

ELSA is the only valid inquiry/verification source. Check ELSA on the day this vehicle UPDATE will be
performed to verify vehicle eligibility for the UPDATE. Status must show “open”. Attach an ELSA printout
showing the “open” status to the repair order.



If this UPDATE appears to have already been performed but the code still shows open in ELSA, contact
Warranty before proceeding further. Another dealer may have recently performed this UPDATE but not
yet entered a claim for it in the system.



ELSA may also show additional open action(s); if so, inform your customer - this work can be done while
the vehicle is in for this UPDATE.



Contact the Warranty Helpline (U.S.) or the Warranty Campaign Specialist (Canada) if you have any
questions.



Enter the VIN in ELSA and proceed to the
“Campaign/Action” screen.

TIP
On the date of repair, print this screen and keep a
copy with the repair order.


Confirm the Campaign/Action is open . If the status is closed, no further work is
required.



Note the Applicable Criteria ID for
use in determining the correct work to be done
and corresponding parts associated.

94o7 UPDATE
Software Update for Driver Assist Systems Control Unit
(NVLW)

SVM Update Instructions
NOTE
Prior to launching the VAS Diagnostic Tester and starting an update, ensure the following conditions are met;
The ODIS software is completely up to date.


Refer to the “Alerts” section on ServiceNet home page for the current ODIS version.

The battery charger is connected to the vehicle battery and remains connected for the duration of the
software update.


Battery voltage must remain above 12.5 volts for the duration of the software update. Failure to
do so may cause the update to fail, which could result in damage to the control module. Control
modules damaged by insufficient voltage will not be covered.

The screen saver and power saving settings are off.


Failure to do so may result in the tester entering power save mode during the software update,
which could result in damage to the control module.

The VAS Diagnostic Tester is plugged in using the supplied power adapters.


Under no circumstances should the tester be used on battery power alone during the software
update. Failure to do so may result in the tester powering off during the update, which could result
in damage to the control module.

Flash process through “Audi Flashing” not Guided Fault Finding (GFF).


DO NOT USE Guided Fault Finding (GFF) to perform this flash. Using GFF will cause the flash
to take longer. Requests for additional time will not be considered.

The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable.


Performing a software update using a Bluetooth or WiFi connection increases the risk of losing
connection during the update, which could result in damage to the control module.
It also greatly increases the time required to perform the update. Requests for additional time or
parts will be denied if the GFF log shows the update was performed using Bluetooth or WiFi.

TIP
As a best practice, customer presets should be documented prior to performing any update in the event these
settings are lost during the update.
