Check Campaigns/Actions screen in Elsa on the day of repair to verify that a VIN qualifies for repair under this
action. Elsa is the only valid campaign inquiry & verification source.

Problem Description

Corrective Action
Code Visibility



Campaign status must show “open.”



If Elsa shows other open action(s), inform your customer so that the work can also be completed at
the same time the vehicle is in the workshop for this campaign.

Due to a software configuration issue on Audi vehicles manufactured within a specific period, it
may, in rare cases, not be possible to receive “cell broadcast messages”. A permanent failure
of the emergency call module control unit and communication unit cannot be ruled out as a
result. If this happens, the affected vehicles will not be able to establish an online connection.
Update the emergency call module control unit and communication unit software.
On or about February 22, 2022, the campaign code will be applied to affected vehicles.

Owner Notification

Owner notification will take place in February 2022. An owner letter example is included in this
bulletin for your reference.

Campaign Expiration
Date

date to be eligible for payment. Keep this expiration date in mind when scheduling customers
for this action. If a customer wishes to have this service performed after the expiration date,
your dealerships normal costs associated with this repair will apply.

Subject: Service Action 90T2 - Emergency Call Module Control Unit and Communication Unit Software
Dear Audi Owner,

What is the issue?

period, it may, in rare cases, not be possible to receive “cell broadcast messages”. A
permanent failure of the emergency call module control unit and communication unit
cannot be ruled out as a result. If this happens, the affected vehicles will not be able to
establish an online connection.

What will we do?

Your authorized Audi dealer will update the emergency call module control unit and
communication unit software. This work will take about an hour to complete and will
be performed for you free of charge.

need additional time for the preparation of the repair, as well as to accommodate their
daily workshop schedule. For your convenience, you can also visit www.audiusa.com
and click on the “Find a Dealer” link to locate a dealer near you and schedule this
service.
This service action will be available for you free of charge only until February 22,

costs associated with this repair will apply.
