CONDITION

Customer states: 

Various complaints regarding Apple CarPlay or Android Auto.

Workshop findings: 

Apple CarPlay or Android Auto is not working properly.

TECHNICAL BACKGROUND 1

Complaints can be caused by various MMI settings or phone settings, as well as limitations with regard to the phone's software. We therefore recommend you always check the complaint using the newest software version (of both the app and the phone's operating system).

PRODUCTION SOLUTION

Not applicable.

SERVICE

If there is no appropriate TSB, please always check the following points/settings first as they may solve the customer's concern. 

Check the following:

1. Is the Apple CarPlay function activated on the phone? Settings => General => CarPlay
2. Is the Android Auto app installed?
3. Is Android Auto available in your country?
4. Is the latest software version installed on the phone? Please check and have the customer install it if necessary.
   1. Apple CarPlay: iOS 15.5 (June 2022) (no additional app required).
   2. Android Auto: Android 5.0 or higher (8.0 for wireless) + Android Auto app.
5. Is a 5GHz network permitted in your market? If not => wireless ASI not possible.
6. Please note for MIB2+ vehicles from model year 2019: Wireless Apple CarPlay is not available for these vehicles; Apple CarPlay can only be used via USB.
7. Please check whether privacy mode is deactivated on the MMI.
   1. NOTE: If privacy mode is switched on, the 5 GHz Wi-Fi will not be active and wireless Apple CarPlay will therefore not be available.
8. Does resetting the phone/app to factory settings resolve the issue? Please check.
9. Check whether the complaint occurs again after you have performed a terminal 30 reset of control unit for information electronics (diagnostic address 5F) and connectivity box/OCU (diagnostic address 75). Remove the relevant fuses to do this. Please also remember the backup battery.
10. Check whether the USB cable is the cause of the issue: Use a different USB cable (refer to Audi Genuine Accessories) and check whether the complaint occurs again.
11. Check whether it is possible to charge the phone via USB. If not, we recommend you check the USB interface.
12. Can the problem be solved by restarting the iPhone/Android phone (e.g. required for older iOS version or for reconnect issues)?
13. Have the activation codes been run? Run activation codes again via GFF:
    1. Please use the test program "SVM activations" or "SVM activations (FoD)" (depending on the model) for this purpose.
    2. IMPORTANT: The activations that need to be run are in the control unit for information electronics (diagnostic address 5F) or the gateway (diagnostic address 19), depending on the model and MIB system. This is described in the test program.
14. Reconnect the phone completely (e.g. required if pressing "ASI" tile does not do anything):
    1. Phone menu => Device overview => Press and hold button => Delete phone.
    2. ASI menu => Device overview => Press and hold button => Delete phone or reset to factory settings.
    3. Delete MIB from iPhone: Settings => CarPlay => My Cars => Forget This Car.
    4. Restart iPhone.
    5. Reconnect phone with MIB.
15. If there is no response when you press the Apple CarPlay tile, check whether a Wi-Fi connection has been established when you do so. Check on the phone/on the MMI. If a Bluetooth symbol is shown on the MMI, Wi-Fi is not active and Apple CarPlay is therefore not available.
16. Please also test other available phones on the affected vehicle. Please test Apple CarPlay and Android Auto with both a USB cable and a Wi-Fi connection (if available).

If the above checks do not solve the problem, please create a TAC Ticket if you are able to reproduce the complaint in the workshop. The following information must be included:

1. Video of the complaint, ideally showing the MMI display and phone display.
2. Does the complaint occur both with an iPhone and with an Android phone?
3. Which phones were used: iPhone X/iPhone 11/Samsung "XYZ"...?
4. Which iOS version is installed on the iPhone on which the complaint occurs?
5. Did the complaint also occur with any earlier iOS versions?
6. Does the customer's phone work with a comparable vehicle? Please include the VIN of the vehicle used for comparison.
7. Please describe the conditions as precisely as possible:
   1. Does the complaint occur while driving?
   2. Was a particular message shown at the time when the complaint occurred? (e.g. phone call)
   3. Check the Wi-Fi connection. Was it dropped or did the quality decrease?
   4. When the complaint occurred, was it the first time in the bus cycle that Apple CarPlay was activated, or had it already been activated previously?
   5. Does the complaint always occur after a certain period of time?
   6. Was Apple CarPlay previously active and then the screen suddenly went black, or did the black screen occur the first time Apple CarPlay was switched on?
   7. Does the complaint occur during start-up?
   8. Delays in establishing a Wi-Fi connection may occur during start-up; this may result in delays/lack of response when switching on wireless Apple CarPlay. You should therefore always check the Wi-Fi connection during start-up: If a Bluetooth symbol is shown on the MMI, a Wi-Fi connection has not yet been established.
   9. Was the vehicle in bus sleep mode beforehand or did the complaint occur after only a short stationary period or after the ignition was switched off and on again?
   10. Which source was the system set to when it was shut down before bus sleep mode?
   11. Which source is the system started up with?
   12. Is there any audio output and if so, which type of audio can be heard?
   13. Was the Apple CarPlay button pressed during start-up? If so, which source was the system started up with beforehand?
   14. Does the system switch automatically from radio to Apple CarPlay? If so, after it switches to Apple CarPlay, what is displayed, what audio is played (if any)?
8. For general complaints:
   1. Does unlocking the screen solve the problem on an iPhone?
   2. Which app creates problems with Apple CarPlay?
   3. Can the Apple CarPlay function be started via the iPhone?
   4. Does the issue with Apple CarPlay also occur on the original Apple app (e.g. Apple Music)?
   5. Is the error shown on the Apple CarPlay screen or the MMI HMI? Please attach a photo.
9. Also required for wireless complaints
   1. Does connecting the phone via USB to charge solve the problem?
   2. Does the phone charge at all via USB?
   3. Does the complaint regarding wireless Apple CarPlay also occur when the phone is connected via USB?
   4. Is Wi-Fi active when the complaint occurs? Check the phone's display or the MMI display: If the Bluetooth symbol is shown on the MMI display, Wi-Fi is not active.
10. For complaints with a black screen:
    1. Take a screenshot with the phone. Two images will be saved; please attach both of them. The image of Apple CarPlay is particularly important.
11. Please attach a current diagnostic log.
12. Please always specify what resolves the issue.

1. It resolves itself (directly or after a certain period of time).
2. Switching ignition off and on again.
3. Terminal 30 reset.
4. Resetting to factory settings.
5. Switching smartphone off and on again.
6. Etc.
