control and on-board diagnostics (OBD) software: (1) It will correct an issue that is causing the
“check engine” light to falsely illuminate under certain driving conditions, which has resulted in
replacement of the diesel oxidation catalyst (DOC) for certain customers; (2) It will reduce the
likelihood of experiencing an engine shudder that could occur during certain warm-up driving
conditions; and (3) It will improve OBD monitoring of vehicle emissions systems and otherwise
improve the software used by your vehicle.
Update the engine control module (ECM) software calibration.

•
Volkswagen is releasing a software calibration update to the Approved Emissions Modification (AEM). This
software calibration will include the following changes to the vehicles’ emissions control and on-board

If you elect to receive these updates, please contact your authorized Volkswagen dealer as soon as possible to

issue, the dealer can update your vehicle with your written authorization.

Volkswagen dealer for an appointment. The dealer will provide both the AEM and this AEM Correction during the
same appointment with your written authorization.

Section B – Engine 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 “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 .
