Service
Tip:
In case scan tool communication can't be established with R-36, replace the module with 4F0 910 336 H and proceed to Section 4.
Before considering a software update:
Verify that the customer cell phone is on the compatibility list.
If the customer's cell phone is not on this list:
- Verify that the condition is also applicable with another approved phone.
- Determine if the customer phone functions or malfunctions in another vehicle.
If the universal phone preparation is identified as the root cause for the condition:
Tip:
For successful results, it is important to perform all the sections listed below in the sequence described.
1. Verify software version of phone preparation control unit.
2. Update firmware of the phone preparation control unit, using repair CD 4L0 906 961 Q.
3. Update software of the phone preparation control unit, using repair CD 4L0 906 961 Q.
4. Perform interim software update of the remaining MMI components using Update CD 4F0 906 961 AB.
5. Perform final software update of the remaining MMI components using Update CD 4L0 906 961H.
6. Perform Software Version Management (SVM) feedback documentation.
Section 1. Verifying software version of phone preparation control unit.
1. Press and hold the SETUP button, and then press and hold the RETURN button. Hold both buttons down until the red update screen appears.
2. Select Handyvorb2 to verify Hardware and Software version of the phone preparation.
- If HW-Index: H00 is displayed, replace the phone preparation R-36 with part number 4F0 910 336 H and proceed to Section 4. (See Workshop Manual, Electrical system >> Rep. Gr. 91 >> Infotainment, telephone system >> Removing and installing telephone transmitter and receiver unit -R36.)
- If SW-Index: 0700 and HW-Index does not read H00, proceed to Section 2.
- If SW-Index is not 0700, replace the phone preparation R-36 with part number 4F0 910 336 H and proceed to Section 4.
Section 2. Update firmware of the phone preparation control unit using repair CD 4L0 906 961 Q
Tips:
- Connect a battery charger to the vehicle. (This is necessary because of the long period of time with ignition on during all updates and the final SVM feedback documentation.) Remember to use the Battery Energy Manager posts, and don't charge directly at the battery studs.
- Switch off all unnecessary electrical equipment (HVAC, seat heater, interior/exterior light, etc.).
- Ensure that electromagnetic interference sources (mobile phone or cordless DECT telephone) are not operated in or near the vehicle while individual control units are being updated.
1. Insert repair CD 4L0 906 961 Q in the single CD drive or in the first slot of the vehicle's CD changer.
2. Access the red update screen and select the function SW Update with the lower right soft button.
3. Select CD-ROM with the rotary pushbutton and press to confirm.
Tip:
If the error message Metainfo.txt not found is displayed, you have inserted the wrong repair CD.
4. Select Standard with the rotary pushbutton and press to confirm.
5. Scroll down to the end of the module list with the rotary pushbutton. Select OK to begin the update.
6. The firmware of the phone preparation will be updated now. This may take up to 6 minutes.
Subsequently the internal repair process is performed. This may take up to 5 minutes.
The repair process is complete and the system reinitialize.
To reset the system, scroll down the menu and select Restart MMI.
- If the repair process has been completed successfully, Handyvorb2 will show OK>. Proceed to Section 3, Update software of the phone preparation unit.
- If the repair process has not been completed successfully, Handyvorb2 will show NOT OK>.
Proceed to Step 7.
7. Select Try again? and press to confirm.
8. If the second repair attempt is not completed successfully either, replace the telephone control unit with part number 4F0 910 336 H.
(See Workshop Manual >> Electrical system >> Rep. Gr. 91 >> Infotainment, telephone system >> Removing and installing telephone transmitter and receiver unit -R36).
Afterwards proceed to Section 4.
Section 3. Update Software of the phone preparation control unit, using repair CD 4L0 906 961 Q
1. With the repair CD still in slot 1 of the CD changer, press and hold the SETUP button, and then press and hold the RETURN button. Hold both buttons down until the red update screen reappears. (See Figure 1.)

Model SVM Code
A6 NA4F815
A8 NA4E815 Audi
Q7 NA4L815
Tips:
- After GFF scans all modules, if it states you need to update another module, select No.
- It is normal for GFF to state The SVM action code leads to no result, please contact Technical Assistance. It is not necessary to contact Technical Assistance; the procedure is complete.
The specified SVM code includes all the steps for a multi-step update. Perform the SVM feedback after the complete update is finished.
