This Technical Service Bulletin (TSB) applies to a range of Audi models from model year 2021 through 2026, identified by type codes such as 4N*, 4A*, 4K*, 4M*, F3*, and 8Y*. It also references PR numbers like UF7, UF8, UE4, and UE7, which typically denote specific equipment configurations related to the USB interface within the vehicle.

TSB Revision History

TSB 2066315/3 has been updated multiple times to ensure accuracy and expand its applicability. The revision history is as follows:

• Revision 3: Revised header (Add Model Years)
• Revision 2 (05/18/2023): Revised header (Add Model Year)

Symptoms and Customer Complaints

Owners of affected Audi models may experience several issues related to a damaged USB socket. The most common complaints reported to service centers, as categorized in the TSB, include problems with the information, navigation, communication, and entertainment systems, specifically concerning the MMI and drive device functions when attempting to connect a USB device. These manifest as:

• "functionality -> no function" for connecting a USB device.
• "component, automotive fluids -> blocked" when trying to connect a USB device.
• "component, automotive fluids -> sticks" when attempting to connect a USB device.
• "functionality -> too difficult to move" for the USB connection.

More commonly, customers report specific functional problems such as:

• "There is no media playback via USB."
• "The USB drive is not recognized."
• "Cell phone is not recognized via USB."

These symptoms collectively indicate a failure in the USB connection, preventing the infotainment system from properly interacting with external devices.

Workshop Findings and Technical Background

When vehicles are brought to a workshop with these complaints, technicians frequently identify a "USB socket fault." The technical background provided in TSB 2066315/3 highlights that the deformation or damage to the USB socket is often due to external factors. The bulletin includes a visual reference of a deformed USB-C port, illustrating the type of damage observed.

Possible causes for this deformation and subsequent malfunction include:

• Improper Insertion: If a USB stick is improperly inserted into the USB socket, particularly at an angle, it can cause physical stress and damage to the internal components or the socket housing.
• Non-Standard USB Sticks: The use of USB sticks or other devices that do not conform to standard specifications in terms of size, shape, or construction can also lead to undue force or misalignment during insertion, resulting in damage.

Technicians are specifically advised to "Check carefully whether this could be the customer's fault" by examining the USB sticks used by the customer, as these could be the direct cause of the damage.

Important Warnings Regarding Warranty Coverage

This TSB contains critical information regarding warranty coverage for the Audi USB socket loose issue. Audi explicitly states that this type of damage is considered to be caused by external influences, not a manufacturing defect. Therefore, owners should be aware of the following crucial points:

• "This damage is due to outside influence and is not covered by any Audi Warranty."
• "Any parts that are replaced under warranty will be charged back." This means that even if a repair is performed under a warranty claim, the cost for the parts will be debited back to the dealer, effectively making the customer responsible for the expense.
• "This complaint is caused by external influences and is therefore not covered by warranty."

Essentially, Audi views the damage to the USB socket as a result of user interaction or the use of incompatible accessories, rather than a defect in material or workmanship. As such, repairs for this specific issue will not be covered under the standard Audi warranty.

Production Solution and Service Measures

Given that the root cause of the Audi USB socket loose issue is attributed to external factors, the TSB specifies that there is "No measure" as a service action and that a "Production Solution" is "Not applicable." This indicates that Audi does not plan to implement a factory-level fix or a specific service campaign to address this issue, as it is not considered a design or manufacturing flaw.

Instead, the TSB advises technicians to "Refer to technical background," which details the potential causes of damage related to improper USB stick insertion or non-standard USB devices. This guidance reinforces that the responsibility for preventing such damage lies with the user.

Required Parts and Tools

The TSB does not list any specific special tools or part numbers for a warranty-covered repair, precisely because this issue is not covered under warranty. Should a damaged USB socket require replacement, the necessary parts would be ordered through standard Audi parts channels, and the cost would be borne by the customer. Technicians are reminded to always check with their Parts Department and/or ETKA for the latest information and parts bulletins, and to consult the Repair Manual for any fasteners, bolts, nuts, and screws that require replacement during the repair process.

Owner Action and Prevention

If you are experiencing issues with your Audi's USB socket, particularly if it appears loose, missing, or pushed in, it is important to understand the implications of TSB 2066315/3. To prevent damage and avoid out-of-pocket repair costs, consider the following:

• Inspect USB Devices: Always ensure that any USB stick or cable you intend to use is standard-sized and compatible with your vehicle's USB port. Avoid using oversized, oddly shaped, or poorly manufactured devices.
• Proper Insertion Technique: When inserting a USB device, always do so carefully and ensure it is aligned correctly with the port. Avoid forcing the device or inserting it at an angle, as this is a primary cause of the Audi USB socket loose problem.
• Avoid Excessive Force: Never apply excessive force when connecting or disconnecting USB devices. If a device does not slide in easily, re-check its orientation and compatibility.
• Be Aware of Warranty Limitations: Be prepared that any repair or replacement of a damaged USB socket will likely not be covered under your Audi warranty and will incur charges. This TSB explicitly states that such damage is due to external influence.
• Consult Your Dealer: If the problem persists or you are unsure of the cause, contact an authorized Audi service center for diagnosis. They can confirm if the damage is indeed due to external influence and provide options for repair, albeit at your expense.

This TSB serves as an advisory to both technicians and owners, clarifying the nature of USB socket damage and its warranty status for the Audi USB socket loose issue, emphasizing user responsibility in preventing such occurrences.
