Service
Note:
This software update procedure may only be claimed once per applicable VIN. Additional software update
attempts will not be covered.
Software Update Procedure
Note:
Prior to launching VAS Diagnostic Device application and starting control module update process, confirm tester
screen saver and power settings in accordance with Special Tools and Equipment - Service Information Circular #
VSE-08-18. Failure to do so may result in the tester entering power save mode during data transfer, and
subsequent control module failure.
When using any tester in conjunction with a VAS 5054A wireless transmitter head for a flash procedure, please
connect a USB cable between the transmitter head and the tester. Failure to do so may lead to errors during the
flash procedure. Also, ensure that the tester is not communicating via Bluetooth as the Bluetooth protocol
is not a robust data transfer environment for the flash process. Control module failures caused by
flashing via Bluetooth will not be covered.
Note:
All Volkswagen scan tool devices must only be used with their power adapters plugged in. Under no
circumstances should they be used on battery power alone during the programming procedure.
Critical Warning: The Midtronics Battery Charger must be connected to the vehicle battery for the duration of the
programming, to ensure the battery state of charge remains above 12.5 volts during the update process. If the
battery drops below 12.5 volts, the programming could fail which may result in damage to the control module.
Control modules damaged by insufficient voltage will not be covered.
The technician should verify the vehicle voltage prior to starting the update process, and should monitor the
voltage for the duration of the update.
• Connect the VAS Diagnostic Device to the online network.
• Connect the VAS Diagnostic Device to the vehicle and switch ON the ignition.
• Switch OFF Bluetooth on the tester.
• Connect the USB cable between the VAS5054A transmitter head and the tester.
• Launch ODIS application, select “Diagnosis”, select “Start Diagnosis” and identify the vehicle.
• After the control units are identified, select the “Special Functions” tab.
