CAUTION
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!

CAUTION
The rear wiper may activate during the software update.
– Ensure that the rear window is free of any obstructions.

CAUTION
Make sure to switch to gear P when working on the vehicle. When working on the vehicle (for example,
when updating software or replacing control units) the vehicle functions may be influenced until the work is
fully completed. This can, for example, mean that the vehicle may not secure itself against rolling if it is left
unattended:
– Therefore, the vehicle must always be parked in P.
– Also actively check before and after faults, breaks or work interruptions that P is selected.
– If a vehicle with rolling capability is needed as part of the work, make absolutely sure that an active
gear is not selected – instead shift to N.

NOTICE
If the customer is enrolled in Car-Net and they have the myVW app downloaded on their phone, they may
receive several notifications during the update process.

1. Document the technical bulletin requiring this update
•

Clearly note on the repair order the technical bulletin number that directed to perform this software
update.

2. Review prerequisites and perform preliminary work
•

•

Prepare the VAS 6150X diagnostic tester (ODIS tester) for use:
‒

Check that the ODIS tester is updated to the latest version. See: Elsa2Go > Infomedia > Current
ODIS Service Version

‒

Ensure the ODIS tester remains powered from its AC power supply adapter for the duration of
the software update. The ODIS tester must not be operated from its internal battery power only.
The tester will shut down when battery power is low, which could result in control unit damage.

‒

Verify that ODIS tester screen saver and power saving settings must remain off. Failure to do so
may result in the tester entering power save mode during the software update, which could result
in control unit damage.

‒

Use only a USB hardwire connection between the VAS 6154A or VAS 6154B diagnostic
interface and the ODIS tester. Performing a software update using a Bluetooth or WiFi
connection to the diagnostic interface increases the risk of a lost connection, which could result
in control unit damage. It also increases the time required to perform the update. Requests for
additional labor time or coverage of a damaged control unit will be denied if the GFF log shows
the update was performed using a Bluetooth or WiFi connection to the diagnostic interface.

Prepare the 12V battery charger VAS 5908 for use:
‒

Before starting programming, it is essential to perform the following actions for the VAS 5908
battery charger. By default, the charger will switch-off automatically after a period of time. To
prevent this, the following must be carried out: Switch it OFF and then ON again each time the
charger is connected. The battery charger’s display must have switched off before it’s restarted.
The charging time can be changed in the charger’s settings menu (access code = 6161). Refer
to the owner’s manual for further information. Do not change any other settings that may damage
the charger or the vehicle.

‒

When connecting the charger to the battery, connect the positive cable to the positive charging
terminal for the battery and connect the negative cable to the grounding lug on the vehicle body.
Never connect the ground cable directly to the negative terminal of the 12V battery.

‒

The 12V battery charger VAS 5908 must remain connected and powered-on for the duration of
the software update, so that the 12V battery remains 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 control unit
damage.

•

Before starting the software update, ensure the following conditions are met:
‒

The Windows operating system power options must be set according to the ODIS tester setup
directions. See: Elsa2Go > Infomedia > Service references > VHW-22-13 Change Power
Options in Windows® 10 (or latest communication). The “Device Power Management” sections
from the VAS 6150X Diagnostic Laptop – Unpacking and Setup Instructions can also be
referenced.

‒

The dealership’s D3 Edge Box must be installed and configured correctly. See: Elsa2Go >
Infomedia > Service references > D3 Edge Box server Installation and Troubleshooting Guide;
D3 Edgebox User Guide; VHW-25-04 D3 Edgebox Host Name Requirements; VHW-25-03
Revised D3 Edgebox Firewall Requirements – Outbound; VOS-25-70 Most Common Reasons a
D3 Edgebox Isn’t Working; and VOS-25-52 D3 Edgebox Hardware Operation.

‒

The ODIS settings must allow for sending feedback support requests. See: Elsa2Go > Infomedia
> Service references > VOS-25-51 New ODIS Support Feedback Procedure and VOS-25-57
ODIS Support Feedback Important Details (or latest communication).

‒

The ODIS user must have access to Group Retail Portal (GRP). See: Elsa2Go > Infomedia >
Service references > VOS-24-35 ODIS log in Procedure for Group Retail Portal (GRP) and VOS25-78 Group Retail Portal GRP FAQs (or latest communication).

‒

The dealership’s internet firewall settings must meet the specified requirements. See: Elsa2Go >
Infomedia > Service references > VHW-25-02 VAS Diagnostic Device Firewall Settings and
VHW-25-03 Revised D3 Edgebox Firewall Requirements – Outbound (or latest communication).

‒

The ODIS tester must have port 8080 enabled for incoming TCP connections. Please contact
your local IT administrator as needed. If there are any support-related queries, please contact
ODIS service support. The relevant firewall settings can be found in the table below. See:

•

Verify that only one vehicle key is present in the vehicle for the duration of the software update.

‒

The vehicle key battery must be OK before starting the software update.

‒

Any additional keys must be a minimum of 20 meters away from the vehicle.

•

Verify the vehicle is not connected to an HV battery charge station for the duration of the software
update.

•

Check for any pre-existing vehicle faults:

•

‒

Any diagnostic trouble codes (DTCs) that specifically indicate “control unit faulty” must be
resolved before starting the software update. Otherwise, the update may stop at the affected
control unit and fail to proceed.

‒

Diagnosis and repair of pre-existing conditions are not covered under this technical bulletin.

If the work steps must be interrupted for any reason, stop at one of the bus-sleep steps.

3. Perform 12V battery check

In the “Test plan” tab, start the “Perform 12V battery check” test program with the “Perform test” button.

•

Follow the instructions in the test program:
‒

If the test result “12V battery is OK” is returned, continue with “4. Document vehicle settings”.

‒

If the test result “12V battery is faulty – replace!” is returned, the 12V battery must be replaced.
Note, if necessary, replacement of the 12V battery is outside the scope of this technical bulletin.

‒

Then continue with "4. Document vehicle settings”. Note, the battery adaptation does not take
place until “10. Adapt 12V battery”.

4. Document vehicle settings
A “factory reset” of the ICAS1 is necessary during the update. This resets the customer settings and vehicle
settings.
NOTICE
To ensure the software compound update does not cause customer dissatisfaction or customer
complaints, the vehicle settings must be documented at this point (photographed) and restored under “15.
Restore customer settings”.
Select and document the vehicle settings in the infotainment system under the “Settings” tile (recommended
via photos).
Then continue with “5. Update information electronics (ICAS3)”.

5. Update information electronics (ICAS3)
In the measure described below the information electronics (ICAS3/diagnostic addresses 005F and 8125) is
updated to SW3748.
The information electronics (ICAS3/diagnostic addresses 005F and 8125) must be updated as follows.

5.1 Prepare USB stick for the software update of the infotainment system
The software must be downloaded via the Flash Media Creator (FMC). See: Elsa2Go > Infomedia > Service
references > VOS-25-58 Flash Media Creator (FMC) for D3 Edgebox (Replaces SD Creator)
•

•

A commercially available USB stick is required. The USB stick is servicing material, and the cost of the
USB stick will not be reimbursed. The USB stick can be reused for multiple software updates.
‒

Use only a 32GB stick for this update – a USB stick of higher capacity cannot be used.

‒

The vehicle infotainment uses a USB-C connector. If the software is downloaded onto a USB-A
stick, a single device USB-C adapter will be required (a USB hub is not allowed).

‒

USB type C (at least USB 2.0), reading/writing speed: at least 40 MB/s / 10 MB/s.

‒

USB type A including type C (at least USB 2.0), reading/writing speed: at least 40 MB/s / 10 MB
/s.

‒

USB type A with adapter to USB type C possible (at least USB 2.0), reading/writing speed: at
least 40 MB/s / 10 MB/s.

Before it is used, label the USB stick with the respective part number from the following table:

ID.S version

Software part number to create USB stick

5.4.3KD

3G8.919.360.DC

NOTICE
If the search for the software part number returns no result, check if the certificate is valid.
– In the FMC software settings, select the valid certificate used with ODIS.

NOTICE
As a best practice, the USB drive should be recreated on a regular basis from the Flash Media Creator
(FMC) to avoid file corruption which can lead to USB update errors.
– Do not use files saved locally to the PC or copy a USB stick that you have made. Only use the Flash
Media Creator (FMC) to make the USB stick. The Flash Media Creator (FMC) checks whether the USB
stick is correct. Software updates with a copied USB stick can damage the device if the software
update is interrupted. Any device damaged by an interrupted software update caused by an improperly
made USB stick cannot be claimed under warranty.

– Do not use a USB hub (USB distributor to use several USB devices on one USB port) to install the
software update.
