2022 Audi A3 'Audi pre sense: fault' TSB

Symptoms

Owners of the 2022 Audi A3 equipped with FPK Medium and Audi pre sense may notice a specific message appearing in their instrument cluster. After turning on the ignition or starting the vehicle, the message "Audi pre sense: fault. Please contact service" is displayed. This message typically appears only briefly, for less than one second.

It is important to note that despite this warning, there is no functional restriction of the Audi pre sense system. The system continues to operate normally, providing its intended safety features.

Fault Codes / DTCs

When this particular issue occurs, workshop findings indicate that no relevant Diagnostic Trouble Codes (DTCs) are stored in the vehicle's systems. This absence of DTCs helps confirm that the problem is not a hardware malfunction but rather a software anomaly.

Diagnosis and Trigger Conditions

The root cause of the erroneous "Audi pre sense: fault. Please contact service" message is identified as a software timing issue. This timing problem causes the malfunction message to be displayed incorrectly shortly after the vehicle starts up. The Audi A3 pre sense fault is purely a display anomaly and does not affect the system's functionality.

Repair Procedure Summary

To address the Audi A3 pre sense fault, a software update for the Instrument Cluster -J285- is required. This update is performed using the Software Version Management (SVM) system.

Technicians must follow the instructions outlined in TSB 2011732, which covers general SVM operating procedures. The update process involves using DoIP (Diagnostics over Internet Protocol) for flashing control modules. It's crucial to ensure DoIP is active, which can be confirmed by a red LED on the VAS 6154(A) diagnostic tool.

The Instrument Cluster -J285- (diagnostic address 0017) needs to be updated using the SVM action code 17A035. This update will bring the instrument cluster software to version 5345 or higher. Specifically, for old software part numbers 8Y0920700B (version 5320) and 8Y0920800B (version 5330), the new software part numbers will also be 8Y0920700B and 8Y0920800B, respectively, but updated to version 5345 or higher.

Required Tools or Parts

To perform this software update, an authorized Audi service facility will utilize the ODIS diagnostic system with DoIP capabilities and a VAS 6154(A) diagnostic interface. The specific software part numbers involved in the update are 8Y0920700B and 8Y0920800B, which will be updated to version 5345 or higher.
