Information for the customer after the software update:
Various settings must be re-adjusted after the software update. For this reason, a customer letter has been

attached to this TSB. Please print this document and give it to the customer when returning the vehicle.
Applies to vehicles with high-voltage components:
To prevent the high-voltage battery from charging during the software update, the high-voltage charging cable on

vehicles with high-voltage components must be unplugged BEFORE the SVM code is entered.
Please note that charging the high-voltage battery during a software update can cause damage to the high-voltage

components.
Technical Background

Not applicable.
Production Solution
Implemented from week 34 onwards (depending on model).
Service
Please read the following information carefully.
The total time required for the combined software update (including preparations and subsequent work) is

approximately 3.5 hours.
There are different procedures for the software update for PPE and PPC models.
Prerequisites for flashing:
* — The driver’s door must remain open for the duration of the flashing procedure. Please do not run the

diagnostic interface cable through the window because the window regulators will be initialized in a later step.
* Please activate privacy mode (mobile data off).

* Please switch off the background lighting in the HMI to prevent negative interference.
* Please only place one vehicle key inside the vehicle. The key must be placed on the hazard warning lights

switch in the Audi Q6 e-tron and Audi A6 e-tron (PPE) and on the reader coil in the Audi A5, Audi Q5 and Audi

AG (PPC).
* Before entering each code, check whether the current date/time is displayed in the vehicle. If not, move the

vehicle to a location where there is GPS reception, or set the date and time manually. Otherwise, an update

will not be possible, or it will be aborted.
* No additional/other work may be performed on the vehicle for the entire duration of the update.
* The firewall settings which correspond to the latest release notes of the current ODIS version at Elsa2Go>>

Service References>>Vehicle Diagnostics always apply.
©
The vehicle must be put in bus sleep mode before the function “SVM — Authorized Multiple Code

Entry” is run. Please start the update after a bus sleep.
Prepare vehicle for flashing:
* Put the vehicle in bus sleep mode (5 minutes).

* Connect battery charger unit in accordance with specifications in “Standards for workshop equipment”.

* Switch off electrical equipment (blower, seat heater, lights, etc.).

* Move selector lever to P.
* Connect the diagnostic tester to the vehicle using a USB cable (with door open and window closed).
* The driver’s door must remain open for the duration of the flashing procedure. Please do not run the

diagnostic interface cable through the window because the window regulators will be initialized in a later

step.
A diagnostic tester with the following Audi brand version or higher is required: 2.39.4
©
We strongly recommend flashing using a USB cable. This ensures that data transmission is as reliable

as possible.
Infrastructure mode is not permissible as it is very prone to interference/errors.
For the Q6 e-tron and all later Audi models, you must ensure that port 8080 on your diagnostic device is

enabled for incoming TCP connections.
Please contact your local IT administrator regarding anything above.
If you have any support-related queries, please contact ODIS service support.
Performing software update
©
If flashing is aborted, error messages are shown or messages are shown in the instrument cluster during

the software update, please refer to the separate TSB 2079692 00 Aid for TSB 2079690 (00 Combined

software update 03.10.00/C (28.13.01) KD2).
Procedure to begin flashing:

« Select “flash”.

* Select “SVM — Authorized Multiple Code Entry’.
*« Perform the software update using the function “SVM — Authorized Multiple Code Entry” and the following

SVM codes:
« PPE SVM Code (Q6 e-tron, Q6 e-tron Sportback, A6 e-tron Sportback):

BLKD2PPE, DUCLDRM0046,DUCDOORWR

AL
After the function “SVM — Authorized Multiple Code Entry” is run, the vehicle is identified, the data is calculated in

the backend and then transmitted to the vehicle, and the update phase starts in the vehicle.
* When the update phase starts, a message will prompt you to unplug the diagnostic interface (optional).
Unplugging the diagnostic interface and vehicle diagnostic tester during the update phase is possible. The vehicle

diagnostic tester indicates when the diagnostic interface can be unplugged.
Further information on how to proceed is displayed on the vehicle diagnostic tester.
©
You can track the progress of the update on the display in the vehicle. Information on the progress is also

displayed on the vehicle diagnostic tester. For this software update, the progress may not be displayed in

the vehicle during the first 20 to 30 minutes. The display in the vehicle switches on and off multiple times
and remains switched off (is dark) for several minutes. A reliable indication of the progress is only shown
after 20 to 30 minutes. You must not perform any actions on the vehicle during this time (e.g. switch the

ignition on/off, select a gear).
You are permitted work on other customer vehicles during the update phase if the diagnostic interface has

been unplugged.
Procedure if diagnostic interface has been unplugged:
* The diagnostic interface must not be plugged back in while the software update is running!
* — The following message in the vehicle indicates that the update was successful: “Instal/ update finished

successful”.
* — The following message in the vehicle indicates that the update was not successful: “Installation error”.
« — In both cases, the function “SVM — Authorized Multiple Code Entry” must be run again to ensure successful

feedback documentation or, if flashing was aborted, to receive further instructions.
* To do this, plug the vehicle diagnostic tester back in and run the function “SVM — Authorized Multiple Code

Entry’.
Procedure after flashing:
*« Once the function “SVM — Authorized Multiple Code Entry’ is finished (special functions display), unplug the

vehicle diagnostic tester from the vehicle
¢ After the update, it is very important to open and close all vehicle doors once (adaptive cruise assist
