Technical Service Bulletin
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.

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 unit 1, J794 (address word 5F). 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 unit 1, J794
(address word 5F) 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.
Coding change A3 cabriolet with MIB High: Byte 24 of the information control unit 1, J794 (address word 5F)
long coding controls the activation of the VR/SDS system.

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.

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.
