2023 Audi Gesture-Controlled Rear Lid Not Working TSB

Understanding the 2023 Audi Gesture-Controlled Rear Lid Issue

Owners of various 2023 Audi models may notice that their vehicle's gesture-controlled rear lid function is not operating as expected. This behavior, often accompanied by diagnostic trouble code (DTC) B13034A, is not indicative of a fault requiring repair. Technical Service Bulletin (TSB) 2067818/1, issued on August 18, 2022, clarifies that Audi has discontinued the gesture-controlled rear lid feature for all Model Year 2023 vehicles.

This means that if you own a 2023 Audi and your Audi gesture-controlled rear lid is not working, it is functioning as intended by the manufacturer. The system has been deactivated, and no service action or repair is required to restore the functionality.

Symptoms

The primary symptom owners will observe is that the Audi gesture-controlled rear lid does not open or close when attempting to use the foot-swipe gesture. This is the expected behavior for Model Year 2023 vehicles.

Fault Codes / DTCs

If a diagnostic scan is performed, technicians may find the following Diagnostic Trouble Code (DTC) stored in the vehicle's system:

• B13034A: "Control module for rear lid opening, incorrect component installed in the Comfort System Central Control Module (address word 0046)."

This DTC indicates that the control module for the rear lid opening is present but is not correctly integrated or configured for the now-discontinued gesture control function.

Important Warnings for Owners and Technicians

Audi TSB 2067818/1 provides critical information that prevents unnecessary diagnostics and repairs:

• No Work Required: "No work is required" to address the non-functional gesture-controlled rear lid on 2023 models.
• Feature Cannot Be Enabled: "This feature cannot be enabled even if some of the parts of the system were installed at the factory." Owners should not expect the function to be activated.
• Ignore DTCs: Any related event memory entries, such as DTC B13034A, should be ignored by workshop technicians. These codes do not signify a fault that needs correction.
• Informational Only: This TSB is "informational only and not applicable to any Audi warranty." This means no warranty claim can be made for this specific issue.

Technical Background

Audi has confirmed that the gesture-controlled rear lid function has been officially discontinued for all Model Year 2023 vehicles across the affected models. This decision means that even if some components (like a control unit or sensor) for the system were installed in early 2023 production vehicles, the functionality itself is no longer supported or enabled.

What Owners Should Know

If you own a 2023 Audi from the affected list and your gesture-controlled rear lid is not working, there is no need to visit a dealership for diagnosis or repair. This is a deliberate change by the manufacturer, not a defect. The system is designed to be inactive, and attempts to enable it or clear associated fault codes like B13034A will not restore the function.

This information helps owners understand that the absence of the gesture-controlled rear lid operation is normal for their 2023 model year vehicle, preventing confusion and unnecessary service appointments.
