2022 Audi A5 Emergency Call Module Service Action 90U3

Audi has released Service Action 90U3, an important dealer communication regarding the emergency call module control unit in certain 2022 Audi A5 vehicles. This service action addresses a manufacturing defect that could impact the vehicle's communication capabilities.

The core of the issue for the 2022 Audi A5 emergency call module lies with an incorrect International Mobile Equipment Identity (IMEI) serial number. This manufacturing error on the emergency call module control unit and communication unit can lead to significant problems, as the network provider may "deactivate the mobile phone reception" for the vehicle as a consequence. This affects the ability of the vehicle to use its integrated mobile services, including emergency call functions.

Symptoms

Owners of affected 2022 Audi A5 Sportback vehicles may experience a loss of mobile phone reception. This can manifest as an inability to make or receive calls through the vehicle's integrated system, and critically, it can prevent the emergency call system from functioning correctly. The primary symptom is the potential for the network provider to deactivate the mobile phone reception due to the incorrect IMEI.

Diagnosis / Trigger Conditions

The root cause of this problem is an incorrectly manufactured emergency call module control unit and communication unit, specifically concerning its serial number (IMEI). This condition is present from the time of manufacturing. Technicians can identify affected vehicles by checking campaign open inventory reports or OMD (Open Market Data) systems, as outlined in the ELSA/ServiceNet instructions for complete repair and claiming procedures.

Repair Procedure Summary

To resolve the issue with the 2022 Audi A5 emergency call module, the repair involves replacing the faulty emergency call module control unit. This is a straightforward replacement procedure designed to restore proper mobile phone reception and ensure the emergency call system functions as intended. Dealerships are instructed to refer to ELSA/ServiceNet for detailed repair and claiming instructions.

Important Warnings

Audi has emphasized that all affected inventory vehicles must be repaired before delivery to consumers. This ensures that new vehicle owners do not experience this communication issue from the outset. Furthermore, dealers are instructed to "Schedule owner repairs immediately" once the owner mailing is initiated in August 2022.

Owner Action

If you own a 2022 Audi A5, particularly an A5 Sportback, and are concerned about this issue, you should contact your authorized Audi dealership. While an owner mailing was scheduled for August 2022, it is always prudent to verify if your vehicle is part of Service Action 90U3. The repair, which involves replacing the emergency call module control unit, will be performed free of charge under this service action.
