Emissions Service Action 24EF
Undisclosed Engine and/or Transmission Control Module Software
Dear Volkswagen Owner,
In cooperation with the United States Environmental Protection Agency and the California Air Resources Board, we are informing
you of our decision to conduct an emissions service action on certain 2012-2017 model year Volkswagen vehicles. Our records
show that you are the owner of a vehicle affected by this action.
What is the issue?
Engine and/or transmission control module software designed and certified for similar
models/model years was used in vehicles affected by this emissions service action. It is
undetermined whether there could be an impact to on-board diagnostics (OBD) or CO2
emissions. As a precautionary measure, Volkswagen is proactively updating the software
calibrations on affected vehicles.
What will we do?
Your authorized Volkswagen dealer will update the engine control module software and/or
transmission control module software. This work will take about one 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 repair, as well as to accommodate their daily workshop schedule.
IMPORTANT! Please note that if the ECM or TCM in your vehicle has been “chipped,”
“tuned,” or otherwise modified from original factory specifications with aftermarket
components and/or software, work needed to repair, replace, or return the module to
original factory specifications is NOT covered under this action.
What should you do?
Please contact your authorized Volkswagen dealer as soon as possible to schedule this service.
To set up an appointment online, please visit www.vw.com/find-a-dealer.
Lease vehicles and
address changes
If you are the lessor and registered owner of the vehicle identified in this action, please forward

Section B – Repair Procedure
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.
If using a Bluetooth transmitter head, it is connected to the tester with a USB cable.

Performing a software update using a Bluetooth 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.
The Bluetooth function of the scan tool is physically switched off .
