What is Wireless CarPlay?
Wireless CarPlay uses the vehicle's Wi-Fi to provide the same functionality as wired Apple CarPlay without
using a tethered USB connection to the vehicle's infotainment system. Pairing to the vehicle is performed
using the Bluetooth system.
Which Audi MMI systems support Wireless CarPlay?
MIB2+ with ConBox Low
• 2019 Audi e-tron quattro.
• 2019 A6, A7, A8, Q3, and Q8.
• 2020 A6, A7, A8, Q3, Q7, Q8, and e-tron Sportback.
• 2021 Q3.
MIB3 with ConBox High or OCU3/4
• 2021+ A4, A5, A6, A7, A8, Q5, Q7, and Q8.
• 2021+ e-tron quattro and e-tron Sportback.

and the MMI controls the Bluetooth system. For the MIB3 MMI system, the Wi-Fi and Bluetooth systems
are controlled by the ConBox High module.
The MY 2020 A4/A5 models with MIB3 do not support Wireless CarPlay.
How does the apple iPhone establish a Wireless CarPlay connection to the vehicle’s infotainment
system?
Initiating a Wireless CarPlay session can be performed using two different methods.
1. Bluetooth Connection to the vehicle.
2. Wi-Fi connection to the vehicle.
It is important to understand that the two different “pairing” methods have major differences. The first
difference is how the vehicle recognizes the iPhone when the ignition is first started, and the second is how
the iPhone uses data during a CarPlay session.
• The vehicle establishes the Wireless CarPlay session for the Bluetooth pairing method when the vehicle
sees the Apple iPhone connected to Bluetooth.
• For the Wi-Fi pairing method, the vehicle establishes the Wireless CarPlay session when the vehicle sees
the Apple iPhone connected to the in-vehicle Wi-Fi hotspot.
Data usage for each method:
• For the Bluetooth pairing method, the phone always uses the phone’s data plan (LTE) to send and receive
data.
• The phone always attempts to use the Wi-Fi hotspot data for the Wi-Fi pairing method. In some cases, if
the Wi-Fi Assist is turned on in the “Cellular” settings of the iOS, the phone will attempt to use the phone’
s data plan. It is important to note that this doesn’t always work in all situations. The customer should
contact their mobile network provider or Apple customer support if they have issues with this feature.
When using Wired or Wireless CarPlay, the MMI does not store any personal or location data from the
phone. The MMI functions as a remote display for the phone, and only video, audio, and vehicle GPS
data are passed between the phone and the MMI. When the CarPlay session is ended, only the
phone's MAC ID is stored in the MMI. When using navigation applications on the phone, the vehicle's

GPS location information is provided to the phone. The phone's current and historical location
information is never sent to the MMI and is not possible to be stored in the MMI.
The complaints can be caused by various MMI or phone settings, as well as changes caused, for example, by
iOS updates and/or outdated iOS software. We always suggest using the newest available software on the
mobile device.

Initial Pairing for Wireless CarPlay
Prerequisites
1. SIRI must be enabled and configured in the iPhone (Check Settings >> General).
2. Bluetooth must be turned on in the iPhone and MMI (Only used for setup).
3. The iPhone must be discoverable via Bluetooth, which is achieved by opening the Bluetooth pairing menu
on the iPhone.
4. Wi-Fi must be turned on in the iPhone, but no pairing is needed (if it is not on, the iOS software should
prompt the user to turn it on).
5. Make sure that the Bluetooth name in the vehicle’s Bluetooth settings matches the WiFi SSID name in the
vehicle’s WiFi settings (see Figure 1/2).
6. Make sure that a WiFi password is set in the vehicle’s WiFi settings (see Figure 2).

1. The customer
should establish
an Audi
Smartphone
Interface (ASI)
paring using the
MMI and accept
the prompt to
enable wireless
CarPlay (see
Figure 3).
Figure 3. Initial Apple CarPlay pairing prompt on iPhone
2. Accept the prompts in the MMI to enable wireless CarPlay. The MMI shares the Wi-Fi security
credentials to the iPhone over Bluetooth upon accepting. It’s important to note that the customer
will never need to manually pair the iPhone to the Wi-Fi hotspot in the vehicle.
3. At this point, Apple CarPlay should be active in the MMI. Turn off Bluetooth on the iPhone and
turn it back on if the CarPlay session is not active. Once the MMI sees the phone via Bluetooth,
it will connect to Wireless CarPlay over the Wi-Fi hotspot, and then Bluetooth will be disabled in
the MMI.
When using the ASI pairing method above: The iPhone does not use the Wi-Fi hotspot for data
consumption. Instead, a private channel for communication is set up between the MMI and the
iPhone ONLY for Wireless CarPlay. This is why the Audi hotspot name will not be shown in the
settings of the iPhone when connected to the MMI for Wireless CarPlay. The iPhone will continue to
use the LTE network for data. The Bluetooth system is not used once the Car Play session is active
in the MMI and automatically turned off.
Troubleshooting
Concern:
Intermittently after starting the vehicle, wireless CarPlay cannot be started. Upon
touching the tile in the MMI, the tile turns green, but CarPlay does not start.

Technical Service Bulletin
Solution:
Cycle the CarPlay Toggle in the Bluetooth Settings for the vehicle in the iPhone
Settings menu (Figure 3).
Figure 3. Toggle CarPlay option in Bluetooth Settings in iPhone.
This situation can occur when the MMI attempts to start Wireless CarPlay and cannot
find the iPhone on the MMI's Wi-Fi network. Typically, when this occurs, the iPhone is
still active on a different Wi-Fi hotspot (home or work network). Wireless CarPlay
sessions operate over Wi-Fi, but Bluetooth communication is used initially to tell the
MMI that the iPhone is present and ready to use Wireless CarPlay (and shares the WiFi security information).
After the MMI attempts to connect to the iPhone for CarPlay over the Wi-Fi, it soon
realizes it cannot find the iPhone because it is connected to a different hotspot. This
also can happen if the iPhone is manually paired to the 2.4Ghz band of the car's Wi-Fi
hotspot. The MMI has two bands for Wi-Fi, 2.4Ghz (labeled AUDI_XXXX) and 5Ghz
(labeled AUDI_XXXX_5Ghz). Apple CarPlay uses the 5Ghz band, and this is
automatically chosen when the first pairing is done. If the customer tries to pair the
iPhone to the 2.4Ghz band manually, it can create this concern because, from this point
on, the iPhone is constantly switching between the two bands, which can upset
Wireless CarPlay.
To fix this issue, in the iPhone settings, go to the Bluetooth settings (Figure 3, Step 1)
for the MMI and select the little "(i)" next to the MMI's name (Figure 3, Step 2) and
then cycle the "CarPlay" option off and back on (Figure 3, Step 3). If CarPlay does not

anytime this issue occurs again in the future.
Concern:
Since the latest iOS update, the customer has had issues with Wireless CarPlay not
connecting at times.
Solution:
Delete all phone pairings in the ASI and Bluetooth settings from the MMI by longpressing the tile and then select “delete” (see Figure 4).

Concern:
Since the Audi Connect PLUS plan has expired, the customer can no longer use
Wireless CarPlay.
Solution:
Either turn on Wi-Fi assist or delete pairings for Wi-Fi and Bluetooth and perform a
new Bluetooth pairing only.
For this scenario, the customer must have connected the iPhone manually to the MMI's
hotspot using the SSID and password given by the MMI (Wi-Fi pairing method). When
the customer does this, the iPhone uses the Wi-Fi hotspot in the car for sending and
receiving data. If the customer does not have an active Audi connect PLUS plan (not
required for Wireless CarPlay) and the iPhone does not have Cellular Wi-Fi assist
turned on, the iPhone will disconnect from the vehicle's Wi-Fi hotspot if internet data is
not provided. Leaving Cellular Wi-Fi Assist on forces the iPhone to stay connected to a
Wi-Fi hotspot that does not provide internet data but will utilize LTE for the internet
data only. This solution only works with some iOS versions and can break during an iOS
update.

Technical Service Bulletin
If the previous solution does not work, delete the MMI Wi-Fi hotspot settings in the
iPhone, delete the Bluetooth pairing in the phone and MMI, pair the phone again to
Bluetooth and accept the prompts for Wireless CarPlay. DO NOT manually connect the
iPhone to the Wi-Fi hotspot in the car.
Why this is important: If you connect a phone to the Wi-Fi hotspot in the vehicle, the
iPhone will try to use the MMI for data consumption. Since no data can be obtained
with an expired Plus subscription, then Wireless CarPlay will not work since data is
required for CarPlay in general.
Concern:
What if Apple CarPlay does not turn on automatically after turning on the car?
Solution:
Check to ensure the iPhone is not connected to a different Wi-Fi hotspot.
Wireless Apple CarPlay requires that the customer's phone be connected to the Wi-Fi
hotspot of the vehicle, either directly or via the private channel (not seen in the iPhone
Wi-Fi settings). Check to ensure that the iPhone is not connected to the customer's
home or work Wi-Fi hotspot. If the iPhone shows no connection to any Wi-Fi hotspot, it
could be connected to the Wi-Fi using the private Wireless CarPlay. The key here is to
ensure the iPhone is not connected to another Wi-Fi hotspot outside of the car.
Solution:
The phone offers a setting to disable the automatic CarPlay connection to the vehicle.
Please check the setting in the phone and make sure it is active if you desire CarPlay
to automatically start when you enter the vehicle.
Concern:
Wireless CarPlay works intermittently. What could be causing this?
Solution:
Unlock iPhone or turn off USB accessories security feature (Customer must be aware
of this security feature before turning it off).
Apple has instituted security features in iOS, starting with iOS 12. The newest feature
locks out the use of connected USB accessories, including the MMI, if the iPhone has
not been unlocked in the last hour before connecting the iPhone to the vehicle's USB
or wirelessly for CarPlay. Unlock the iPhone to fix the customer's concern.
Question:
What is the 5Ghz Wi-Fi hotspot seen in the vehicle?
Answer:
5Ghz Wi-Fi is part of the dual-band high-speed Wi-Fi system in the MMI. Most modern
home routers are now dual-band, offering a 2.4Ghz band and a 5Ghz band. In most
cases, upon pairing the iPhone to the MMI, the iPhone will connect to the 5Ghz
hotspot, which is normal, but this connection may NOT be shown in the iPhone
