2022 Audi S3 Phone Audio Distortion TSB 2071924/1

Symptoms

Owners of 2022 Audi A3, S3, RS 3, Q4 e-tron, and Q4 Sportback e-tron models may experience sporadic phone audio distortion for the driver during phone calls. The primary symptom reported by customers is that "The voice quality on a phone call is sporadically distorted." It is important to note that this issue specifically affects the vehicle's audio for the driver, while the other party on the call will hear clear audio. This condition is distinct from the complaint described in TSB 2065485, which addresses telephone interference synced to the engine's RPM.

Fault Codes / DTCs

Audi Technical Service Bulletin 2071924/1 confirms that no relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's system in connection with this specific "phone audio sporadically distorted" issue. This indicates that the problem does not trigger any diagnostic fault codes that would typically be scanned by a technician.

Technical Background

Audi has identified the root cause of the "phone audio sporadically distorted" problem as a software-related issue within the MIB3 (MQB/MEB) infotainment system. This means the distortion is not due to a faulty hardware component but rather a glitch or bug within the vehicle's software. The manufacturer is actively working on a software update to resolve this condition.

Important Warnings for Owners

Audi has provided critical guidance regarding this issue. Owners should be aware that no repairs are currently necessary or available for the sporadically distorted phone audio. Furthermore, Audi explicitly states: "Do not replace any components for this condition since this will not resolve the customer's concern."

Manufacturer's Guidance and Next Steps

Audi anticipates that a software solution to address the "Audi S3 phone audio distorted" problem will be available by the end of the 4th quarter of 2024, though this timeline is subject to change. Until then, Audi instructs dealerships to take the following steps when a customer reports this concern:

1. Customer Communication: Explain to the customer that a solution is expected by the end of Q4 2024 and that no repairs are necessary at this point. Reiterate that replacing components will not resolve the issue.
2. PSS Record Creation: Create a Pending Service Solutions (PSS) record in the PSS application. This is done through the PSS link available in AccessAudi, under the 'Related Links >> Service' section. This process helps Audi track the prevalence of the problem while awaiting the software update.
