Function sequence for workshop level settings in general
The workshop level is used by the technician in the workshop for reading out vehicle and service data and provides assistance with carrying out the service.
The "Workshop level" menu is activated as follows:
- Select "Trip" menu
- Press Accept phone call button on Accept and end phone call button (S111s3) and then the n/ (S110s6) at the same time for t > 3 s.
The display in the multifunction display (A1p13) changes to the workshop level. By pressing the scroll forward/back button (S110s1) in the left multifunction steering wheel button group (S110), it is possible to change between the respective menus and submenus or to scroll through various lists. Selection is then made by pressing the OK button.
The steering wheel electronics (N135) read in the control interventions at the multifunction steering wheel button groups directly and send them via the steering LIN (LIN E1) to the steering column tube module control unit (N80).
The steering column tube module control unit forwards them via the chassis CAN to the instrument cluster.
The following menus are accessible:

- Vehicle data (e.g. chassis number)

Dynamometer test mode menu
Activating the dynamometer test mode prevents faults being entered in the Electronic Stability Program control unit (N30/4) during the brake test on the roller dynamometer.
It is possible to switch between the following settings in the Roller dynamometer mode menu using the left multifunction steering wheel button group:
- "ESP On"
