searches for a contact name in the MMI address book (by using the MMI control knob or the voice recognition
system):
• The MMI screen goes blank then restarts.
• The MMI screen freezes for a few minutes then recovers.

Technical Service Bulletin
Technical Background
This condition occurs because special characters (including symbols,
emoticons, or map icons) are stored in the name field of a phonebook
contact (Figure 1).

Figure 1. Special characters stored in
the name field of a phonebook contact.

Production Solution
Not applicable.

Service
1. All phonebook contact fields (first name, last name, company, phone number, etc.) that have been transferred
to the vehicle must be checked. If special characters are stored in any field, they must be removed. For
additional information, see TSB 2026390, 91 Bluetooth - MMI freezes, streaming music skips, or voice
recognition inoperable due to phonebook.
2. Ask the customer to correct the entries in the phone and to also correct the entries in the source information
from which the entries were obtained. If the phone is synchronized with other smartphone apps, with Outlook,
or with Gmail, changing the information only on the phone may not fix the issue permanently.

Note:
Replacement of the MMI main unit or of the telephone control unit will not fix the condition.

Technical Service Bulletin
For vehicles with MMI3G+:
A troubleshooting MMI script is available for download on the ServiceNet website at ServiceNet >> Technician
References >> Audi MMI Scripts >> MMI3G+ Phonebook Troubleshooting Script.
This script will allow the customer or technician to automatically find invalid entries. If no invalid entries are found,
it can be safely assumed the contacts are not the source of the concern, assuming the max limit has not been
reached.
To use the script:
• Download the script and extract the three files to the root
directory of the SD card. The files are labeled “audicc”,
“copie_scr.sh”, and “graphics” (Figure 2). The script will not
work if the files are not placed in the root directory of the SD
card.
Figure 2. Three files required for the script.
• Allow the MMI system to fully initialize and bond with the customer’s mobile phone.
• Allow the phonebook transfer to complete from the phone to the MMI (the phonebook transfer icon in lower
right hand corner of MMI will disappear), which can take up to 5 minutes depending on the number of contacts
and recent call history logs stored in the phone.
• Insert the SD card into one of the MMI main unit SD card slots. Allow the script to execute (30–60 seconds).
• Once the script completes, a green or red popup
message will appear:
• Green indicates that no invalid contacts were found
in the phonebook (Figure 3).
• Red indicates invalid entries were found in the
phonebook (Figure 4). A plain text log file will be
stored on the SD card indicating which contacts
were problematic. The file can be viewed with a
text viewer (such as Notepad, Wordpad, or Word)
on a computer.
Figure 3. No issues were detected with the
phonebook contact entries

Figure 4. Specific issues were detected with the
phonebook contact entries
