2019-2025 Audi Roadside Assistance Call Hangs Up TSB

Symptoms

Owners of 2019-2025 Audi Q3 models, and 2022-2025 Audi A3, S3, and RS 3 models equipped with Online Services and an OCU may experience an issue where their online roadside assistance call or Audi incident assistance call automatically hangs up after 30 seconds. The primary customer complaint is that the "online roadside assistance call / Audi incident assistance call cannot be made and is hung up automatically if the call center doesn't pick up within 30 seconds." This occurs specifically when the call center agent or an answering machine does not answer the call within the initial 30-second window.

Diagnosis / Trigger Conditions

This behavior is a known characteristic for MQB vehicles, specifically the Audi A3 and Audi Q3, that are equipped with the OCU3 -J949- control unit (identified by address word 0075). The system implements a software timeout mechanism for pending calls. If the call center agent or answering machine fails to pick up the call within 30 seconds, the OCU3 is designed to automatically terminate the call. This is not a fault but a system design for managing call connections.

Important Warnings

Audi has issued a critical notice regarding this condition under Technical Service Bulletin 91 24 58 2074927/1. Owners and technicians should be aware that there is no reason to replace components to resolve the issue of the Audi S3 roadside assistance call hangs up. The TSB explicitly states: "If components are replaced without good reason under warranty, the claim will be charged back." Furthermore, this Technical Service Bulletin is informational only and is not applicable to any Audi Warranty claim for repair. It does not cover any costs associated with component replacement.

Repair Procedure Summary

According to Audi Technical Service Bulletin 91 24 58 2074927/1, no repair is necessary for this customer complaint. The behavior where the online roadside assistance call or Audi incident assistance call hangs up after 30 seconds is a result of a designed software timeout within the OCU3 system, not a malfunction requiring parts replacement or a software update. Therefore, there are no specific repair steps, parts, or tools required to address this condition.

Owner Action

If you experience your Audi S3 roadside assistance call hangs up, or if the call disconnects on any of the other affected models (2019-2025 Audi Q3, 2022-2025 Audi A3, S3, or RS 3), the manufacturer recommends a simple workaround. You should reinitiate the online roadside assistance call. You may need to attempt this multiple times until the call center successfully answers the call. Since no repair is required, owners do not need to visit a dealership for this specific issue, nor are there any special parts or tools required.
