Requirements
(CALIFORNIA ONLY)
Additional Information

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 error in the transmission control unit in affected DSG transmissions,
certain fault codes that turn on the malfunction indicator lamp (MIL) cannot be cleared after
completion of repairs to resolve the underlying problem with the transmission that turned
on the MIL. This issue does not impact tailpipe emissions or vehicle drivability. Stored faults
may prevent the vehicle from passing subsequent state inspection and maintenance
testing.
Update transmission control module (TCM) software.
On or about April 26, 2024, the campaign code will be applied to affected vehicles.
Owner notification will take place in May 2024. An owner letter example is included in this
bulletin for your reference.
The California Air Resources Board and the Department of Motor Vehicles (DMV) require
emissions-related campaigns to be completed prior to vehicle registration renewal. When
campaign work is done you must provide the owner with a signed “Vehicle Emission Recall –
Proof of Correction” certificate (RC EMISCAVWAU). Order certificates online via the
Compliance Label Ordering portal at www.accessaudi.com.
Please alert everyone in your dealership about this action, including Sales, Service, Parts
and Accounting personnel. Contact Warranty if you have any questions.

Customer Letter Example (USA)




This notice applies to your vehicle:   , 
Subject : Emissions Recall 37P3 – Transmission Control Module (TCM) Software
Dear Audi Owner,
In cooperation with the California Air Resources Board, we are informing you of our decision to conduct an emissions recall on certain
2023 model year Audi vehicles. Our records show that you are the owner of a vehicle affected by this action.
What is the issue?
Due to a software error in the transmission control unit in affected DSG transmissions, certain fault codes that turn on the malfunction
indicator lamp (MIL) cannot be cleared after completion of repairs to resolve the underlying problem with the transmission that turned
on the MIL. This issue does not impact tailpipe emissions or vehicle drivability. Stored faults may prevent the vehicle from passing
subsequent state inspection and maintenance testing.
What will we do?
Your authorized Audi dealer will update the transmission control module (TCM) software in your vehicle. This work will take about an
hour to complete and will be performed for you free of charge. Please keep in mind that your dealer may need additional time for the
preparation of the work, as well as to accommodate their daily workshop schedule.
IMPORTANT! Please note that if any control module(s) in your vehicle has been “chipped,” “tuned,” or otherwise modified
from factory specifications with aftermarket components and/or software, work needed to repair, replace, or return the
control module(s) to factory specifications is NOT covered under this action.
What should you do?
In order to limit any possible inconvenience, please contact your authorized Audi dealer as soon as possible to schedule this work. 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.

Section B – Transmission Control Module Software Update
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 “Current ODIS Service Version” circular found in Elsa2Go Service References.
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 Wi-Fi 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.
NOTE
•
All campaign software updates must be completed during a single, standalone ODIS Diagnostic Session.
You must fully complete this campaign and send all logs before beginning any other campaigns or
operations.
•
If there are any ODIS “Hot-Fix” patches installed, they must be removed from the scan tool before beginning
this operation. ODIS “Hot-Fix” patches may affect the update process.
WARNING
Radiator Fan(s) may cycle ON high speed during the Update Process! There is a serious risk that personal injury
may result if contact is made with spinning fan blades. Keep hands and all objects away from Radiator Fan(s) during
Update Process!
