2023-2026 Audi Wireless Charging Not Working TSB 2064681

Owners of 2023-2026 Audi vehicles equipped with the Audi Phone Box may encounter problems with the wireless charging feature. This Technical Service Bulletin (TSB) 91 24 73 2064681/5, which supersedes TSB Group 91 number 23-46, provides guidance on diagnosing and understanding these issues. The TSB highlights that the wireless charging system can be affected by various external factors, leading to a range of symptoms.

Symptoms of Wireless Charging Issues

If you own a 2023-2026 Audi and are experiencing problems with your Audi Phone Box, you might notice one or more of the following:

• Your mobile device sometimes cannot be charged wirelessly.
• The phone gets very hot during charging, leading to charging cancellation or the phone entering thermal protection mode.
• The phone is not charging, and the MMI displays the message: "The device cannot be charged as there is another object in the charging cradle."
• The phone does not begin charging after being placed in the charging cradle.
• The phone or individual processes on the device shut off due to excessive heat generation.
• The mobile device supports wireless charging, or you are using a charging cover that enables wireless charging, yet the issue persists.

These symptoms indicate a problem with the Audi wireless charging not working as expected.

Diagnosis and Trigger Conditions

Before seeking service, there are several checks you can perform to help diagnose why your Audi wireless charging not working. These steps are similar to those a technician would follow:

• Verify MMI Settings: Ensure that wireless charging is activated within your Audi's MMI settings. Refer to your vehicle's owner's manual for specific instructions.
• Clear the Charging Cradle: Make sure there are no objects other than your mobile phone in the charging cradle. Foreign objects can interfere with the charging process.
• Remove Phone Case/Cover: If your phone is in a case or has a back cover, try charging it without the case or cover to see if the issue resolves.
• Proper Phone Positioning: The placement of your phone significantly impacts charging effectiveness. Ensure the phone is centered in the charging cradle during testing. The charging cradle uses multiple coils, but only one is active at a time. Misalignment, especially with smaller devices, can lead to energy loss and increased heat.
• Battery Level Check: A device with a low battery (below 80%) may generate more heat during wireless charging. Check if the problem persists when your phone's battery level is higher.
• Close Intensive Apps: If you are using intensive applications (including CarPlay or AndroidAuto) while charging, these can cause the device to become very hot. Close all apps and stop them to see if the concern is still reproducible.
• Allow Time for Charging: It can take up to 60 seconds for wireless charging to initiate.
• Test with Another Phone: If possible, try charging a different mobile phone in the cradle to determine if the issue is with the vehicle's system or your specific device.

If these troubleshooting steps do not resolve the Audi wireless charging not working issue, further diagnosis using Guided Fault Finding may be necessary by a qualified technician.

Important Warnings for Owners

There are specific considerations for certain mobile devices and usage patterns:

• iPhone 12, 13, and 14 Compatibility: For Apple iPhone generations 12, 13, and 14, it's important to note that their MagSafe charging technology is not fully compatible with the industry-standard Qi system used in your Audi. This can result in higher power losses and increased heat generation, especially during intensive use while charging. This behavior is considered normal for these devices and is caused by the phone, not the vehicle. Do not replace parts as that will not resolve the customer complaint.
• Intensive Use Advisory: If intensive use of your mobile device is required while in the vehicle, Audi recommends using a USB connection instead of wireless charging to prevent overheating and ensure consistent power delivery.

Owner Action

If you are experiencing issues with your Audi wireless charging not working, first perform the diagnostic steps outlined above. If the problem persists, especially after considering the specific warnings regarding iPhone compatibility and intensive use, contact your authorized Audi service center. While this TSB (reference 2064681) is informational, understanding these points can help you communicate effectively with your technician and avoid unnecessary repairs.
