2021 Audi Power Rear Lid Cannot Be Opened TSB 2064020/2

Audi has released Technical Service Bulletin (TSB) 2064020/2 to address a condition where the power rear lid on certain 2021 Audi models cannot be opened. This TSB, which supersedes an earlier bulletin (21-58 dated July 16, 2021), provides diagnostic and repair information for this issue.

The problem is typically caused by an internal blockage within the rear lid's closing assist motor, preventing the rotary latch from releasing. Owners searching for why their 2021 Audi power rear lid isn't working should consult this information.

Symptoms

Owners will observe that the power rear lid cannot be opened. This malfunction occurs regardless of whether the vehicle key, the interior/exterior buttons, or the emergency release mechanism is used.

Fault Codes / DTCs

When diagnosing this issue, technicians may find one or both of the following Diagnostic Trouble Codes (DTCs) stored in the rear lid electronics control module (J605):

Code	Description
B113E29	Closing assistance Range/Performance
B113E07	Closing assistance mechanical malfunction

Diagnosis / Trigger Conditions

The root cause of the 2021 Audi power rear lid malfunction is identified as component-related deviations within the rear lid closing assist motor. These deviations can lead to an internal blockage of the motor. When blocked, the motor cannot release the rotary latch of the rear lid lock, making it impossible to open the lid.

Important Warnings for Owners

Owners should be aware of specific conditions related to this repair:

• If the vehicle is outside of its warranty period, this Technical Service Bulletin is for informational purposes only, and repair costs may apply.
• If the power rear lid is severely blocked and the trim must be removed from inside the vehicle, there is a risk of irreparable damage to the trim on some models. Technicians are advised to document any damage with photos.

Repair Procedure Summary

Audi's recommended repair procedure, outlined in TSB 2064020/2, involves the following steps:

1. Initial Attempt to Release Blockage: If the power rear lid cannot be opened, technicians should first try gently knocking on the rear lid in the area of the closing assist motor. The vibrations from this action may release the internal blockage.
2. Trim Removal (if necessary): If knocking does not resolve the issue, and the rear lid remains blocked, the rear lid trim must be carefully removed from inside the vehicle using standard tools. This step may require extra caution to avoid damaging the trim.
3. Access and Replacement: Once the rear lid is open and the lower trim panel is removed (following the Elsa Repair Manual), the closing assist motor is replaced.
4. Verification and Reassembly: After replacing the motor, its operation and that of the power rear lid are checked. Finally, the rear lid lower trim panel is reinstalled, and any stored DTCs are cleared from the system.
