S oftw ar e update
General information before the software update is conducted:
• The closed-circuit voltage of the vehicle must be at least 12.5 V during the update. Connect a suitable battery charger to the vehicle. For
further information refer to the Repair manual.
• During the update switch off all unnecessary consumers (ventilation, seat heater, interior illumination etc).
• Because of the highest transmission stability we recommend the use of the diagnosis interface VAS 6154 (WiFi diagnostic tool) only in the USB
operation or the cable-connected VAS 5055 for the reprogramming (updating) of control units. If these units are not available, the diagnosis
interface VAS 5054 (A) can also be used in USB mode.
