2022 Audi A5 Emergency Call Module Service Action 90U3

Problem Description

Audi has identified that a small number of vehicles, including the 2022 Audi A5 Sportback, may have been manufactured with an emergency call module control unit and communication unit that has an incorrect serial number (IMEI). This manufacturing defect can lead to a significant issue where the network provider might "deactivate the mobile phone reception as a consequence". This directly impacts the functionality of the emergency call system, which relies on active mobile connectivity. This service action, identified as 90U3, aims to rectify this manufacturing error.

Symptoms

The primary symptom of this issue is the potential for the vehicle's "mobile phone reception deactivated". While the document does not specify a direct dashboard warning message, this condition would prevent the emergency call system from functioning correctly and could lead to other connectivity problems within the vehicle's telematics system. Owners may notice a loss of mobile network service for the vehicle's integrated systems.

Diagnosis and Trigger Conditions

The root cause of this problem is an incorrect International Mobile Equipment Identity (IMEI) serial number within the emergency call module control unit. This is a manufacturing defect, not a fault that can be triggered by specific driving conditions or user actions. To determine if a 2022 Audi A5 emergency call module is affected, authorized Audi dealers will check the vehicle's VIN against the campaign database in Elsa. The campaign status must show as "open" for the repair to proceed.

Repair Procedure Summary

To resolve the issue identified in Service Action 90U3, authorized Audi dealers will replace the emergency call module control unit. The repair process involves several steps for the technician:

1. Vehicle Verification: The technician must first enter the vehicle's VIN into the Elsa system and navigate to the "Campaigns/Actions" screen to confirm the campaign is open for the specific vehicle. An Elsa screen print showing the action as "open" on the day of repair must be attached to the repair order.
2. Pre-repair Checks: All existing Safety Recalls must be completed prior to performing this campaign. If multiple software update Campaign/Actions are open, they must be performed in order of their start date, with the oldest being completed first.
3. Module Replacement: The core of the repair involves replacing the affected Control Module for Emergency Call Module and Communication Unit J949. Technicians are instructed to follow the detailed steps outlined in the ELSA Repair Manual under the path: "Electrical System > Communication > 91 Communication > Mobile Online Services > Control Module for Emergency Call Module and Communication Unit J949, Removing and Installing". This procedure includes connecting a battery charger to the vehicle during the repair to maintain power.
4. Post-repair Operations: After the physical replacement, GFF Operations (Guided Fault Finding) may be performed, as indicated by labor operation 0150 00 00. The total estimated time for the repair is approximately 130 time units for the module replacement, plus 10 time units for connecting the battery charger.
