shown after bus idle (ignition off, vehicle locked for approx. 30 minutes).

Remedy: Check whether a third-party adapter is being used in the vehicle (visual inspection of OBD interface/ ask the customer if necessary). In fleet vehicles it is quite normal for a third-party adapter to be installed (e.g. insurance requirements, fleet management etc.) If a third-party adapter is being used in the vehicle, explain the reason for the message to the customer.
