Diagnosis
Diagnosis is available for fault repairs and service procedures using the DISplus/GT1.
The test plan for the VGSG contains valuable information on:
• Replacing control unit
• Replacing transfer case
• Transferring adaptation values
- Automatic
- Manual
• Reading out adaptation values
Programming (flashing)
Both the transfer case control unit (VTG) and the DSC control unit are programmable and
the new control unit(s) must be programmed when replaced. The wear values stored in
the VTG control module (to be replaced) must be transferred to the replacement VTG.
Warning Indicator Lamps
The warning indicator lamps for the xDrive / DSC are found in the instrument cluster as
shown on the bottom of this page.
The warning indicator lamps and acoustic signals (gong) are assigned to the xDrive / DSC
system states of malfunction described on the next two pages.
