Information
If the messages "Service now", "Intermediate maintenance now" and/or "Oil service now" are
displayed on the multi-function display although the mileage and date for the next service have not
yet been reached (implausible service reminder indicator display), the service interval must be reset
using the PIWIS Tester so that the messages will no longer be displayed in the instrument cluster.
In this case, carry out the steps described in the next section  Technical Information 'WE0200
Resetting service reminder indicator and re-writing service interval'.
If this is not the case, continue with the section  Technical Information 'WE0200 Subsequent
work'.

Resetting service reminder indicator and re-writing service interval
Information
If the service intervals are reset without first carrying out maintenance, intermediate maintenance or an
oil service, the original values for the date and mileage of the last service events that are stored in the
instrument cluster must then be restored. This ensures that future service intervals will be calculated
correctly.
For this reason, the currently stored values for the date and mileage of the last service events must first
be read out of the instrument cluster and noted.
