One of the following conditions is present:
 The message “Talk button for speech dialog system not
used” appears in the DIS (driver information system) for A3
Cabriolet vehicles (Figure 1).
 The message “Not available” appears in the DIS for A5
Cabriolet vehicles (Figure 2).

Technical Background
By design, the voice recognition (VR) system (also known as the speech dialog system (SDS)) is not enabled by
the factory for A3 Cabriolet and A5 Cabriolet vehicles due to potential performance issues. R8 Spyder and 3rd
Generation TT Roadster are not affected because these vehicles use seatbelt microphones to improve VR/SDS
performance.
Production Solution
Not applicable.
Service
If the customer requests to have the VR feature enabled, it can be done through a change to the coding of the
information control module 1, J794 (address word 005F). The labor to perform this change is not covered by
warranty.
Because the coding of the MMI main unit is automatically checked with SVM, any subsequent SVM
communication could potentially undo this manual coding change. This information should be communicated to
the customer so that he or she understands that this change may be unintentionally undone at the next service
visit. For this reason, it is good practice to document this and any other modifications in the dealership customer
database for future reference.
Coding change for A5 Cabriolet vehicles with MMI3G/MMI3G+: Byte 16 of the information control module 1,
J794 (address word 005F) long coding controls the activation of the VR/SDS system. Note that this is byte 16
when counting in decimal, i.e., 1, 2, 3,...9, 10, 11, 12, 13, 14, 15, 16. Some aftermarket diagnostic tools number
the coding bytes using HEX, i.e., 1, 2, 3,…9, A, B, C, D, E, F, 10, 11.
Note:
Aftermarket scan tools may follow different labeling nomenclature for the bit information and should not be used
for this task. Incorrect changes can lead to undesirable or failed operation.
Coding change A3 Cabriolet (MY2015-2016) with MIB1 High & (MY2017) with MIB2 High: Byte 24 of the
information control module 1, J794 (address word 005F) long coding controls the activation of the VR/SDS
system. Additionally, you can use the free text search in ODIS to search for “Speech” or “SDS” and select “SDS
activated” within the coding function.
1. Start diagnosis with ODIS. Uncheck “Guided Fault Finding” to speed up the process, or use OBD (selfdiagnosis) from the ODIS start screen. The instructions in this TSB will be from GFF.

2. Right-click 5F*. Choose “Identify Control Module”.
Next, right-click 5F again and choose “Select
version”. Then, right-click 5F again and choose
“Control module OBD”, then select “Code” (Figure
3).
*For tablet VAS testers, long-press the screen for
the additional control module options.
Figure 3. ODIS Options for 5F.
3. For MMI3G/MMI3G+: Scroll down to byte 16 and select it.
For MIB High: Scroll down to byte 24 (which should be the last option) and select it.
4. At the bottom of the screen, choose “Binary
Coding”. The Binary coding input window will
appear (Figure 4).
Figure 4. ODIS binary input for coding with indicated bit
positions.
5. For MMI3G/MMI3G+: Change bit 0 from “1” to “0”. Bit position 0 is indicated in Figure 4.
For MIB High: Change bit 1 from “0” to “1”. Bit position 1 is indicated in Figure 4.

Note:
When counting positions with binary, start on the far right and count toward the left. The first bit position is
called “bit 0” and the second position from the right is “bit 1” (Figure 5). Do not alter any other bit positions, as
doing so can affect Wi-Fi, navigation, and other features. If other bits are accidentally changed and the
original coding is not known, run an SVM check module configuration or spec/actual to reset the coding to
factory values, then begin at step 2 again.
Figure 5. Bit 1 (highlighted) shows a value of 1.
6. Hit “Apply” in the pop-up window, then hit “Apply” at the bottom of the main window.
7. Perform a three-finger reset of the main unit using
the MMI control panel (Figure 6-9).

8. Test the system to verify all functionality. If the
VR/SDS system does not fully function, or if it is in
a different language, go to Menu >> Setup MMI >>
Language (Figure 8) and change the language to
any language other than English (either Spanish or
French). Perform a three-finger reset, then set the
language back to English and test the system
again.

9. Explain to the customer the system limitations and why the feature was disabled by the factory. Any future
customer concerns relating to the VR/SDS system should not be covered under warranty.
