2022512/3
December 7, 2011.
Supersedes Technical Service Bulletin Group 91 number 10 - 65 dated October 18, 2010 for reasons listed below.
Affected Vehicles
284
Condition
^ The Bluetooth connection is disrupted and cannot be restored.
^ A mobile phone cannot be connected to the vehicle via Bluetooth.
Technical Background
3G MMI hardware and software-related issues.
Production Solution
New 3G MMI hardware and new software (ZUG 0114).
Service
1. Determine whether the customer's phone is on the approved mobile phone list. (Review list at www.audiusa.com/bluetooth.)
2. Ask the customer whether the mobile phone has been successfully connected to this vehicle via Bluetooth.
3. Determine whether another approved phone can be connected to the vehicle via Bluetooth.
4. Determine whether the customer's phone can be connected to another vehicle equipped with 3G MMI via Bluetooth.
5. Determine whether adaptation channel 17 (Bluetooth on/off) is set to 1 in the 3G MMI main unit, address 5F.
If points 1, 2, 4 and 5 apply but not point 3 perform the following:
Read measuring value block 144 in the main unit, address 5F.
^ If value 2 is "1" (Bluetooth switched off), then reset the value to 0 and then back to 1 in adaptation channel 17.
^ If value 2 is "0" (Bluetooth switched on), then continue with analysis. The main unit, 5F, does not need to be replaced.
^ If value 2 is "2" (Bluetooth doesn't work), then read measure value block 151 in the main unit, 5F. If the value reads "Not Possible", then proceed
as follows:
^ Replace the main unit for 3G MMI systems with navigation. Check the 3G MMI software level and if necessary update the software by following
the instructions below.
Tip: Refer to your parts department for the correct main unit part number.
Update software of the 3G MMI system - A6 and Audi Q7 models equipped with radio plus and not equipped with navigation by following the
instructions below.
Tip: For successful results, the steps must be performed in this sequence.
1. Check 3G MMI system software version
2. Update software of the 3G MMI system
3. Perform feedback documentation to the SVM
1. Check 3G MMI system software version
1. Switch on ignition and wait approximately 1 minute.
285
2. Press the SETUP and RETURN buttons simultaneously and hold both buttons down for about 5 seconds.
If this message is displayed, the system is not yet completely initialized. Wait a few seconds, then press the RETURN button.
3. Read current MMI train (Zug) version.
4. The train (Zug) versions listed in the table above must be updated.
P versions are production build.
K versions are service updates.
2. Update software of the 3G MMI system
1. Connect an approved Audi battery maintainer/charger to vehicle.
286
2. Switch off all unnecessary electrical equipment (blower, seat heater, interior light, etc.).
Tip: Also make sure that no electromagnetic interference sources (mobile phone) are operated in or near the vehicle while individual control units
are being updated.
Tip: For complete and detailed instructions for the 3G MMI system update, refer to the attached instructions. (Note: The attached instructions are
generic. Some portions may not apply to this specific TSB. Importing and exporting customer code data is not necessary for this 3G MMI update
system.)
3. Insert update CD into the 3G MMI main (head) drive unit located in the center of the instrument panel.
4. Start the software update.
5. After the software update has been performed, confirm the Abort (cancel) documentation" selection. The 3G MMI system will restart. Then
perform the feedback documentation.
3. Perform feedback documentation to the SVM
1. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
2. Confirm any proposed parameter settings and coding.
3. Then perform test program "5F - Information electronics, resetting fault memory" to clear any faults in the system.
Tip: No control unit is flashed as part of the feedback documentation to the SVM. Do not perform any updates of control units. Do not replace any
control units.
