This behavior is addressed by Audi Technical Service Bulletin (TSB) 55 23 80 2067818/2, issued on October 16, 2023.

Important Information for Owners

This TSB is critical for owners to understand, as it prevents unnecessary diagnostic work or attempted repairs for a feature that is no longer supported. Audi explicitly states that no work is required to address the non-functional Audi gesture-controlled rear lid.

• No notification: Audi is NOT notifying consumers about this change. Owners should be aware that the feature is no longer available.
• Do not replace parts: Do not attempt to replace components related to the gesture-controlled rear lid system, as this will not resolve the issue. The feature cannot be enabled, even if some parts were initially installed at the factory.
• No warranty claim: This TSB is informational only and is not applicable to any Audi warranty claims.

Symptoms

The primary symptom owners will experience is that the gesture-controlled rear lid not working. This means the rear lid (trunk or tailgate) will not open or close by performing a kicking motion under the bumper, which was previously a supported feature.

Technicians may find the following Diagnostic Trouble Code (DTC) stored in the vehicle's system:

This DTC, B13034A, indicates that an incorrect component is installed in the Comfort System Central Control Module. However, as explained in the TSB, this is not a fault requiring repair.

What Owners Should Know
